You don't know the first fucking thing about AA, so just stop talking about it right now while your leg is only knee-deep in your mouth. AA does not use religion or God at all; it simply uses the concept of a Higher Power, ANY Higher Power. Half the people in AA are agnostics and atheists, and they do just fine.
If you believe he really passed those tests you're even stupider than you present yourself to be.
Even if he did pass them, all that shit with him a while back was clearly the behavior of someone who is suffering from prolonged drug use. He's manic-depressive and he was in a huge manic state at the time, which was probably exacerbated by him not having done drugs, if that was the case. I love how he laughed at people who OD, yet failed to mention that he OD'd in 1998 and his own father turned him into his probation officer as a result.
Also, about people who simply stop using drugs: those people aren't "addicts", they're heavy drug users. There is a difference. For those whose lives are in jeopardy due to their drug use, they cannot simply stop, or else they would before their lives deteriorate drastically, rather than afterward. As someone who used to drink so heavily that I would puke into a cup in the morning and then drink my puke because of the alcohol in it, and as someone who put a loaded shotgun in my mouth before I quit drinking/drug use, I don't have any tolerance for some dipshit who clearly doesn't know the first thing about AA or addiction in general.
