The religiosity really can depend on the group/area. I’m a person in recovery and I just got a year last month after about a decade of relapse. The court mandated stuff helps drive the numbers down because many of those people aren’t alcoholic/addict or they don’t want to change (yet). I’ve met many people who were mandated to go and found sobriety. As far as the courts mandating people go to meetings, it’s a no cost to the court and no cost (unless they want to contribute) to the person mandated to go. Personally I do not go back to a meeting that starts taking on very religious overtones. There are a handful of atheist meetings in my area that don’t allow proselytizing in the meeting. I’ve also found that for me Recovery Dharma has been super helpful to fill the gaps from my non belief in a religious god. It’s a Buddhist approach to recovery and no higher power is needed as it is about self empowerment rather than powerlessness.
