Addiction recovery programs and religion in the US compared to the world

I've been a marijuana addict for 20+ years. It seems that every program tied to sobriety or recovery in the USA is basically a Christian front.

AA meetings are held in churches and the whole program is about submitting to the concept of a "higher power".

I was enrolled in a sobriety program and the same thing applies there- every counselor may as well be a priest, every speaker is a recovered born-again type.

Is this unique to the United States? Do other countries' recovery programs also rely this heavily on religion?

From my observation, I am theorizing that a lot of addiction problems in the United States stem from psychological problems brought about by our culture- which is heavily based in Christian concepts and a top-down hierarchy. For many, addiction is an escape from the problems and distortions of modern society and these programs only serve to help you accept it and assimilate. AA says the program "works if you stick to it" (which is like saying 1/3 of the time it works 100% of the time...). Well of course, it's a Christian program designed to help people be more Christian to navigate a Christian world. It works because it's aligned with existing power structures, not because of any divine power or righteousness. Any thoughts or input?
