I don't think this dude knows what he's talking about........... If you knew anything about anything you would know why they are growing the shit here rather than in Mexico.
O.K i will clue you in......ITS WAY EASIER AND MORE PROFITABLE. What they do is they find someone who can grow herb back in Mexico and smuggle THEM into the U.S . to grow massive grow ops in our forest such as Sequoia National. Most of the time these guys are forced to do the shit too. They kidnap there family and tell them if they don't follow through they will kill there family.
