Personally, I don't see a problem with having a drink before play. I don't suffer from ADD or ADHD, per se, but as one who is generally tightly wound....it helps me relax. This is coming from someone who doesn't drink on a regular basis. I'm perfectly able to enjoy activities without alcohol, but I see nothing wrong with drinking in moderation. As far as smoking anything besides cigarettes, it renders me completely useless and flaccid, and it really has never been my "thing."
