The giant corps are the ones massively involved in the black market :(

It’s probably not realistic to say no upside, as people usually do stuff for reasons even if it’s terrible overall. Like a bizarrely high proportion of people with schitzophrenia take nicotine so there probably is something it’s doing that helps in the moment.

There’s gonna be a market one way or the other. IMHO the government should step in to make it tightly controlled and low profit (if not nationalised). Also we should lynch everyone who’s ever taken a dollar of tobacco money but idk how broad support for that is.
