As an implicit atheist I get where your coming from. AA/NA dose come off as religious but its not a religion. It is however faith-based so IMO it is in the category of quasi-religious or new age or whatever. Massive amounts of people do get clean/sober in AA/NA and outside of AA/NA.
I go to open meetings of AA as AA dose not demand I believe or do anything if I need no to do such. I also use recovery tools like;
Women for Sobriety, SOS, LifeRing, SMART, CBT, Urge Surfing, DBT and
AVRT along with SR and other things to keep me track with my wellness journey.
So there's that, what do you think?
