I need to say something there would be no black market unless the gov't sells it at horrible prices. Kids wouldn't get into other drugs if it wasn't for dealers, you would never get asked at a cafe "want some herion". But the dealer will ask this. Plus if it is legal for adults it most likely becomes harder for childern to get such as beer. I can easily get illict drugs but alcohol is hard. Plus the government could spent more time stopping youngins and let the responsible adult use it as they want.
