Participants received notifications through an app asking if they were high, and were then prompted to answer questionnaires that assessed their emotional state, motivation levels, willpower and self-regulation.</p> <p>Inzlicht says the most interesting finding relates to motivation, with participants found to be just as willing and motivated to exert effort in completing a task when high compared to when sober.</p> <p>Past research has shown mixed results when it comes to chronic cannabis use and motivation, with Inzlicht noting much of it relied on limited experimental designs that didn't account for differences between cannabis users and non-users, including variations in personality, mental health or use of other psychoactive substances.</p> <p>He says this study accounted for those pre-existing differences and also looked at chronic cannabis use while participants were actively high.</p> <p>The researchers did find that being high was associated with lower levels of self-regulation, an important trait for being able to accomplish tasks. Specifically, chronic users reported being more impulsive, less thoughtful and less orderly.</p> <p>鈥淭hese things can detract someone from getting stuff done, but we didn鈥檛 find it made them less hard-working, responsible or able to focus,鈥 says Inzlicht, who runs the&nbsp;Work and Play Lab, which does research on self-control, motivation and empathy as well as social media, digital devices and recreational cannabis use.&nbsp;</p> <p>Chronic cannabis users were also found to experience a boost in positive emotions such as awe and gratitude when they were high, and a reduction in some negative emotions such as fear and anxiety. However, more chronic users were found to experience more negative emotions while high as well as while sober.</p> <p>The study also found no evidence of a 鈥渨eed hangover鈥 the day after cannabis use.</p> <p>Inzlicht notes that studying the effects of daily cannabis use was difficult in the past due to its legal status, and that most scholarship on the topic focused on negative impacts in an effort to curb use.</p> <p>Now that cannabis is legal in Canada, however, Inzlicht says he expects there will be more research focusing on both positive effects and risks.</p> <p>鈥淭he cannabis literature, historically, tended to focus a lot on the negative medical consequences of chronic use,鈥 says Inzlicht. 鈥淧art of the motivation for this study is to take a neutral, clear-eyed approach to see how cannabis affects chronic users in their everyday lives.鈥&nbsp;</p> <p>He adds the study isn鈥檛 an endorsement of heavy cannabis use, pointing out there is plenty of research highlighting its risks 鈥 especially among adolescents.&nbsp;</p> <p>Rather, he points to Statistics Canada data showing that nearly one in 10 adult Canadians are regular cannabis users, and they come from all walks of life. Cannabis is also the fourth most used recreational drug after caffeine, alcohol and tobacco. But despite its increased legal and social acceptance, relatively little is known about the everyday experiences of regular users. &nbsp;</p> <p>鈥淥ur data suggests that you can be hard-working, motivated and a chronic cannabis user at the same time.鈥&nbsp;</p> <p>The study received funding from the Social Sciences and Humanities Research Council of Canada.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Mon, 29 Apr 2024 17:51:28 +0000 rahul.kalvapalle 307652 at Waiting to inhale: 缅北强奸 researcher explores the link between cannabis laws and racial injustice /news/waiting-inhale-u-t-researcher-explores-link-between-cannabis-laws-and-racial-injustice <span class="field field--name-title field--type-string field--label-hidden">Waiting to inhale: 缅北强奸 researcher explores the link between cannabis laws and racial injustice</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2023-04/UofT5475_20120404_Akwasi-Owusu-Bempah_001.jpeg?h=19fdecb4&amp;itok=vNhtXZbw 370w, /sites/default/files/styles/news_banner_740/public/2023-04/UofT5475_20120404_Akwasi-Owusu-Bempah_001.jpeg?h=19fdecb4&amp;itok=By-p2qvG 740w, /sites/default/files/styles/news_banner_1110/public/2023-04/UofT5475_20120404_Akwasi-Owusu-Bempah_001.jpeg?h=19fdecb4&amp;itok=U6JB07gb 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2023-04/UofT5475_20120404_Akwasi-Owusu-Bempah_001.jpeg?h=19fdecb4&amp;itok=vNhtXZbw" alt="Akwasi Owusu-Bempah"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2023-04-13T15:35:29-04:00" title="Thursday, April 13, 2023 - 15:35" class="datetime">Thu, 04/13/2023 - 15:35</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p>(Photo by Brian Summers)</p> </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/tina-adamopoulos" hreflang="en">Tina Adamopoulos</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/our-community" hreflang="en">Our Community</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/black-research-network" hreflang="en">Black Research Network</a></div> <div class="field__item"><a href="/news/tags/institutional-strategic-initiatives" hreflang="en">Institutional Strategic Initiatives</a></div> <div class="field__item"><a href="/news/tags/cannabis" hreflang="en">Cannabis</a></div> <div class="field__item"><a href="/news/tags/crime" hreflang="en">Crime</a></div> <div class="field__item"><a href="/news/tags/u-t-mississauga" hreflang="en">缅北强奸 Mississauga</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>A new co-authored book by&nbsp;<strong>Akwasi Owusu-Bempah</strong>,<strong>&nbsp;</strong>an associate professor in the department of sociology at the University of Toronto Mississauga, examines how harsh cannabis laws have contributed to racial injustice 鈥 and how to repair the communities most affected.&nbsp;</p> <p><a href="http://mitpress.mit.edu/9780262047685/waiting-to-inhale/#:~:text=Waiting%20to%20Inhale%20illuminates%20the,and%20cannabis%20entrepreneurs%20who%20are"><em>Waiting to Inhale:&nbsp;Cannabis Legalization and the Fight for Racial Justice&nbsp;</em></a>illuminates how the war on drugs has disproportionally impacted Black and Indigenous communities in the United States through the stories of people who are on the front lines of advocacy.</p> <p>The book, which came out this week,&nbsp;was written with entrepreneur and cannabis industry leader Tahira Rehmatullah.

