Perspectives on cannabis risks and harm reduction among youth in Early Psychosis Intervention programs: a qualitative study

Purpose: The Canadian government legalized cannabis in 2018 and funded harm reduction campaigns to educate youth about the risks. Cannabis can contribute to psychosis in vulnerable populations, and consumption is common among youth in Early Psychosis Intervention (EPI) programs. The purpose of this study is to understand the views of youth in EPI programs on the risks related to cannabis and methods to reduce those risks. Design/methodology/approach A qualitative design and thematic analysis were used to understand the perspectives of youth in EPI programs (n = 15) towards cannabis risks and harm reduction.

Findings: Participants associated Δ−9 tetrahydrocannabinol (THC) with problems related to cognition, psychosis, respiration, addiction, motivation, finances, relationships and anxiety. Cannabidiol (CBD) was believed to be safe and risk-free. To reduce the risks associated with THC, participants suggested using in moderation, delaying use, using CBD over THC, accessing legal sources, avoiding high THC dosages and using non-combustible methods. Research limitations/implications Participants self-selected to participate, were psychiatrically stable and may not represent youth in EPI programs with more severe psychotic symptoms. Practical implications Assessing risk perceptions, motives for use and perspectives towards the cannabis and psychosis connection can reveal educational needs. CBD may offer a harm reduction option for EPI clients wanting to decrease THC intake, though more research is needed and adverse effects should be explained. Educational campaigns should disseminate the connection between cannabis and psychosis to facilitate early intervention. Originality/value This study adds to the literature by highlighting knowledge of harm reduction methods and gaps in risk awareness among EPI program youth.
