The 12 Steps are the Green way to recovery.
Yes, I am kidding.
Sure, the recovery rate in AA is low... because the meetings are open and most people take years to get to a point of willingness. AA is meant for the 'hopeless alcoholic,' not the newbie abuser with plenty of spunk and lots of ambition. Read the histories written by Dick B. and you will see that AA has changed dramatically in that respect.
The 'pill' does not rebuild the relationships broken by addiction, nor does it cure the inner suffering the Steps address.
No pill can replace the healing of repentance and conversion. No pill can make your amends for you. No pill can replace the sense of God's love and mercy.
No pill can make you Sober.