In Canada, Prime Minister Brian Mulroney initiated a national drug strategy in July 1982.&nbsp;</p> <p>But the criminalization of drug use and its history of systemically targeting racialized communities runs deeper.&nbsp;</p> <p>In the U.S.,&nbsp;<em>The Marihuana Tax Act&nbsp;</em>of 1937 made the possession or transfer of cannabis illegal. According to the University of Pennsylvania, a trillion dollars have been spent enforcing drug policy since 1971. By contrast, about a billion dollars have been spent in Canada. Meanwhile, cannabis legalization in Canada and globally is a multibillion-dollar industry.&nbsp;</p> <p>While discussions and political campaigns about cannabis legalization have largely focused on the positive societal and economic factors, it has in most cases failed to acknowledge the injustices of the war on drugs.&nbsp;</p> <p><em>Waiting to Inhale</em>&nbsp;personalizes the need for criminal justice reform in the U.S. through interviews with people who have served unjust cannabis convictions. Some are now dedicated to advancing cannabis amnesty, including&nbsp;Evelyn LeChapelle of Oakland, Calif., who was convicted in 2013 as a young mother. She&nbsp;spent 87 months in prison after a 2013 arrest for a small role in a cannabis distribution operation 鈥 despite having no previous criminal record. LaChapelle was released in 2018 and is now a social justice advocate and entrepreneur who offers employment to those with a similar story.&nbsp;</p> <p>The book also tells the story of Michael Thompson, who in&nbsp;received a prison sentence of 42 to 60 years for selling three pounds of cannabis to a friend&nbsp;鈥 and police informant 鈥 in Michigan in 1994. Thompson was incarcerated for 25 years until the recreational use of cannabis became legal in the state in 2018.&nbsp;<a href="https://www.metrotimes.com/weed/michael-thompson-opens-up-about-being-michigans-longest-serving-non-violent-offender-31457887">He was the longest-serving, non-violent offender in Michigan鈥檚 history</a>.&nbsp;</p> <p>鈥淲hen we look at the harsh penalties associated with the simple possession of cannabis in many U.S. states, they are much more consequential than other more serious crimes like financial fraud or even violent offenses,鈥 Owusu-Bempah says.&nbsp;</p> <h4>Canada&nbsp;and cannabis&nbsp;</h4> <p>While&nbsp;<em>Waiting to Inhale</em>&nbsp;focuses on the decriminalization of cannabis in the U.S, there are many parallels with Canada&nbsp;鈥&nbsp;a conversation Owusu-Bempah is leading.&nbsp;</p> <p>Owusu-Bempah is a member of&nbsp;Canada鈥檚&nbsp;<a href="https://www.justice.gc.ca/eng/cj-jp/cbjs-scjn/sg-gp.html">Black Justice Strategy</a>鈥檚 steering committee. Established to help reform Canada鈥檚 criminal justice system, the committee stems from a 2019 commitment from the federal government to address anti-Black racism and the over-representation of Black Canadians in federal prisons.&nbsp;</p> <p>The criminalization of cannabis in Canada can be traced to the 1920s when a moral panic was cultivated around its use, targeting Black and Indigenous populations. After a change in drug laws during the Mulroney administration, Black Ontarians experienced increased placement in the province鈥檚 correctional facilities.&nbsp;<a href="https://journals.sagepub.com/doi/full/10.1177/21533687211006461">According to a&nbsp;2021 report</a>, one in 15 young Black men in Ontario has experienced jail time, compared to nearly one in 70 young white men.&nbsp;</p> <p>Before legalization, Canadian youth had amongst the highest rates of cannabis use globally&nbsp;yet marginalized people are still most likely to be arrested for cannabis possession and use, Owusu-Bempah says.&nbsp;</p> <p>&nbsp;</p> <p><iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen frameborder="0" height="422px" src="https://www.youtube.com/embed/fh5tGuCsrPs" title="YouTube video player" width="750px"></iframe></p> <p>&nbsp;</p> <h4>Moving forward&nbsp;</h4> <p>In their book, Owusu-Bempah and Rehmatullah identify key action items to overturn racist policies and rebuild communities affected by cannabis criminalization.&nbsp;</p> <p>Owusu-Bempah says clearing the records of the convicted remains vital in reconciliation since opens avenues for employment. He adds that redistributing tax revenue generated from legal cannabis sales to reinvest in and revitalize neighbourhoods is also important.</p> <p>He would also like to see the legal industry create employment opportunities for people with cannabis convictions&nbsp;or other drug offences.&nbsp;</p> <p>鈥淲hat we want to see is space within this legal industry for those people who've been targeted by the war on drugs,鈥 Owusu-Bempah says.&nbsp;鈥淭he billions of dollars spent on police, courts and corrections were not spent on schools, hospitals, community centres&nbsp;and community health-care centres within those neighbourhoods.&nbsp;We highlight these possibilities [in the book].&nbsp;</p> <p>"At the most basic level, the criminal records of people who've been convicted of activities that are now no longer illegal should be cleared.