Marijuana use and youth

The teenage years mark a time of exploration, growth, and risk-taking. Some risk-taking behaviors help to foster independence and identity development. However, other risk-taking behaviors — such as marijuana use — can have detrimental effects on the health and well-being of our youth.

In the latest Community Assessment, the Milton Coalition reported that the rate of Milton High School students who reported regular use of marijuana was higher than national averages of youth marijuana use. The assessment also highlighted community voices that reflect attitudes and beliefs towards substance use. For example, “The mentality toward marijuana has changed. Legalization of recreational marijuana had decreased the perception of risk among parents and kids.”

Milton’s higher than national average youth marijuana use and this shift in mentality on the perceived risk of marijuana is especially concerning given evidence to the contrary. Marijuana use is associated with a wide range of adverse health effects on the body and brain.

The human brain is not fully developed until age 25 and youth — whose brains are actively developing — are especially susceptible to the adverse effects of marijuana. A wealth of evidence shows that marijuana use directly affects the brain, specifically parts of the brain responsible for memory, learning, attention, decision-making, coordination, emotion, and reaction time.

Marijuana use has also been linked to an increased risk of mental health issues, such as depression and social anxiety. Further, recent studies report that approximately 3 in 10 people who use marijuana have marijuana use disorder. Studies also note that for people who begin using marijuana before age 18, the risk of developing marijuana use disorder is even greater.
