Personally for me I have heard that people in AA don't like talk about drug use but in 32 years I have never seen anything said in a meeting to anyone when they mentioned drugs. I know they mention it early to start the meeting.
Truthfully I don't hear a lot of people talk about alcohol in a meeting either unless they are brand new or are the speaker.
What I do hear is about how people deal with life sober.
I think anyone with integrity would just let it slide, it's not like it happens every meeting. Talk about anything you want if it helps you stay sober for this 24 hours, just limit it to 3-5 min so everyone who wants to gets a chance to share.
I need less problems not more.
