I'm pretty sure cancer was the basis of the lawsuits, not addiction.When they put addictive substances into the blend, they become culpable to a conspiracy to make people addicted to nicotine.
That is the basis for the lawsuit against them.
My point is this... it's common knowledge that folks in dwelling and other fires often die of smoke inhalation rather than burns. So why would you intentionally inhale smoke, and then not expect negative results?
Maybe it's just me...
