Need to know...friend is into hard drugs?

Hey People,

I’m writing to all of you on kind of a sad note. I think a very good friend of mine is on drugs and I’m really worried about him. A couple of months ago I starting noticing some changes in my friend, mostly his lack of punctuality, realiability and endless partying. About a month ago I asked him straight out what the heck was up with him “are you on drugs?” I said seriously to him, but he swore up and down I was crazy so I left it at that.

Well, just now I found a plastic baggy (you know the tiny zip lock druggy baggies) with a bunch of small white pills. He’s been going out partying like crazy and I know he hasn’t been paying his bills because I picked up the phone at his place the other day and I had a creditor on the other end. This is so out of character for him. I’ve lost friends to drugs and alcoholism before and I’m determined not to let it happen to him. I left the baggie full of all the mysterious pills exept for one, and wrote on the outside of the bag “what the **** do you need these for?”

I want to know what kind of drug it is. How can I find out? Right now the only thing I can think of is going to the university and finding a chemist. Anyone have any advice on how I should deal with this situation?
