I had the same reaction. It scares me to think that intelligent people are just now realizing the consequences of making a highly-demanded product illegal. Really, all drugs should be legalized and controlled. The problem is that we're not only facing religious drones who can't see past the end of their noses, but more importantly, we're up against big money. And big money has power. I'm talking not only the cartels but private prison owners. Do you think those guys want to see their customer(prisoner) numbers decrease? Or what about law enforcement and the drug agency? You think those guys want their funding cut? Because if you remove drug-crime control you remove the majority of their work.
The convenient thing is that this drug-scare hysteria that has this nation by the balls is what keeps this endless cycle going. Those who benefit where the "righteous" mask of public protector or advocates for our children.
