A 12-Step Program is a set of guiding principles outlining a course of action for recovery from addiction, compulsion, or other behavioral problems. The program is based on the idea that individuals can help each other achieve and maintain sobriety by practicing a set of spiritual principles. The 12-Step Program was originally developed by Alcoholics Anonymous (AA) and has since been adapted for use in other recovery programs. The term 'Rehab' is a shortened form of the word 'REHABILITATION', which is the process of helping an individual recover from an addiction or other behavioral problem.
