I'm frankly astonished that we made it ELEVEN PAGES without this turning in to a flame war. The mods probably are too...
OT: Why don't I do drugs?
Because I've done it all already. I don't feel the need to do drugs any more because I have had the experience that they offer. And, in my mind, once you have had that experience there's not a lot of reason to go back to them.
If something came along I hadn't tried which offered an experience unlike one I'd already had I would probably try it.
In terms of the more "party" drugs, things like e, I've done them too much and have just stopped enjoying it. A developed physical resistance to their effects makes taking them more costly than it is worth, especially considering where I live they are already hugely expensive.
Finally I find it a lot easier, these days, to say no to everything as I don't feel I have it in me to say yes to one and no to another.
Having been a part of the greater spectrum of drug use do I think it is a good thing? No.
Do I think, if you are interested in doing it, it will be a worthwhile experience? Yes. If done with moderation and if you pick the right substances. (IE: LSD can give you eye opening and inspiring experiences, Meth shouldn't be done by anyone, ever!)
I'd also put it out there that Alchohol is close to the single scariest drug I have ever experienced or watched people become addicted to.
And, again, good on everyone for discussing this (mostly) maturely.
Completely off topic, if you are curios to try drugs, find someone who is mature and responsible with their drug use and willing to share with you in an unbiased fashion.
Make sure you plan what you are getting yourself in to, don't take a drug that will last for 8 hours if you have work in 6.
And, Research, Research, Research. Know what to expect, know what the dosage is and how long it will last, know when it will peak, settle and drop off.
