Vancouver Mayor Larry Campbell wants to legalize marijuana sales. "Taxes levied on marijuana sales could add to the resources for treatment," he said at a meeting of the British Columbia Civil Liberties Association. "Remember, the B.C. marijuana trade is estimated at $6 billion [US$4.4 billion] annually–larger than construction or forestry."
Of course, that's the value of the crop at black market prices. Imagine how much forestry would be worth if trees were illegal.
