Adverse effects of marijuana use.
Marijuana has consistently been reported as the most commonly used illicit substance in the United States each year. Currently, the legalization of marijuana is up for debate across the nation. While marijuana use is prevalent among the adolescent population, research has shown that there can be devastating effects on health and well-being. A review of the literature shows that marijuana use can have a negative impact on physical health, psychological well-being, and multiple psychosocial outcomes. Adolescents who used marijuana more frequently and began using marijuana at an earlier age experienced worse outcomes and long-lasting effects.
