Broadly speaking, I think I'm in favor of legalizing and regulating recreational drugs, but hearing stories about the violence in Mexico, I don't know if an American can partake in good conscience without knowing exactly where what they buy comes from. I think a lot of Americans can now get marijuana from reputable, local sources, although that's still moving slowly in some places (it's still illegal under federal law, even if it's legal under state law, which I think makes it difficult for those businesses to get loans and insurance and whatnot; some municipalities and individual landlords may also be reluctant to allow those businesses until federal law is cleared up). I've never been into a store, but I imagine if you ask where their stock comes from, they could tell you. Anyway, I heard yesterday that during this latest campaign season in Mexico, 30 candidates for different offices were assassinated. The mayor of Cotija de la Paz, Michoacan (in the southwest, on the Pacific coast), was shot 19 times the other day. I don't know if the US is the sole market for the Mexican cartels, but surely it's the largest. I believe they also get most of their guns from the US too, but I guess I don't know that for sure.
