I suspect that if it was totally legal, to grow and possess, there would be no need for these big grow houses. If you wanted to grow some, you could. If you wanted to sell or trade some to a neighbor, you could. Remove the value of it and you remove a lot of the problems from the equation. Just like booze, if people want it, they're going to get it, prohibition or not. Now education about it is a whole nother subject.
