Patient discussion about heroin

Q. What are the effects of heroin addiction? I just found out that one of my block mates has been using heroin to keep her up all night just so she can study for our exams. But I don't think it's doing her any good. I asked her if she wanted to talk about it, but she refused. I would like to help her get out of heroin addiction while she still can.

A. oh one my favorite ones for sure. the up side is nice sleepy time, complete numbing of unwanted emotion & sense of well being. the bad side it's unhealthy. i don't know how much it's the dope or the cut but that shit is hell on the g.i. tract, liver & kidneys. prolonged use over numerous years of time really change the brains factory specs. in other words physical withdrawl hell say two, three, four weeks or so (varies among bodys) but the psychological aspect can be a long suffered challenge to deal with. let's just say in my opinion one would really have to come to an internal & external relationship with life that they decide that their time to go straight & stay straight has arrived. & i mean after the detoxification process mentioned, that the same conviction, the same resolve remains.
