Dealers in tobacco and alcohol don't engage in violence, because their products are legal - and so legitimate businessmen are able to enter the markets and outcompete criminals, and because nonviolent means of conflict resolution are therefore available.
It's not the substance that leads to violence, but the illegality. (Alcohol dealers were violent when that drug was illegal.)

Carloads of thieves will be infiltrating thousands of acres of product on countless back roads throughout the region. Sensors will alert security assets (public and/or private) and gunplay will probably ensue.
