I've attended both fellowships and I choose NA as my home. AA states in their literature "remember we deal with alcohol: cunning, baffling, powerful." by not adhering to that, the person is disrespecting what the fellowship stands for. its like walking into a Judaic temple and saying "hitler wasn't really so bad, we got Volkswagen and the Autobahn from him, lots of advances in modern medicine, etc". NA is a lot more free when it comes to discussions as NA is about addiction which can be superimposed over various lifestyle addictions and struggles as well. we in NA do not address the drugs as the problem, but merely they were a symptom of something deeper that we need to look into. I do go to a private AA meeting once a week which consists of my sponsor, his sponsor, my sponsor's wife, and the various sponsees whom we all go to both fellowships so more or less its just a "12 step" group centered on getting better. I recommend checking out NA, each fellowships fits better with certain people. I've been to heroin anonymous, cocaine anonymous, marijuana anonymous, al-anon, alcoholics anonymous, narcotics anonymous, emotions anonymous, and families anonymous. NA is my chosen home.
