I've sometimes thought that the best way to demystify drugs for young people would be to have a age limit above which things get legal. Like 65. Then getting stoned might start like being seen as akin to Dad Dancing, Young people would be likely to scorn it. (Though with Bill Bailey winning Strictly Come Dancing, Dad Dancing might get a bit more respect now.)

But I can't see any of that as relevant to the matter of finding ways of getting out of the hole our societies seem to be in.
