AA is the gateway for most newcomers in recovery. Many (NA not included) 12-step programs use the exact same literature and steps. As for AA members not caring about pot because it's not drinking, that's bs. It's just that trying to stop someone from getting high while they claim to be "sober" is a waste of time. Most people with any time in the 12 step programs pretty much help those that are new or really trying and have a "live and let live" attitude towards those that are bullshitting themselves about their recovery.
Sober or not, TMFR is probably too stupid to raise a child without fatally harming it within the first few years.
