Any time a smoking ban is on the cards people invariably seem to trot out the argument that the pollution from smoking is negligible when compared to pollution from motor vehicles.
I'm inclined to believe that is a valid argument.
However!
If motor vehicles were banned tomorrow I imagine that the effect on the world economy would be massive.
If smoking was banned tomorrow I believe the effect on the world economy would be significantly less.
I realise that governments would lose a source of income from taxation.
In the UK I would hazard a guess that the loss of taxation would be more or less balanced out by the reduction in costs to the NHS of caring for those suffering the very serious ill effects that arise from smoking.
Also healthier people = more work days = more income tax paid to the government.
Or am I being too simplistic?
ETA - I also can't see any real, useful benefit for anybody in smoking.
