Unless we ran it like the alcohol system, with dry counties and wet counties. If the states were given the choice to license and regulate there would still be areas more "liberal" than others. IE: places to visit, ie: tourist dollars. Perhaps not from all over the world but the US has a hell of an internal population. I can't imagine Alabama or Misissippi giving out licenses so those people have to go somewhere. Oregon perhaps, lots of nice forests, or California, cities and amusement parks, or Colorado.. anyway you see my point. We have enough population to support internal tourism. The real point is how the Dutch experiment has worked. Not only does the Dutch Model support Health Care and other social programs it also reduces "hard " drug use significantly.
So despite all the advantages; less pollution, saving the family farms, creating thousands of jobs, breaking free from imported oil, securing the borders, controling the "scourage" of drug abuse; the "representatives" of the people have not found the will to reevaluate the 1936 Marihuana Tax Stamp Act and consiter the MANY uses of this most valuable plant.
Please pass this around your personal "circle" of friends....
