No. I'm not interested. I value it that my mind works the way it should. I would hate to lose control. Some of the things you named aren't good examples of legal drugs. Chocolate has medicinal properties. It may be "misused" but when it is, it's because the person eating it has a need for its medicinal properties. You can call it a "chocolate deficiency" if you want. Personally, I rarely eat it. Alcoholic beverages have legitimate uses, and as long as it's not abused, it shouldn't be classified as a drug. You could probably classify most food and drink as a drug if you look at it that way. Caffeine also has medicinal properties, but I personally stay away from it almost totally. I have never smoked, and I go out of my way to avoid breathing secondhand smoke. Tobacco is a good insecticide. That's all it's good for. Making something dangerous legal won't tempt me to try it. I know better than to assume making something legal makes it desirable. Abortion is legal, too, but it's still just as deadly. But the fact it's legal deceives a lot of people.
I'd only do pot because it has more medical uses than most of the other drugs (including tabbaco and alcohol), and you can't really do much harm to others cause most people are too stoned to want to move from their seat.
