You should be able to pass those crappy home drug tests with a little bit of bleach in your urine before it's tested. Or you can get one of your friends to keep you with clean piss.

Tell me this, are your grades good? If they are, you should be able to talk to them about it. Don't just wait for them to hand you your sentance, take a stand! Print off some of the research stuff off this great site, show it to them, tell them that you are smart with it and you never smoke and drive, show them that you aren't letting MJ fuck you up. Not a few other members of this site have done that, with much success.

Hope it works, I'll smoke a bowl for ya'!
