Background: As of November 8, 2023, 24 states and the District of Columbia have legalized cannabis for both recreational and medical use (RMCL-states), 14 states have legalized cannabis for medical use only (MCL-states) and 12 states have no comprehensive cannabis legislation (NoCL-states). As more states legalize cannabis for recreational use, it is critical to understand the impact of such policies on driving safety.
Methods: Using the 2019 and 2020 Fatality Analysis Reporting System data, we performed multivariable logistic regression modeling to explore the association between state level legalization status and cannabis positivity using toxicological testing data for 14,079 fatally injured drivers. We performed a sensitivity analysis by including multiply imputed toxicological testing data for the 14,876 eligible drivers with missing toxicological testing data.
Results: Overall, 4702 (33.4%) of the 14,079 fatally injured drivers tested positive for cannabis use. The prevalence of cannabis positivity was 30.7% in NoCL-states, 32.8% in MCL-states, and 38.2% in RMCL-states (p < 0.001). Compared to drivers fatally injured in NoCL-states, the adjusted odds ratios of testing positive for cannabis were 1.09 (95% confidence interval: 0.99, 1.19) for those fatally injured in MCL-states and 1.54 (95% confidence interval: 1.34, 1.77) for those fatally injured in RMCL-states. Sensitivity analysis yielded similar results.
Conclusions: Over one-third of fatally injured drivers tested positive for cannabis use. Drivers fatally injured in states with laws permitting recreational use of cannabis were significantly more likely to test positive for cannabis use than those in states without such laws. State medical cannabis laws had little impact on the odds of cannabis positivity among fatally injured drivers.

Background: Evidence supporting cannabis substitution along with liberalized cannabis laws have left recovery homes such as sober living houses (SLHs) in a difficult position regarding policies relating to cannabis use among SLH residents. Moreover, there are few studies of cannabis use among SLH residents that can be used to inform cannabis use policies. Here we assess whether cannabis is related to alcohol use among SLH residents.

Marijuana poisoning in canines is still considered a taboo topic. Poisoning in pets is becoming increasingly common, in many cases resulting in severe clinical signs, such as ataxia, urinary incontinence, mydriasis, depression, and hyperesthesia. Colombia does not have any reliable test for the diagnosis of exposure to cannabis in animals, and it is not an obligation to report this kind of poisoning to the authorities.

Objective: Previous research has found that momentary positive affect precedes alcohol use, whereas results have been more mixed for negative affect.
Method: This study replicates and builds upon this literature by using a heavy drinking sample, half lesbian, gay, bisexual, trans, queer/questioning, and other minoritized sexual and gender identities (LGBTQ+) individuals.
Results: This study found that positive affect was related to subsequent alcohol use, but the relation was weaker for LGBTQ+ individuals compared to cisgender-straight individuals.

Background: People exposed to fentanyl may report that the dose of methadone in the commonly accepted therapeutic range feels too low. We examined self-reported methadone dose adequacy.
Methods: We conducted a retrospective cohort study of individuals prescribed methadone at a dose of at least 60mg daily using data from three community-recruited prospective cohort studies of people who use drugs in Vancouver, Canada from December 2016 through March 2020.
