Vaping Marijuana

THC is the main mood-altering ingredient in marijuana (cannabis). The extracts or concentrates used in vaping marijuana are extremely potent – between 50% and 90% THC.

Cannabis use can have long-lasting or permanent effects on the developing adolescent brain. It contributes to decreased problem-solving skills, reduced attention span, and poor memory. This can lead to a decline in school performance.
