In any case, the motivation for my comment was to point out that many of these "xA" programs are inspired by the 12-step "AA" program. That program is not scientific, or even amenable to change as new evidence about the efficacy of sobriety comes in.
Rather, it's dogma. Whatever white-washing of AA's mention of "God" over the years as "higher power" doesn't change the fact that it's not science-based.
Does that mean it's completely useless? No, but as others have pointed out studies of its effectiveness are rather damning[1]. It just bears pointing out when treatments for addiction are discussed that AA is a dogma-based therapy, because many people suffering from addiction think AA is just what you're supposed to do.

It works for some, but anyone who says its not a christian organization is absolutely lying - its like taking the caramel coloring out of cola - its still cola, it still tastes like cola, you just took away the color that reminds people that its cola.
I go to Agnostic meetings that don't involve any prayer or spiritual aspect, just a group of drunks gathered together helping each other to stay sober. So if the whole religious or spiritual aspect of the program leaves a bad taste in your mouth, try finding a secular meeting in your area: https://secularaa.org/tsml_meeting/
