Overbaked: assessing and predicting acute adverse reactions to Cannabis.

Background: Trends toward legalizing cannabis may increase experimentation with the drug among less experienced users with limited knowledge of possible adverse reactions. This study explores the prevalence, frequency, and levels of distress produced by various acute adverse reactions to cannabis, as well as predictors of these reactions.

Methods: The Adverse Reactions Scale (ARS) was created and administered to a large sample of undergraduate college students (n = 999) who were predominantly white (> 70%), female (> 70%), recreational (> 90%) cannabis users.

Acute Effects of Cannabis on Symptoms of Obsessive-Compulsive Disorder.

Background: Little is known about the the acute effects of cannabis on symptoms of OCD in humans. Therefore, this study sought to: 1) examine whether symptoms of OCD are significantly reduced after inhaling cannabis, 2) examine predictors (gender, dose, cannabis constituents, time) of these symptom changes and 3) explore potential long-term consequences of repeatedly using cannabis to self-medicate for OCD symptoms, including changes in dose and baseline symptom severity over time.

Method: Data were analyzed from the app Strainprint® which provides medical cannabis patients a means of tracking changes in symptoms as a function of different doses and strains of cannabis across time.

Symptoms of obsessive-compulsive disorder predict cannabis misuse.

Introduction: Cannabis use has been linked to many psychological disorders. There is, however, a paucity of research investigating the link between cannabis use and obsessive-compulsive disorder (OCD). The present study sought to examine this link by exploring associations between severity of OCD symptoms, cannabis use, and cannabis misuse; determining whether these associations exist above and beyond symptoms of anxiety, depression, and stress; and testing the mediating role of cannabis coping motives (i.