鈥&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 13 Apr 2023 19:35:29 +0000 Christopher.Sorensen 301055 at Researcher explores use of cannabinoids to treat obesity /news/u-t-researcher-explores-use-cannabinoids-treat-obesity <span class="field field--name-title field--type-string field--label-hidden">Researcher explores use of cannabinoids to treat obesity</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2023-04/GettyImages-1056867134-crop.jpeg?h=afdc3185&amp;itok=E-GzWOUb 370w, /sites/default/files/styles/news_banner_740/public/2023-04/GettyImages-1056867134-crop.jpeg?h=afdc3185&amp;itok=gm6u_NU_ 740w, /sites/default/files/styles/news_banner_1110/public/2023-04/GettyImages-1056867134-crop.jpeg?h=afdc3185&amp;itok=G0_Q_do5 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2023-04/GettyImages-1056867134-crop.jpeg?h=afdc3185&amp;itok=E-GzWOUb" alt="person in lab coat and latex gloves handles a marijuana plant"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2022-01-04T09:29:24-05:00" title="Tuesday, January 4, 2022 - 09:29" class="datetime">Tue, 01/04/2022 - 09:29</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p>(Photo by Chris Roussakis/Bloomberg/Getty Images)</p> </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/gabrielle-giroday" hreflang="en">Gabrielle Giroday</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/our-community" hreflang="en">Our Community</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/institutional-strategic-initiatives" hreflang="en">Institutional Strategic Initiatives</a></div> <div class="field__item"><a href="/news/tags/temerty-faculty-medicine" hreflang="en">Temerty Faculty of Medicine</a></div> <div class="field__item"><a href="/news/tags/cannabis" hreflang="en">Cannabis</a></div> <div class="field__item"><a href="/news/tags/alumni" hreflang="en">Alumni</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp;

For my doctorate, I focused on sex and gender and how they impact cannabis use. For example, <a href="https://pubmed.ncbi.nlm.nih.gov/31637452/">I published a&nbsp;paper&nbsp;in 2019</a> looking at how smoking cannabis affected young adults of different sexes.</p> <p>Before this project, I was already very interested in investigating addiction to cannabis and looking at how cannabinoids can be used to treat substance use disorders.</p> <p>As for&nbsp;this current research, there are&nbsp;interesting parallels between obesity and overeating, and addiction or substance use disorders. Both involve harmful behavioural patterns that lead to excessive intake of food&nbsp;or psychoactive drugs. It鈥檚 a new area that deserves further exploration.</p> <p><strong>Can you explain your approach?</strong></p> <p>This research will include a randomized controlled trial that will look at if nabilone 鈥 a synthetic cannabinoid drug 鈥 can reduce body weight in adults with obesity.</p> <p>We are recruiting a sample of 60 people who have obesity and randomizing them to receive either a high dose of the drug nabilone,&nbsp;a low dose, or a placebo. Participants will be 25 to 45 years old.</p> <p>Nabilone will be taken as an oral capsule. It鈥檚 very similar to THC, which is the active component of cannabis, but it鈥檚 a little structurally different. The study participants will be taking nabilone daily over the course of 12 weeks.</p> <p>During that period, we鈥檒l be monitoring the patients鈥 body weight as well as other measures to see if there are any adverse effects of the nabilone.</p> <p>In the research, we鈥檙e not just trying to see if the cannabinoid drug can reduce body weight in adults who are obese, but we鈥檙e also trying to understand why. We鈥檒l do this by using neuroimaging, measuring changes in the gut microbiome, and measuring cannabinoids in the blood and different hormones.</p> <p>We鈥檙e also taking measures of participants鈥 brain activity at the baseline, before they enter treatment&nbsp;and at the end of the 12 weeks. Specifically, we鈥檙e interested in seeing how the neural response to food images changes over the course of treatment.</p> <p>We鈥檝e started recruiting participants to take part of the research, and we鈥檙e hoping to finish the trial in two years.</p> <p><strong>What do you hope to achieve through this work?</strong></p> <p>Nabilone is similar to THC. And we know cannabis actually is pro-appetite&nbsp;鈥&nbsp;in that it increases appetite. In the past, cannabis has been associated with 鈥渢he munchies鈥 and been used by people with wasting syndromes or who are having problems with appetite. So, on the surface, the research seems a bit paradoxical.</p> <p>But&nbsp;what my supervisor Le Foll and others have found&nbsp;is that people who use cannabis regularly actually have lower BMI, lower risk of obesity and a lower of risk of diabetes then people who don鈥檛 use cannabis.</p> <p>This research will be a first-in-human trial to see if administering nabilone will lead to a lower body weight in adults who are obese, which would replicate animal findings and which would be line with what we鈥檙e seeing in epidemiological data. We don鈥檛 know what we鈥檒l find yet.</p> <p><strong>How will you measure the effects of nabilone on each participant?</strong></p> <p>The endocannabinoid system 鈥 which is the body鈥檚 innate system that underlies the effects of cannabinoids 鈥 is a system that is very much involved in all sorts of brain processes such as our perceptions of pleasure and reward. So, we think it鈥檚 possible our research might find that nabilone reduces participants鈥 responses to food images, which is why we鈥檙e doing neuroimaging of participants鈥 brains.