Shadow asked whether Al-Anon cautions against alcoholism and becoming an alcoholic as part of its program of recovery. My answer would be that the focus in Al-Anon is on recovering from the effects of someone else's alcoholism whether it is in a friend or family member. The focus is on sharing our experiences of dealing with alcoholism in our lives, how we got better and what steps we are taking to achieve serenity.
There are many recovering alcoholics who come into Al-Anon and find their serenity in its program. Likewise I am sure that there are Al-Anons who make it to the rooms of AA. But both programs practice the 12 steps and Al-Anon's twelve steps are based on those from AA. It is hard for me to imagine that anyone who has worked the steps in Al-Anon and achieved some manner of recovery would want to jump into the fire by becoming an alcoholic. But strange things happen and "never" is a God word.
