Yeah, teaching is fairly well known for not drug testing at any level, although there are probably exceptions. Stands out compared to most industries/professions that never test since its pretty respectable and provides a nice enough living. I dont know why - Im guessing it comes down to cost, which would make sense. But a lot of sectors engage in it almost because everyone else does it. Corporate peer pressure. Or because of insurance which gives them monetary breaks for doing it on everybody.
I am I - you are you. These are irrefutable truths. Possibly.
