I don’t understand your comment. I have found SMART recovery to be free, running off of donations and volunteers. They also sell a few books at a reasonable cost. The only money I have ever spent is donating a few dollars after attending some Family & Friends meetings, and I bought the workbook for something like less than $20.

Another secular alternative is SMART recovery. They have group meetings in-person and online as well as a Family & Friends program. https://www.smartrecovery.org/
