AA recognizes atheist groups, because we have one in Kalamazoo every Saturday. (See Events) But some atheists in the media think we ought to stay away from such groups because they are offensive to nontheists, when they "urge" us to accept a higher power and to turn to god, and to pray and meditate. It doesn't have to be that way. Being in a room full of atheists recovering from addictions is refreshing and uplifting. It's also helpful because we don't have to listen to theists explaining how their god lifted them from the gutter.
In the official AA publication called Box 459, they published a story recently about a man whose higher power is a GI Joe doll. That doesn't sound like a group hell-bent on forcing everyone to join a religious cult.
Even if you can't get to an atheist recovery meeting, do what I do: go to a regular meeting and talk about how you, as an atheist in recovery, can still make the Steps work to your advantage. You don't have to "believe" in god: The only requirement for membership is a desire to stop using.
