One of the most widely used approaches is the 12-step approach, which was pioneered by Alcoholic’s Anonymous in the 1930’s.   This is a primarily holistic approach to recovery and many claim it to be the only realistic way of achieving sobriety. There are other approaches that deal less with spiritual matters and focus more on events from your childhood that could have precipitated the addiction. There are many different theories available on addiction and many different drug rehab facilities to choose from. The bottom line is that if you are serious about getting better, then you improve your own chances tenfold.
