Somewhat enjoyed it when I was younger, mostly because the people I hung out with did it. One of those things where it was a social event. Don't really care for it any more- probably because the last time I tried it I figured I had to take deep drags over and over... big mistake.
I have no problem with people who use it casually or in moderation, but like anything else from food to alcohol, it has the potential of being abused. It's not the pot's fault, just poor judgement on the part of some people.
