I'm not talking about shaming. But I think it's a right thing to penalize people who smokes, at least financially. How else ? It is the same thing for marijuana I believe.

If both the supply and demand are high, but the health effect are bad, it's fair to introduce a tax.

It doesn't have a lot to do with regressive tax policies, which are based either on income or wealth, you can't apply that to tobacco products.

Next time are we going to argue about the tax on heroin once it's legal ? Public health policies are tricky because markets force are involved with addiction forces.
