That's a good point. Yeah, a lot of the negativity that I've experienced in altered states have been related to drunks around me or the mixing of alcohol. I must admit, though, a little alcohol doesn't hurt. I remember, once though, several friends and I had bought a six-pack to take with us before we turned on. After the LSD started to take affect, we just left the six-pack beside a tree and never touched it until we started coming down (I think thirst had kicked in).
