Marijuana intoxication can cause distorted perceptions, impaired coordination, difficulty thinking and problem solving, and problems with learning and memory. Many research studies have shown that marijuana's adverse effects on learning and memory can last for days or weeks after the acute effects of the drug have worn off. Chronic marijuana use can lead to addiction. Addictive behaviors may result in harmful effects on social functioning in the context of family, school, work, and recreational activities.