</p> <p>Plus, there is also an interesting relationship between cannabinoids and gut bacteria, so we want to measure the gut microbiome to see whether that changes with treatment.</p> <p>Research&nbsp;has found that people with obesity tend to have higher levels of endocannabinoids, which are the body鈥檚 own cannabinoid compounds.&nbsp;We believe that taking nabilone, or any cannabinoid drug, over a period of time might disrupt endocannabinoid levels, which could be one way that nabilone leads to a reduction in body weight.</p> <p><strong>How would you describe the field of cannabis or cannabinoid research these days?</strong></p> <p>I think cannabis and cannabinoid research has changed, especially after legalization. It鈥檚 definitely a really growing field and I feel lucky I entered the field when I did&nbsp;in 2015&nbsp;鈥 three years before legalization happened.</p> <p>I still think there鈥檚 still a lot of stigma around cannabis use. This affects the participants I work with, who often use cannabis or have a cannabis use disorder.&nbsp; Hopefully, with legalization, this will change.</p> <p>I think it鈥檚 a really exciting time to be doing cannabis research, especially because there are&nbsp;a lot of misconceptions. It seems to be a very polarizing topic. You have cannabis advocates who present it as a 鈥渃ure-all drug,鈥 and then you have prohibitionists, who argue it鈥檚 bad and harming people and should be illegal.</p> <p>To me, it鈥檚 somewhere in the middle. There are a lot of misconceptions in the research community and in the general public, which is why the field is so fascinating and why it鈥檚 where I want to take the rest of my career.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Tue, 04 Jan 2022 14:29:24 +0000 Christopher.Sorensen 301090 at 缅北强奸 researchers to study impact of cannabis on Indigenous oral health /news/u-t-researchers-study-impact-cannabis-indigenous-oral-health <span class="field field--name-title field--type-string field--label-hidden">缅北强奸 researchers to study impact of cannabis on Indigenous oral health</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/05-22-2018-KatiaTaylorPhotography-011.jpg?h=9a32df61&amp;itok=hFJZEFCE 370w, /sites/default/files/styles/news_banner_740/public/05-22-2018-KatiaTaylorPhotography-011.jpg?h=9a32df61&amp;itok=bHgY8xSF 740w, /sites/default/files/styles/news_banner_1110/public/05-22-2018-KatiaTaylorPhotography-011.jpg?h=9a32df61&amp;itok=SYASVX7n 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/05-22-2018-KatiaTaylorPhotography-011.jpg?h=9a32df61&amp;itok=hFJZEFCE" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2020-06-10T11:59:04-04:00" title="Wednesday, June 10, 2020 - 11:59" class="datetime">Wed, 06/10/2020 - 11:59</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Sacred objects at an Indigenous Learning Circle symposium at 缅北强奸's Faculty of Dentistry (photo by Katia Taylor)</div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/our-community" hreflang="en">Our Community</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/cannabis" hreflang="en">Cannabis</a></div> <div class="field__item"><a href="/news/tags/waakebiness-bryce-institute-indigenous-health" hreflang="en">Waakebiness-Bryce Institute for Indigenous Health</a></div> <div class="field__item"><a href="/news/tags/dalla-lana-school-public-health" hreflang="en">Dalla Lana School of Public Health</a></div> <div class="field__item"><a href="/news/tags/faculty-dentistry" hreflang="en">Faculty of Dentistry</a></div> <div class="field__item"><a href="/news/tags/indigenous" hreflang="en">Indigenous</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>A multidisciplinary team from the University of Toronto, with experts from the Faculty of Dentistry and the Waakebiness-鈥婤ryce Institute for Indigenous Health at the Dalla Lana School of Public Health has been awarded a five year, $1.5-million grant from the Canadian Institutes of Health Research to study the impact of cannabis use on the oral health of Indigenous populations.</p> <p>The researchers will work in partnership with Indigenous communities and public health authorities, including: Norway House Cree Nation (Kinosao Sipi Cree Nation) in northern Manitoba;

Let us hope that one of Health Canada鈥檚 New Year鈥檚 resolutions is to do a better job of regulating cannabis and protecting the public, and in particular youth, from harm.</p> <p>Cannabis edibles offer a lucrative opportunity for licensed cannabis producers and retailers in both the medical and recreational market. However, while governments and businesses move to meet public demand and their bottom lines, there is a need to acknowledge the inherent risks cannabis, and in particular edibles, can pose.</p> <p>While edibles may provide a delivery system that provides the intoxicating effects of cannabis while avoiding the risks of smoking, the delayed and variable absorption of cannabis edibles can <a href="http://dx.doi.org/10.5811/westjem.2015.3.25284">result in over-consumption and unpredictable results</a>.</p> <p>As both an addiction medicine and family physician, I have seen many adolescents whose cannabis use has negatively affected their mood, motivation, sleep and ability to simply function.