I personally don't do drugs or ever tried to, or ever think about doing them. But I have a really close friend of mine who does. She used to do a lot of different drugs, that were somewhat not very serious (shrooms, xanax... not important ). She has been smoking weed for about 2 years now. Yesterday she told me she would like to try pcp, acid and ecstasy. I am very afraid she would try any of them, especially pcp. I heard a lot of scary stories, and I wonder why would she want to even try them, I am pretty sure she heard them too. She says she is curious... I am not really sure what to do, because those drugs are addicting, they are not like marijuana or some other ones she tried, it is more hard ones, and her life would be completely ed up in my opinion. I don't want her to, I know she can have a great future, I would hate to see her fail in life. And especially knowing that I was there when she was about to try, I knew she was about to and I didn't do anything to stop her. This thought kills me. I want to stop her before she does something stupid like this. I don't want her to try it. What should I do though? How can I stop her? She already sells things out to get enough money. This scares me.

You can't really stop her, because she is going to do it anyway. Perhaps you can get her to an NA meeting, let them carry the message to her.
