The Obama Administration, together with Federal partners and State and local officials, is working to reduce the use of marijuana and other illicit drugs through development of strategies that more fully integrate the principles of prevention, treatment, and recovery.

THC acts upon specific sites in the brain called cannabinoid receptors, triggering a series of cellular reactions that ultimately lead to the "high" users experience when they smoke the drug. Marijuana intoxication can cause distorted perceptions, impaired coordination, 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. In fact, marijuana smoke contains 50‐70 percent more carcinogenic hydrocarbons than does tobacco smoke.