</p> <h3>Substantial harm to youth</h3> <p>The intoxicating effects of cannabis when taken orally can be delayed up to 90 minutes, peaking a few hours later, and may <a href="https://doi.org/10.2165/00003088-200342040-00003">last for several hours</a>. Aside from the expected diminished concentration, decreased executive functioning and impaired memory, acute cannabis toxicity can present as severe anxiety, panic attacks, nausea, delirium or psychosis.</p> <p>In Colorado, where cannabis sales were legalized for people 21 and older in 2012, <a href="https://dx.doi.org/10.1001%2Fjama.2014.17057">edible products are the major cause of cannabis intoxication</a>. Emergency room visits and hospitalizations due to <a href="https://dx.doi.org/10.5811%2Fwestjem.2019.4.39935">adverse reactions from cannabis edibles have increased in Colorado since legalization</a>, and adolescent visits rose to <a href="https://doi.org/10.1016/j.jadohealth.2017.12.010">4.9 per 1,000 visits in 2015</a> from 1.8 per 1,000 visits in 2009.</p> <p>It鈥檚 true that often these symptoms are temporary and that a cannabis overdose likely <a href="https://doi.org/10.1002/cbdv.200790151">won鈥檛 kill someone</a>, but it can cause significant mental and physical disability.</p> <p>During the early phase of cannabis legalization in Oregon and Alaska, 253 overdoses 鈥 some requiring stays in the intensive care unit and including one death 鈥 were reported to poison centres over a 16-month period: Seventy-one&nbsp;individuals were under the age of 12&nbsp;and 42 <a href="https://www.ncbi.nlm.nih.gov/pubmed/30676820">were between the ages of 12 and 17</a>. The median age was only 20 years old.</p> <p>Beyond the risks of acute toxicity, cannabis use that starts in adolescence has been linked to a variety of harms, including <a href="http://doi.org/10.1001/jamapsychiatry.2018.4500">depression, suicidality</a>, <a href="https://dx.doi.org/10.1056%2FNEJMra1402309">psychosis</a> and <a href="https://dx.doi.org/10.5811%2Fwestjem.2019.4.39935">schizophrenia</a>. Considering that Canadian youth are <a href="https://www.theglobeandmail.com/news/national/canadian-teens-lead-developed-world-in-cannabis-use-unicef-report/article11221668/">the highest adolescent users in the world</a> and that they believe, <a href="https://doi.org/10.1503/cmaj.191217">despite strong scientific evidence to the contrary</a>, that cannabis will improve their mood, anxiety and sleep, there are significant challenges in protecting them from potential cannabis-related harms.</p> <h3>Intoxicants aren鈥檛 candy</h3> <p>Unfortunately, Health Canada has allowed troublingly high THC concentrations (<a href="https://www.canada.ca/en/health-canada/services/drugs-medication/cannabis/laws-regulations/regulations-support-cannabis-act.html">up to 30 per cent in some cases</a>) in dried cannabis products. While many edibles will be purchased directly from retailers, edibles made at home may have higher THC concentrations.</p> <p>Health Canada has also done little to rein in misleading advertising by the cannabis industry.&nbsp;It has allowed licensed producers to <a href="https://www.cfp.ca/content/cfp/65/12/864.full.pdf">make unsubstantiated claims about the medicinal value of cannabis</a>, which only further contributes to positive adolescent social attitudes towards cannabis.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/310572/original/file-20200116-181598-1gzdhxs.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img alt sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" src="https://images.theconversation.com/files/310572/original/file-20200116-181598-1gzdhxs.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" srcset="https://images.theconversation.com/files/310572/original/file-20200116-181598-1gzdhxs.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=399&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/310572/original/file-20200116-181598-1gzdhxs.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=399&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/310572/original/file-20200116-181598-1gzdhxs.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=399&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/310572/original/file-20200116-181598-1gzdhxs.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=501&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/310572/original/file-20200116-181598-1gzdhxs.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=501&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/310572/original/file-20200116-181598-1gzdhxs.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=501&amp;fit=crop&amp;dpr=3 2262w"></a> <figcaption><span class="caption">Chocolates with marijuana will be widely available as edible products are introduced to the market (photo via Shutterstock)</span></figcaption> </figure> <p>While Health Canada <a href="https://www.canada.ca/en/health-canada/services/cannabis-regulations-licensed-producers/packaging-labelling-guide-cannabis-products/guide.html#a51">does not permit direct advertising of cannabis</a> and requires plain packaging and warnings on all cannabis products, the cannabis industry is able to market through media stories and their websites.</p> <p>The Ontario Cannabis Store, a Crown corporation, <a href="https://ocs.ca/blogs/facts-about-cannabis-consumption/what-are-edibles">has a picture of chocolate squares to advertise edibles on their website</a> and is set to roll out more than 50 new edible and vape products this week.

