I used to do drugs in my teen years and in my early to mid-20s. It's worth trying a few things once (pot, cocaine, pain pills, amphetamine, mushrooms, acid) but I would highly not recommend getting addicted or doing it on a regular basis. I've known people who have absolutely ruined their lives, had a friend end up in prison and a couple friends who have had their lives ended because of bad drug habits and doing stupid shit like driving intoxicated. If you are still doing drugs after the age of 30 you are really asking for bad karma.
