Marijuana use is harmful and should be discouraged
Marijuana use is associated with dependence, respiratory and mental illness, poor motor
performance, and impaired cognitive and immune system functioning, among other
Marijuana intoxication can cause distorted perceptions, difficulty in thinking and problem
solving, and problems with learning and memory.
Studies have shown an association between chronic marijuana use and increased rates of
anxiety, depression, suicidal thoughts, and schizophrenia.
Other research has shown marijuana smoke to contain carcinogens and to be an irritant to
the lungs. Marijuana smoke, in fact, contains 50‐70 percent more carcinogenic
hydrocarbons than does tobacco smoke.
