Nope, never have, never will.
I find it disconcerting that people need a controlled substance to feel pleasure or just good. I've got endorphins for that. Oh, endorphins as well as adrenaline give you a great rush btw, equal to morphine. Runners high? That's a motherload of endorphins gettin' loose.
Also, there was a study done that said that a good night at a casino (meaning, winning!) results in the same thing as being drunk- lol. The same brain centers were very active for both.
