Event Description
This month’s journal club will examine a landmark randomized controlled crossover trial exploring how smoked cannabis affects alcohol craving and consumption under controlled laboratory conditions. With the rise of THC beverages, “Cali sober” trends, and increasing co-use of cannabis and alcohol, this study provides some of the strongest causal evidence to date on whether THC increases or decreases drinking. We will review the study’s design, outcomes, and implications for clinical practice, harm-reduction counseling, and public health messaging.
