This is a very tenuous argument you’re making. Does everyone who’s lost someone to tobacco use get to sue the companies? What about alcohol abuse? Car accidents? What if someone dies in a DUI-related car accident? Can I sue Anheuser AND GM?

did Tony know Tobacco use could cause cancer? Yes. Do chew cans have warnings? Yes. Not sure how they would be liable/should be liable.

Cry me a river.

Look, his death was tragic and the tobacco companies deployed a heartless, immoral policy of manipulating users. But to a degree of being legally or civilly responsible? Adults make choices. These choices can be harmful. But they’re our choices.
