I'm an NQT in a challenging London school and have had a few of kids turned up totally off their faces on drugs. Any advice on how to deal with it? The issue is that I can't 'prove' it and I have to be very careful with the way I deal with things because some of these kids are very volatile. Any suggestions?! I guess I should add that they are not being particularly disruptive, it's just rather unnerving more than anything.
