Health Effects

Marijuana can have short-term and long term effects on a teenager’s health and developing brain.

Short-term effects: problems with memory and learning, distorted perception (sights, sounds, time, touch), trouble with thinking and problem solving, loss of motor coordination, increased heart rate, anxiety

Long-term effects: Marijuana smoke contains some of the same cancer-causing compounds as tobacco, sometimes in higher concentrations. Studies show that someone who smokes five joints per week may be taking in as many cancer-causing chemicals as someone who smokes a full pack of cigarettes every day. Additional health effects of Marijuana include increased risk of chronic cough, bronchitis, and increases risk of schizophrenia in vulnerable individuals.
