I've only ever smoked weed before but i want to experience crack, meth & pills. the only thing that stops me is that i might think i've found that "thing" that makes me happy & i will get heavily addicted. i currently don't touch drugs but really want to start smoked weed again . it's weird considering im a health freak.

I guess your prett young? Try to stay away from the drug scene for as long as you can. Its awsome but like you said, once you get involved its hard to get away.
My little brother (your age) is recently addicted to heroin and it's destroying his life. As soon as people start using drugs like that, all they want to do is stop.
