Experts Warn: Who Should Avoid Cannabis Use
An umbrella review of meta-analyses of randomized controlled trials and observational studies has assessed the risks and benefits of cannabis use. The review found that cannabis-based medicines increased adverse events related to the central nervous system, psychological effects, and vision in people with mixed conditions. Cannabidiol was found to be effective in reducing seizures but increased pneumonia and gastrointestinal adverse events. Cannabis-based medicines or cannabinoids were found to reduce chronic pain but increased psychological distress. The review also highlighted the harmful effects of cannabis use during adolescence and early adulthood, in people with mental health disorders, during pregnancy, and while driving. Overall, the review supports the avoidance of cannabis in certain populations and highlights the need for caution in its use.
