You can also go to most NA meetings if you’re open to it. They are generally pretty open and accepting and in my experience can offer a more diverse crowd than AA meetings.

Another one I highly recommend is Refuge Recovery. There are not a ton of meetings but if you can find one I prefer them. YMMV. 12 Step claims to be non-denominational, and I guess technically it is, but you will run into a lot of god with a capital G talk that can rub some people the wrong way. Refuge Recovery is very similar to 12 Step groups but it is based on the Four Noble Truths and Eightfold Path from Buddhist philosophy. If that sounds like it might be up your alley, their book is excellent.
