Oh, I think that a time will come (likely sooner rather than later) where punitive taxes passed on tobacco products will reach a point of diminishing returns - and at such a point it would be far more profitable for the government to simply sieze the assets of those who would produce, distribute, or consume tobacco products.
I could be wrong - I certainly hope I am.
A pack of cigarettes costs $11.25 in Canada. I don't see any "diminished returns" happening there. I do see poor people even poorer, and in poorer health because they have to eat cheaper, crappy food in order to afford that pack of cigarettes.
But you won't see the tobacco Nazi's in Canada acknowledging that they are actually killing these people faster through excess taxation. They claim instead it's to pay for their health care.
Stalin is alive and well in Canada, and has his foot well in the door in the USA as well.
