Abstract
Objective: Cannabis use is increasingly normalized; psychosis is a major adverse health outcome. We reviewed evidence on cannabis use-related risk factors for psychosis outcomes at different stages toward recommendations for risk reduction by individuals involved in cannabis use. Methods: We searched primary databases for pertinent literature/data 2016 onward, principally relying on reviews and high-quality studies which were narratively summarized and quality-graded; recommendations were developed by international expert consensus. Results: Genetic risks, and mental health/substance use problem histories elevate the risks for cannabis-related psychosis. Early age-of-use-onset, frequency-of-use, product composition (i.e., THC potency), use mode and other substance co-use all influence psychosis risks; the protective effects of CBD are uncertain. Continuous cannabis use may adversely affect psychosis-related treatment and medication effects. Risk factor combinations further amplify the odds of adverse psychosis outcomes. Conclusions: Reductions in the identified cannabis-related risks factors-short of abstinence-may decrease risks of related adverse psychosis outcomes, and thereby protect cannabis users' health.
期刊介绍:
Journal of Dual Diagnosis is a quarterly, international publication that focuses on the full spectrum of complexities regarding dual diagnosis. The co-occurrence of mental health and substance use disorders, or “dual diagnosis,” is one of the quintessential issues in behavioral health. Why do such high rates of co-occurrence exist? What does it tell us about risk profiles? How do these linked disorders affect people, their families, and the communities in which they live? What are the natural paths to recovery? What specific treatments are most helpful and how can new ones be developed? How can we enhance the implementation of evidence-based practices at clinical, administrative, and policy levels? How can we help clients to learn active recovery skills and adopt needed supports, clinicians to master new interventions, programs to implement effective services, and communities to foster healthy adjustment? The Journal addresses each of these perplexing challenges.
