Although Canada legalized cannabis beverages in 2019, most available research on acute cannabis intoxication derives from dried flower and edible products. The distinct bioavailability and pharmacokinetic properties of phytocannabinoids ingested from beverages, however, contribute to significantly different acute and long-term effects that need to be better understood to ensure consumer safety....

Novel cannabinoids require systematic research to inform policies and practices. There is a growing interest in semi-synthetic cannabinoids by consumers, manufacturers, and regulators. However, there is a scarcity of research on these substances. Online discussion forums can provide guidance for research questions when current knowledge is scarce. The current project investigates the topics and...

Cannabis is increasingly accessible and use is increasing rapidly among older adults as laws change and cannabis becomes more frequently prescribed in healthcare settings. Past research identified cognitive effects of cannabis use among adolescents and young adults that can persist for several weeks after intoxication, though little is known about how these effects generalize to older adults....

Psychedelic-assisted psychotherapy has established antidepressant effects. Cannabis users appear to expect high doses administered in a session much like psychedelic-assisted psychotherapy to create comparable subjective effects. The current studies explored expectations of antidepressant effects of such cannabis-assisted sessions to replicate and extend previous work. Users not only expected a...

Links between cannabis use and psychosis generate research and media attention. Cannabis users have outscored non-users on the Schizotypal Personality Questionnaire-Brief (SPQ-B) in multiple studies, but previous work suggests that groups do not differ if biased items are removed. The present study examined links between schizotypal personality and cannabis use in a large sample recruited from...

Objective. Some adverse cannabis effects are greater in individuals on the psychosis spectrum compared to healthy individuals. We have previously reported that smoked cannabis acutely worsened psychotic-like states and reduced cognitive performance selectively in cannabis users at clinical high-risk (CHR) for psychosis. The objective of the present study was to further investigate the acute...
