Hey, I think I've seen you around the forum.
I feel similarly about psychoactive drugs. I do consume small amounts of caffeine (via chocolate and the occasional caffeinated tea), but I try to avoid it since even those amounts can make me jittery and thus I don't drink coffee at all. I don't feel any desire to take recreational drugs, legal or otherwise. I suspect this qualifies as an unusual tendency, so it's always interesting to meet people who feel similarly. Nevertheless, I have a tendency not to mention this fact spontaneously for fear that people will feel I'm judging them.
