Yes. It would also clear-out the National Parks of Naughty Vegetable growers who usually pack heat and leave a mess.
But the big bucks are in coca processing - why cant we grow that here? Is there something geographical about coca? I am sure Boulder CO or Aspen has the same geo weather as does Peru?
Allow individuals to grow their own naughty vegetables and the cartels are toast.
Not going to happen.
Lots of lawyers, drug counselors, prison guards etc derive their income off the illegal trade.
But I would think it better to let the folks grow their own and keep the money here.
They are going to do it regardless of where it comes from.
