Well I'm not in AA so I guess this might not be relevant, but for me: I have a problem with alcohol. I don't have a problem with drugs. Sure, I had a time in my teens and early twenties when I tried everything there was to be tried, but that was a very long time ago and I don't use drugs in any regular way. I don't even take painkillers if I can avoid it. But, and here's the but, if I was at a party and I was offered a joint, I'd take a toke. It happens about once or twice a year, and mostly it reminds me why I don't do it, but occasionally its fun too.
I don't think it jeopardises my sobriety from alcohol because it isn't alcohol.
