Treatments for drug abuse can begin only when the substance abuser accepts that the problem exists and agrees to stop using it. He or she must understand that drug abuse is curable and must be motivated to change. The goal of treatment for drug abuse is abstinence. Among drug abusers, the combination of good health, social support, and motivation can greatly increase the likelihood of sobriety.
