There are mountain passes in Oregon with posted signs during winter that say "winter tires or chains required". I'm not sure if you can actually be cited by an officer for not having them, but certainly you are a hazard to everyone on the road if you don't have them :)
That's the real problem: selling drugs works! Forming a cartel to produce and distribute addictive products, killing anyone who gets in your way? It's effective! You're never going to convince someone to stop killing people and dumping their bodies into culverts when they're making money. It's just not reasonable to expect that, or do anything about it.
