Adolescent Brain on Cannabis: Navigating the Neurological Risks of Early Marijuana Use

As cannabis legalization expands, understanding its impact on the developing adolescent brain is paramount. This period, characterized by significant neural remodeling, makes teenagers particularly vulnerable to THC's effects. Research suggests that early and frequent cannabis use can impair cognitive functions like memory and attention, and is associated with an increased risk of mental health issues, including anxiety, depression, and psychosis, especially in predisposed individuals. While studies are ongoing and face challenges due to increasing cannabis potency and diverse usage patterns, neuroimaging and longitudinal research are shedding light on potential structural and functional brain changes. Public health strategies must focus on educating youth, parents, and educators about these risks, advocating for evidence-based prevention, and supporting continued rigorous scientific inquiry to protect adolescent neurological development amidst evolving cannabis policies.
