Gonna be some riots.
Maybe not. Michigan did this a few years ago and it went fine. But we did it gradually, over a period of 3 months rather than cold turkey. And sanctions for smoking after the ban were held in abeyance for 60 days. Are cigarettes used for prison barter? Yes, they are. But guess what? they were before too! The only difference is now they’ll get sanctioned for possession of tobacco as well as bartering.
