i think it has to do with ones emotional being...those who arent entirely happy with life i think are more prone to doing drugs...im not talking about the kids who think its cool so they smoke weed with their friends on the weekends...im talking about the ppl who sense an emptiness inside of them...got some issues...are down in the dumps, etc etc...you aint happy with life, with yourself, with whatever, for a few hrs on substances they can feel good...i for one belive ppl should mind their own bussiness when it comes to ppl doing drugs...so heroin and meth are hard to kick, im sure the ppl who took them the first time were aware of the problems associated with that garbage, one look down skid row and you can figure out for yourself that hard drugs arent good for you.
