Coming from a different poster, I'd rate it as concern trolling. There's a lot of it swirling around legalization, more of the usual fear mongering. I don't think that was the intent.
Despite prohibition, cannabis has become a normal part of life in America. Nothing short of a police state can change that so we should stop pretending that it might, stop pretending that locking people up for a mostly innocuous pastime somehow serves the common good.
Yeh, sure, I get it that the war on marijuana is really just a jobs program, workfare for brownshirts, politicians, lawyers, judges & etc, but we ought to be able to create jobs w/o creating victims at the same time.
