I get the point these are trying to make, and I'm sure probably a few of them are made up (not saying that they aren't all possible but usually a % of things like this are), but I would not be cool with my kids teacher getting stoned before school if I had any. That really goes for most jobs. To me it's on par with drinking or doing any other drugs before or while at work. If they want to smoke after the school day to unwind, I'm fine with that. If they want to smoke the whole weekend and during breaks 24/7, I'm fine with that too. But if someone is in a spot to educate people, or you are a nurse, or doctor, or firefighter.. like some of those are saying (even though only the teacher one implied before/during) you should not be doing anything that impairs your judgment at that time. Just my opinion, thought I'd say something. I'm gonna smoke some reefers later tonight.
