Since the 1930’s, some choose (instead of or after treatment or rehab options) the twelve step model of recovery. The 12 steps work in lives of addicts and alcoholics. At times, rehab is critical to those in the lowest levels of active addiction because detoxing can be dangerous. There are also alternatives that provide a different view, many get clean, get sober without rehab. Many are introduced to the 12 step recovery in rehab and some attend after after treatment or rehab.
