Regular Marijuana Users May Have Impaired Brain Reward Centers

Brain 2New research shows that regular marijuana users show impairments in the brain's ability to respond to dopamine – a brain chemical that is involved in reward, among other functions.

Although this research can't determine if regular marijuana use causes deficits in brain reward centers – or if users take marijuana to compensate for less reactive dopamine systems – these results could help explain why regular marijuana users are more prone towards depression, anxiety, irritability, and increased sensitivity to stress.

The study, first-authored by NIDA Director Dr. Nora Volkow, was supported by the intramural research program of the National Institute on Alcohol Abuse and Alcoholism.
