New Study Links Teen Cannabis Use to Significant Mental Health Risks

A landmark study tracking over 463,000 adolescents from ages 13 to 26 reveals that teens who used cannabis in the prior year face significantly elevated risks of developing psychotic disorders, bipolar disorder, depression, and anxiety in adulthood. The research found that the risk of psychotic and bipolar disorders roughly doubled among cannabis users during their teenage years. These findings underscore the vulnerability of the adolescent brain to cannabis exposure during critical developmental periods. The study highlights important implications for parents, healthcare providers, and policymakers in Puerto Rico regarding youth substance use prevention and mental health screening.
