This very same thing has been going on for two decades with underage tobacco users who are caught using (or even possessing) tobacco products at high schools in all 50 states, and everywhere in about half of the states (that have made it illegal for youth to use or possess tobacco products).
Back in 1999, I was featured on a CBS NEWS 60 Minutes segment exposing that the tobacco industry was lobbying for laws to ban and penalize youth who were caught using or possessing tobacco products. The segment also showed a Florida Judge holding "tobacco court" where he lectured and threatened to fine or throw high school students in jail if they didn't quit smoking.
During the past several years, ANTZ have aggressively lobbied hundreds of universities to ban all tobacco use (and vaping) on the entire campuse, with somewhat similar punitive sanctions for violators. But I'm not aware of any university students (at any university) who were caught violating these "NO USE" policies actually being fined, suspended, expelled or required to attend classes, counseling or tobacco cessation programs. In sum, these no tobacco use policies at universities are unenforceable, and are not enforced.
