Genetic Basis of the Risk and Consequences of Cannabis Exposure in Humans

Recruiting now · Phase 1 · Has a placebo group

Conditions studied: Schizophrenia, Cannabis Use Disorder

In brief

Cannabis is widely used worldwide and is associated with negative outcomes including cannabis use disorder (CanUD), psychosis, and cognitive impairment amongst others. Given the legalization of "recreational" and "medical" cannabis globally, the increasing availability of cannabis, the higher potency of cannabis, the availability of highly potent cannabinoid products, the commercialization of cannabis, and the rising rates of cannabis use, it is critical to understand how genetic factors influence 1) an individual's vulnerability for addiction and psychosis, 2) the response to cannabinoids, 3) the response to novel treatments for CanUD. CanUD is strongly genetically influenced; the investigators published the first CanUD genomewide association study (GWAS) with genomewide-significant results; however, the precise nature of the contribution of genetic factors in the development of CanUD is still not clear. Cannabis exposure has also been linked to a number of psychosis outcomes including schizophrenia (SCZ). SCZ is highly heritable and population-based and genetics studies both support a bidirectional genetic relationship between SCZ and CanUD. However, the precise contribution of genetic factors in the development of psychosis outcomes related to cannabis are not clear.
