The outlaw them completely. Why should people benefit from taxes on
cigarettes.
I would argue that it makes sense to continue to raise the taxes on
cigarettes to the point where they are so expensive, the market for them
collapses. Unfortunately, the tobacco companies are now concentrating
selling their deadly wares to minors in third world countries. I'm sure
at some point there will be a worldwide ban on the manufacture and sale
of the damned things.
Legal is legal. Besides tobacco built the USA. If there was no tobacco
then we would have been just a very large lumber yard.