In Colorado, <a href="http://www.cannabisconsumer.org/uploads/9/7/9/6/97962014/2014_med_annual_report_1.pdf">edibles accounted for 45 per cent of all sales by 2014</a>. Health Canada鈥檚 packaging guidelines and dose limits for edibles (<a href="https://www.canada.ca/en/health-canada/services/drugs-medication/cannabis/resources/regulations-edible-cannabis-extracts-topicals.html">10 milligrams per item</a>) will only go so far in mitigating potential harms.</p> <p>Health Canada has vaguely stated that the products should not be appealing to youth, but it is hard to imagine that chocolates and flavoured drinks with names like 鈥<a href="https://ocs.ca/search?product=4350458627916&amp;q=gummies">Pineapple Orange Gummies</a>鈥 would not be enticing to that population.</p> <p>A more concerted public health campaign and detailed warnings on products are needed. Targeting successful cannabis education to youth is a challenging task but an imperative one.</p> <p>While the Supreme Court of Canada ruled to give Canadians legal access to cannabis, Health Canada now bears the regulatory and educational responsibility. In 2018, <a href="https://nationalpost.com/news/health-canadas-marijuana-education-campaign-nuanced-expert-says">Health Canada committed a little over $100 million over six years for public cannabis education and surveillance</a>. But $186 million in taxes&nbsp;<a href="https://business.financialpost.com/cannabis/cannabis-business/governments-raked-in-186-million-in-taxes-on-cannabis-trade-in-first-five-months-of-legalization">were collected in the first five months</a> of legalization. Health Canada could and should invest so much more into oversight and education. The collective health of our youth depends upon it.<br> <!-- End of code.

Extrapolating from the CAMH results, the researchers suggest about 827,000 people in multi-unit dwellings were exposed to cannabis smoke from hallways, other units or elsewhere in their building&nbsp;鈥 as opposed to about 728,000 who smelled tobacco smoke.</p> <p><img class="migrated-asset" src="/sites/default/files/MChaiton.png" alt>鈥淚 was surprised there were more reports of cannabis than tobacco,鈥 says co-author <strong>Michael Chaiton </strong>(pictured left), an associate professor in the Dalla Lana School of Public Health. 鈥淲e鈥檝e known anecdotally there had been increasing calls and complaints about cannabis smoke, but we hadn鈥檛 been able to quantify it until now.鈥<br> &nbsp;</p> <p>Chaiton hopes the&nbsp;results will contribute to the debate over whether to regulate cannabis like alcohol,&nbsp;by forbidding its consumption in public spaces,&nbsp;or like tobacco, by prohibiting its use in indoor public spaces or near buildings.</p> <p>He and his co-authors <strong>Alanna Chu</strong>&nbsp;and <strong>Pamela Kaufman</strong>, an assistant professor at Dalla Lana, <a href="https://www.mdpi.com/1660-4601/16/18/3332/htm">published their study on Sept. 10</a> in the <em>International Journal of Environmental Research and Public Health</em>.&nbsp;</p> <p>The team has been tracking exposure to tobacco smoke in residential buildings for many years, and recently they have become increasingly concerned about cannabis second-hand smoke.</p> <p>Despite the surprising results, Chaiton says it鈥檚 very possible that the study underreported cannabis exposure, since the authors found people who consume cannabis themselves were more likely to report smelling it 鈥 suggesting that not everybody can identify cannabis by its pungent scent.&nbsp;&nbsp;</p> <p>The study, the first to examine the prevalence of involuntary cannabis exposure in residential buildings, also showed that people of lower income, who more often live in multi-unit buildings, are at higher risk of exposure to second-hand smoke and any related health effects from other people鈥檚 cannabis use.&nbsp;</p> <p>But those health effects are not yet fully clear.</p> <p>Third-hand smoke, the residue from smoke that clings to walls and furniture or&nbsp;settles in dust, is a particular concern for tobacco because nicotine is sticky and accumulates easily on surfaces like drapery, clothing and furniture.</p> <p>But Chaiton says researchers don鈥檛 yet know whether cannabis travels&nbsp;the same way through apartment buildings, including ventilation systems, or how it contributes to third-hand smoke contamination.&nbsp;</p> <p>The next step is to determine whether exposure reports have increased since the legalization of cannabis in October 2018.</p> <p>鈥淚f there are more people smoking cannabis or smoking more freely, indoor use in buildings may increase,鈥 Chaiton says. 鈥淏ut, on the other hand, people may be more willing to go outside, lessening second-hand exposure indoors. As well, people may be less likely to report it to surveyors because it鈥檚 legal 鈥&nbsp;or they may be more likely to complain if they have less fear of repercussions.鈥</p> <p>Funding for the study was provided by the Canadian Institutes for Health Research and the Ontario Ministry of Health and Long-Term Care.