I have never smoked weed and I would not go as far as say it is harmless, but it is not a dangerous drug like the others. I see way more harm done with alcohol and you cannot compare the two when it comes to that. I agree when it was banned it was available if you knew where to look so being legal actually protects those using it far more. The politicians voting on such decisions are not actually part of every day life so are totally out of touch with reality.
