Education shouldn't be about not doing drugs, but about not getting addicted to them. It's perfectly fine to occasionally take drugs (you know, like CH₃CH₂OH or C₈H₁₀N₄O₂, the former of which is a lot worse than a good number of illegal and "dangerous" drugs like THC), it's not fine to be constantly stoned/high/drunk/intoxicated. I don't want even more "drugs are bad, mkay kids" in schools. Drugs are perfectly fine and have been part of human civilization for thousands of years now. It's only been very recently that people got the idiotic idea to crack down on them.
