Teen marijuana use is shaped by shifting perceptions of risk, changing availability, and growing links to mental health and longer-term outcomes. In recent years, past-month use trends have moved down for 12th and 8th graders, but risk factors remain. Research connects more frequent use with higher odds of cannabis use disorder, increased depression risk, and possible cognitive effects.
