okay hello, i might as well enter thing Post with my comments

Okay i been smoking since i was 9yo (Now 17), and from my view from this is that he needs to crack down on some of his work. talk to him and set some rules, something like if you get meast up grades, no going out with friends for a week to get High.

i mean hell even i know for the past years that have went back that your work needs to come first before any type of partying.

Friendowl is right that there's many reasons why people start, i know my was with stress (With being poor and parents breaking up etc etc), and if it's just because his friends do it that's just wrong. i don't think anyone should be doing anything simply because there friends or someone they know is doing it as well.

but back to what i was saying just set some standers for him, he doesn't seem to care what punishment he gets so the best thing you can do is just be there for him when he is in trouble and not be a ass about the little things.
