Marijuana Use and Mental Health Problems
Below are three recent studies examining the role of cannabis use and negative mental health effects among young people.
The first study examined the influence of adolescent marijuana use on adult intelligence.
The study was published in the journal Drug and Alcohol Dependence.
The key finding was that “ever use” of marijuana during adolescence was associated with small but significant declines in intelligence in adulthood.

A second study examined the cannabis consumption and the risk of psychosis.
The study was published in the journal Evidence-based Psychiatric Care.
The authors of the study concluded that smoking marijuana early in adolescence (before age 15) and frequent marijuana use increased the risk of developing psychosis.

A third study examined whether marijuana use results in amotivational syndrome among college students.
This study was published in Prevention Science.
The study findings indicated that marijuana use significantly and longitudinally lowered initiative and persistence, and that cannabis use is a risk factor for decreased general self-efficacy.

Combined, these studies paint a picture of marijuana as increasing mental health risks for users, including reduced intelligence and increased likelihood of psychosis and amotivational syndrome.
These risks appear especially among youth and young adults, highlighting the critical need for more marijuana education, prevention and regulations to protect young people from accessing, initiating and eventually developing regular marijuana use patterns.
