I do agree with Martin that mind altering drugs do not enhance the human experience. As to whether pot should be legalised, I also agree with Martin - it shouldn't. But for totally different reasons, namely that the economies of so many developing countries like Afghanistan, Turkey etc etc would suffer as the price of the stuff drops with legalisation.

Tobacco, now there's a drug much more destructive - why isn't it banned, I wonder. Ah, yes, its tax revenues support the NHS in the UK and help keep taxes down in other countries.

Nobody is immune from double standards. When it suits them.
