Treatment is one component of a strategy to reduce substance abuse. It can include detoxification; inpatient counseling; outpatient counseling; therapeutic communities; and self help groups. Referrals can take place in settings such as emergency rooms; employee assistance programs; churches; and physicians' offices. Unmet treatment needs can cause other social problems such as crime, gang violence, and decreased productivity in the workplace. People seek treatment because of a variety of drugs, but alcohol leads all other substances as the cause of drug admissions. This paper provides a description of the 13 principles of effective treatment for substance abuse. Information is also provided on national organizations, publications, and names of community leaders with expertise in the treatment area to assist health workers in understanding the treatment needs in their community.
