Wow. I'm really sorry to see what had been an interesting discussion blow up.
Addiction, for anyone who has had their lives touched by it, is horrendous. It takes good, loving, smart, caring people and destroys them. People should be on the same side, the side of healing, not picking apart one program (among many) that has worked for so many people.
AA does not have to prove anything. If people like it, they should go. If they don't, they shouldn't. There are options. CBT in various forms has been around a long time. I would bet most treatment centers and institutions use some version of CBT. Therapists and docs should certainly be aware of options. AA is not the only one. It is one.
But being informed is critical, as in, AA is not only about "Abrahamic religions"; for example, many Native Americans who do not follow anything close to an "Abrahamic religion" are very comfortable with AA. That is not to say anyone else should be, but AA is certainly not all about Abrahamic type religions.
Again, one hopes we are all on the same side; supporting people heal from addiction on whatever path works for them.
