I have heard rumors of commercials selling on the black market not confirmed but I am sure it happens especially if they have a hard time paying bills.

Like you said it's cheap enough in the stores, no reason for people to buy from the black market, that intent of the law worked.

I just don't see the benefit of not allowing people to grow a few plants for fun, like tomatoes. People are going to do it anyways. It's going to be interesting to see how they handle things after July, if they demonize people for having a couple plants in their garden.
