What do I do?

i have i am 17 in 11 now and my friends still do that stuff, my bestfriend is really gotten her self in troble with it, i told her i am still her friend but also told her when she around me that keep that stuff away cuz i have more respect for my self then to do stuff that would harm me. and another one like to get drunk alot, they both know where i stand on it i tell them i dont like it dont do it around me and they respect my wishes because they are my friends. but thats the kinda relationship i have with my friends.

I can't really say much because I do smoke fags and weed, and do other things that you have mentioned. But that doesn't make me a bad person, it doesn't affect my friends and how I treat them. Its just one of those things lots of teens and older people go through, to learn, deal and enjoy things in life.

However it is very wrong how you school is dealing with it and if it upsets you so much then talk to someone about it, your headteacher, and your friends if what there doing is bothering you as well.