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Fri, 13 Sep 2019 14:50:49 +0000 geoff.vendeville 158247 at 缅北强奸 expert on why cannabis legalization must include cannabis equity /news/u-t-expert-why-cannabis-legalization-must-include-cannabis-equity <span class="field field--name-title field--type-string field--label-hidden">缅北强奸 expert on why cannabis legalization must include cannabis equity</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2019-05-16-conversation-cannabis-resized.jpg?h=afdc3185&amp;itok=Tq5D2rQg 370w, /sites/default/files/styles/news_banner_740/public/2019-05-16-conversation-cannabis-resized.jpg?h=afdc3185&amp;itok=C681Xmqg 740w, /sites/default/files/styles/news_banner_1110/public/2019-05-16-conversation-cannabis-resized.jpg?h=afdc3185&amp;itok=p4XjnhDh 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2019-05-16-conversation-cannabis-resized.jpg?h=afdc3185&amp;itok=Tq5D2rQg" alt="Photo of pro-cannabis gathering"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>noreen.rasbach</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2019-05-16T14:50:00-04:00" title="Thursday, May 16, 2019 - 14:50" class="datetime">Thu, 05/16/2019 - 14:50</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">A flag is flown during the annual marijuana 420 gathering in Toronto (photo by Nathan Denette/The Canadian Press)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/akwasi-owusu-bempah" hreflang="en">Akwasi Owusu-Bempah</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/city-culture" hreflang="en">City &amp; Culture</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/cannabis" hreflang="en">Cannabis</a></div> <div class="field__item"><a href="/news/tags/diversity" hreflang="en">Diversity</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp; Innovation</a></div> <div class="field__item"><a href="/news/tags/conversation" hreflang="en">The Conversation</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p><span></span>Canada鈥檚 federal government is currently working to pass a bill that would provide <a href="https://www.theglobeandmail.com/cannabis/article-amnesty-program-for-canadians-convicted-of-simple-cannabis-possession/">pardons for people convicted of minor cannabis possession</a>.

What Canadian legalization still lacks, however, are <a href="https://www.hilltimes.com/2018/01/22/cannabis-legalization-canada-case-pardons-preferential-licencing/130906">the important measures needed to repair the damage caused by almost a century of prohibition</a>.</p> <p>American legislators should take note.</p> <p>As is the case in <a href="https://doi.org/10.1177/1362480616677493">many other jurisdictions</a>, Canadian drug law enforcement is heavily racialized. Data gathered from <a href="https://www.thestar.com/news/insight/2017/07/06/toronto-marijuana-arrests-reveal-startling-racial-divide.html">Toronto</a> and other major <a href="https://news.vice.com/en_ca/article/d35eyq/black-and-indigenous-people-are-overrepresented-in-canadas-weed-arrests">Canadian cities</a> show that Black and Indigenous people have been arrested for minor cannabis possession at rates as high as five and nine times that of whites, respectively.</p> <p>This means that <a href="https://theconversation.com/as-cannabis-is-legalized-lets-remember-amnesty-103419">Black and Indigenous people have been disproportionately burdened</a> with the outcomes of a criminal record 鈥 reduced educational and employment opportunities, poorer housing prospects and travel restrictions 鈥 for engaging in an activity enjoyed by a significant proportion of the Canadian population.</p> <p><iframe allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen frameborder="0" height="422" src="https://www.youtube.com/embed/3zhuo3aizOY" width="754"></iframe></p> <p><em>Akwasi Owusu-Bempah presented a TEDx talk, The Untapped Promise of Cannabis Legalization, as part of its Mississauga series</em></p> <h3>A lesson for the United States</h3> <p>Unlike the narrative now dominant among the U.S. <a href="https://www.nytimes.com/2019/03/17/us/politics/marijuana-legalize-democrats.html">2020 Democratic</a> hopefuls, Canada鈥檚 move towards legalization was never about social justice or reparations. Having promised recreational cannabis as part of his campaign platform, Prime Minister Justin Trudeau鈥檚 government rushed to draft and pass <a href="https://laws-lois.justice.gc.ca/eng/acts/c-24.5/">the Cannabis Act</a> in time to help them secure a political win.</p> <p>Addressing the racialized harms of cannabis prohibition barely featured in political debates over legalization in Canada. Instead, the focus was on promoting public health and diverting profits away from the illicit market.<b><i>&nbsp;</i></b></p> <p>While we dither over whether to provide pot pardons, equally substantive equity measures 鈥 such as the <a href="https://youtu.be/3zhuo3aizOY">reinvestment of cannabis tax revenue into the communities most harmed by prohibition</a>&nbsp;and the incorporation of the drug war鈥檚 victims into the legal cannabis industry 鈥 go largely unrealized. For legalization to be a true success, these measures must be forthcoming.</p> <p>Opponents were right to <a href="https://www.leafly.com/news/politics/how-the-cannabis-industry-defeated-legalization-in-new-york">derail legalization in New York state last month</a> because the proposed bill failed to adequately address social justice issues up front.</p> <p>Given the nature of the political process, it can be all too easy for politicians to satisfy themselves with half-baked policies. If there is one thing that American lawmakers can learn from the Canadian example, it is that cannabis equity must be incorporated into legalization from the outset.</p> <p>Given the lack of <a href="https://www.forbes.com/sites/amymargolis/2018/09/20/the-top-cannabis-companies-are-dominated-by-men/#63b3bc50565e">racial and economic diversity</a> in established cannabis industries, not doing so is likely to further entrench the <a href="https://www.nytimes.com/2018/04/19/opinion/boehner-marijuana-blacks-prison.html">inequalities created</a> by the war on drugs.<!-- Below is The Conversation's page counter tag.

