Cannabis shows potential for treating PTSD: New study
Substance use, including cannabis use, is common among trauma survivors. It’s easy to write off the drug as just a tool to briefly escape negative feelings, at the risk of worsening longer-term symptoms. However, the relationship between cannabis and PTSD is more complex than it appears on the surface. Study in this article.
Does cannabis use modify the effect of post-traumatic stress disorder on severe depression and suicidal ideation? Evidence from a population-based cross-sectional study of Canadians
This study provides preliminary epidemiological evidence that cannabis use may contribute to reducing the association between post-traumatic stress disorder and severe depressive and suicidal states. There is an emerging need for high-quality experimental investigation of the efficacy of cannabis/cannabinoids for the treatment of post-traumatic stress disorder. Study in this article.
Non-medical cannabis in North America: an overview of regulatory approaches
Although North American approaches to regulating recreational cannabis use are consistent in many aspects, some exceptions exist (e.g., home growing, personal possession). More research is needed to assess the impact of variations in regulatory policies on potential harms from legalization to inform future policy decisions in North America and abroad. Study in this article.
The impact of plain packaging and health warnings on consumer appeal of cannabis products. Compared to plain packaging or a brand logo, packages with full branding were considered more appealing and more likely to be youth-oriented (p < 0.001). Products with health warnings were considered less appealing than packages without warnings (p < 0.001). Edible gummies were perceived as more appealing and more likely to be youth-oriented than pre-rolled joints and cannabis oil (p < 0.001). Additionally, edible gummies were rated as significantly more appealing by 16–18 and 19–35-year-olds than by older adults (p < 0.02 for all). Study in this article.
Examining the association between exposure to various screen time sedentary behaviours and cannabis use among youth in the COMPASS study
The associations between frequency of cannabis use and various measures of STSBs suggest that screen time may be a risk factor for cannabis use among youth. This association may be mediated by youths’ mental wellbeing, given emerging evidence that STSB is a risk factor for poor mental health, and the tendency for individuals to use substances as a coping mechanism. Study in this article.
How Cannabis Alters Sexual Experience: A Survey of Men and Women
Many participants in our study found that cannabis helped them relax, heightened their sensitivity to touch, and increased intensity of feelings, thus enhancing their sexual experience, while others found that cannabis interfered by making them sleepy and less focused or had no effect on their sexual experience. Study in this article.
Cannabis use and physical activity among 89,777 adolescents aged 12-15 years from 21 low- and middle-income countries.
The overall prevalence of past (i.e., in lifetime but not in past 30 days) and current (in past 30 days) cannabis use were 1.0% and 2.9% respectively, while the prevalence of adequate PA in the past week (7 days/week of 60 min of PA) was 16.6%. The prevalence of adequate levels of PA in past and current cannabis use was 7.3% and 6.9%, respectively. Current and past cannabis use (vs. never) were associated with a significant 0.62 (95% CI = 0.41-0.94) and 0.43 (95%CI = 0.30-0.63) times lower odds for achieving adequate levels of PA, respectively. Study in this article.
The role of cannabis in treating anxiety: an update.
In reviewing recent evidence, we observed significant inconsistencies across findings from preclinical studies. Large-scale surveys suggest that cannabis may be effective in reducing anxiety, however, these results stand in contrast to equivocal findings from clinical trials. Study in this article.
Characterization of mental health in cannabis dispensary users, using structured clinical interviews and standardized assessment instruments.
Lifetime prevalence of mental illness in this cohort was high, and a large proportion of subjects endorsed psychological symptoms. The proportion of subjects who met criteria for classification of a current psychiatric disorder was low for mood disorders, but high for anxiety disorders and substance abuse/dependence. Cannabis use differed between the main psychiatric conditions. Study in this article.

To keep legal cannabis sales rising, prices must drop
Health Canada’s numbers indicate that the volume of dry cannabis sold rose 10 per cent to 12,917 kg. Oil volumes similarly climbed 14 per cent to 11,705 litres. Oil’s jump was largely due to a rebound in the sale of medical marijuana, which had slid in the two previous months. The recovery might partly represent customers leaving CannTrust in July and finding new medical suppliers in August.

Contrary to expectations, CUD prevalence decreased significantly across all ages reporting daily/almost daily cannabis use between 2002–2016. Cannabis dependence prevalence decreased for adolescents and young adults and was stable only among adults ages 26+ reporting daily/almost daily cannabis use.

Motives Matter: Cannabis use motives moderate the associations between stress and negative affect
While cannabis may provide temporary relief from symptoms of stress, depression, and anxiety, using cannabis to cope may be related to higher levels of depression, and use of cannabis for expansion and conformity may be related to higher levels of anxiety.
Attentional bias, craving and cannabis use in an inpatient sample of adolescents and young adults diagnosed with cannabis use disorder: The moderating role of cognitive control
CUD patients did not show an AB towards cannabis-related words. Session-induced cannabis craving was positively related to daily cannabis use, however not to the severity of CUD. Cognitive control did not moderate the relationships between AB/craving and the severity of CUD or daily cannabis use.
Online personalized feedback intervention for cannabis-using college students reduces cannabis-related problems among women
Tested a problem-focused online personalized feedback intervention (PFI). There was no main effect of condition on follow-up cannabis use. Gender moderated the relationship between condition and follow-up problems. Women in the PFI condition reported fewer problems than women in the control condition. Cannabis PFIs may reduce cannabis use-related problems among women (not men).
Urinary Pharmacokinetic Profile of Cannabinoids Following Administration of Vaporized and Oral Cannabidiol and Vaporized CBD-Dominant Cannabis
Urinary concentrations of CBD were higher after oral (mean Cmax: 776 ng/mL) versus vaporized CBD (mean Cmax: 261 ng/mL). CBD concentrations peaked 5 h after oral CBD ingestion and within 1 h after inhalation of vaporized CBD. After pure CBD administration, only 1 out of 218 urine specimens screened positive for ∆9-THCCOOH (20-ng/mL IA cutoff) and no specimens exceeded the 15-ng/mL confirmatory cutoff. After inhalation of CBD-dominant cannabis vapor, nine samples screened positive at the 20-ng/mL IA cutoff, and two of those samples screened positive at the 50-ng/mL IA cutoff. Four samples that screened positive (two at 20 ng/mL and two at 50 ng/mL) confirmed positive with concentrations of ∆9-THCCOOH exceeding 15 ng/mL.

Pot or not? Busts highlight growing confusion over hemp
The CBD craze is leaving the war on drugs a bit dazed and confused. The extract that’s been showing up in everything from candy to coffee is legally derived from hemp plants, which look and smell an awful lot like that other cannabis — marijuana. They’re so similar, police officers and the field tests they use on suspected drugs sometimes can’t tell the difference.
