Testing for weed in high school is pointless. It was easier to get weed in highschool then it is now. I used to remember going out for a smoke and being invited to join a session, we'd leave to goto a spot and there would already be a session ongoing. It was awesome. 1 out of 5 people in our smoking area was selling some kind of drug at any given point in the school day. We'd goto class stonned out of our minds and so did everyone else. There were even a few teachers that would come to class high.
Weed does not effect your performance at all. I have a friend, this guy wakes up in the morning and smokes two spliffs. On the way to work he smokes a spliff, on coffee break he smokes a spliff, on break he smokes a spliff, on second break he smokes a spliff, after work he smokes a spliff, on the way home he smokes a spliff, when he gets home he smokes a sliff. His job requires him to think and concentrate all day long. He does a very good job and is currently a supervisor.
If a student is going to smoke weed, they will smoke weed. No amount of drug testing will get around this. There are ways around a drug test and all this will do is boost sales in detox drinks (

Street, in order to overdose on weed, according to what I've heard (I've NEVER heard of anyone ODing) you need to eat twice your body weight in weed. It's things like this that make me happy I live in Canada where soon weed will become leagal, thanks to people like Mark Emery (

It takes more then 15 shots for alcohol poisoning :-P I know from experience.
FYI, I'm going to go smoke weed now, thanks for bringing it up.