TC3 combines the research muscle of the university with a dozen academic hospitals.</p> <p>鈥淭here is a huge research engine at 缅北强奸,鈥 said <strong>Ruth Ross</strong>, a professor and chair of the Faculty of Medicine鈥檚 pharmacology and toxicology department and a member of the TC3 steering committee.</p> <p>More than 50 principal investigators are already members of TC3, which is focused on how cannabis and cannabinoids work, clinical research and public health.</p> <p>鈥淲e鈥檙e hoping the consortium will spark multi-level collaboration across these three pillars, and we鈥檒l get information into the hands of the public, government and health officials as quickly as possible,鈥 Ross told Thursday鈥檚 Cannabis Innovation Summit.</p> <p>Medical marijuana has been legal in Canada for almost 20 years, and recreational cannabis since October.&nbsp;Edible cannabis products will become legal in the fall&nbsp; and there is also a whole new area of exposure emerging around cannabidiol (CBD).</p> <p>The summit heard that research on both the potential benefits and risks is lagging.</p> <p>Adding to the challenge is the fact 140 different cannabinoid compounds have so far been identified in cannabis.</p> <p>鈥淐annabis is not a single substance, and if you take any of the literature that is published on cannabis, I can invalidate 99 per cent of it simply because nobody identifies the substances properly,鈥 said <strong>Lakshmi Kotra</strong>, a 缅北强奸 professor at the Leslie Dan Faculty of Pharmacy and a TC3 steering committee member.</p> <p>Kotra shared an anecdote about collecting 186 samples of medical cannabis from patients and testing them all in his lab. 鈥淣o two samples were the same.鈥</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__10611 img__view_mode__media_large attr__format__media_large" height="453" src="/sites/default/files/2019-04-08-summit-embed-resized.jpg" typeof="foaf:Image" width="680" loading="lazy"></p> <p><em>One of the panels at Thursday鈥檚 summit looked at the societal issues of cannabis (photo by Jim Oldfield)</em></p> <p>The summit heard a range of concerns from researchers about potential harms from cannabis use, including the impact of second-hand smoke, the effects on pregnant women and their fetuses, and altered brain chemistry in young adults and adolescents.</p> <p>But investigators indicated they were&nbsp;also inspired by the tantalizing hints of potential benefits from cannabis in all its variations.</p> <p>The list of potential benefits with at least some scientific validation includes chronic pain, epilepsy, MS, depression, anxiety, chemo-related nausea, autism, PTSD, Tourette syndrome and glaucoma, as well as some aspects of Alzheimer鈥檚.</p> <p>鈥淐annabis clearly works in epilepsy,鈥 said <strong>Mac Burnham,</strong> a 缅北强奸 professor emeritus and co-director of the Epilepsy Research Program at the Ontario Brain Institute.</p> <p>Burnham wants to focus on treatment ratios between CBD and THC 鈥 the principal psychotropic in cannabis 鈥 because patients say they work better together. But he had to stop his experiments because of delays in getting a licence from Health Canada.</p> <p>Scientists at the summit were cautioned to guard against their research becoming tainted by perceived bias or influence, especially by tobacco and alcohol companies that are moving into cannabis.</p> <p>鈥淲e have to be careful to protect our independence,鈥 said Dr. <strong>Bernard Le Foll</strong>, a professor at the Institute of Medical Science who is also on the TC3 steering committee. But he added that in some cases involving medical cannabis research, there are partnerships with pharmaceutical companies that are 鈥渂eneficial and appropriate.鈥</p> <p>The summit was told the need for research is growing along with the scope of the potential public health aspect. Approximately 10 per cent of Canadians have consumed cannabis in the last year and 40 per cent have used it at some point.</p> <p>CBD&nbsp;was singled out for the particular concern around the lack of understanding about&nbsp; how it works.</p> <p>鈥淲e really need to know what are the risks associated with its use,鈥 said Dr. <strong>Romina Mizrahi</strong>, an associate&nbsp;professor in the departments of psychiatry, pharmacology and toxicology and the Institute of Medical Science&nbsp;who focuses on youth mental health and addiction.</p> <p>鈥淎necdotally, we have seen an increase of patients with psychosis coming into the clinic using CBD for treatment,鈥 said Mizrahi,&nbsp;a TC3 steering committee member.</p> <p>About nine per cent of users develop cannabis dependency, but society has to balance those harms against opioids, said Daniele Piomelli of the University of California, Irvine, the keynote speaker at the summit.</p> <p>鈥淐annabis can cause acute toxicity but there is no evidence of lethality, even after decades and decades of use.鈥</p> <p>He also said research suggests the human body 鈥 which has its own&nbsp;endocannabinoid system 鈥 could one day be stimulated to enhance such things as energy levels, mood regulation and pain reduction, the same way cannabis seems to.</p> <p>鈥淲e could use our own cannabinoid system to achieve the same effect, and that would be better than administering THC,鈥 said Piomelli.</p> <p>&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Mon, 08 Apr 2019 18:03:46 +0000 noreen.rasbach 156148 at
