> Zyn and vapes

Those don't contain tobacco, nor nicotine derived from tobacco. I'd be surprised if tobacco farming was still lucrative, except maybe the fine stuff for cigars, but that was always a relatively small market compared to cheap cig tobacco.

I'd be surprised if any one selling tobacco products were swimming in cash. Single use vapes are expensive compared to cost but there are tons of sellers. If you buy vape juice you can get something like the equivalent of 100 packs of cigarettes for $15. Vape shops jack up all the prices but there are 5 shops on every street and they always seem empty and I'm convinced they are mostly just laundering money.

Agreed. Synthetic nicotine has been around for awhile as well, which is much cheaper than sourcing the old fashioned way.
