I hear wat ur saying Higi, i'm tryin do the same thing, stop smokin dope before my exams..but its virtually impposible to turn ur back against perr pressure no matter wat anyone says. Your mates smoke a joint u gotta toke from them. Best thing is make sure u dont buy any dope urself that way it stops u from knowing that u can smoke wen ever you want. Tell ur mates tht u wana stop 4 a bit, i did and they actually helped me out, we did stuff that we wudnt normlly do which was cool. Will power is a powerful thing if u have it.

Peace out
