Methamphetamine, a highly addictive stimulant drug, whose abuse has reached epidemic proportions in many parts of the United States, causes long-term changes in the human brain that are associated with impaired memory and motor coordination, according to a study published in the March 2001 issue of the American Journal of Psychiatry. Researchers found that these effects are seen even in methamphetamine addicts who have been off the drug for 10 months or more.
