I'll say what I always say. Prohibition never works, it only creates vibrant and violent criminal organizations that thrive, filling the demand with their illegal supply. The fact that there are legitimate, demonstrable medicinal uses for marijuana while drug cartels at our borders commit mass murder and mayhem daily makes this federal prohibition even more ludicrous. Legalize drugs, regulate them, and global crime cartels would implode almost overnight.
Unfortunately, common sense isn't so common any more.
