Cannabis isn't "Black market"
Dealing in Cannabis is no longer a real "Black Market" activity; it is now more like a Gray Market activity in those places where the backward legislation continues to regulate it in some way.
And make no mistake-- all legislation is backward.
Cannabis is legal, except that some locations still legislate against it, other places demand their piece of the action, and other places insist you only buy certain types of it from certain sellers. None of which is legitimate in the slightest. Just like gun "laws".
And it was never wrong to begin with.
