Marijuana and Health

Marijuana, like all drugs, has potential risks. Regular smoking of marijuana is associated with breathing problems such as cough and increased risk of lung infections. It can also be addicting and can cause problems with thinking, memory and coordination, anxiety, depression, and other behavioral effects that interfere with work, school, and relationships.
It causes an increase in heart rate, which may increase the chance of heart attack in people who are already at risk. Marijuana can cause problems with brain development in adolescents through 25 years of age that can be long-lasting, including possible decline in IQ among adolescent marijuana users.
