How would tobacco farmers be affected if tobacco was banned?
They would lose a lot of money that they get for selling tobacco
It's highly unlikely in the US. Most tobacco farmers produce several different crops, of which tobacco is usually a minor one, so they probably would not need new jobs in the first place. Secondly, the US government is having a difficult time finding or creating new jobs for the many thousands of people displaced by the recent economic downturn.
If tobacco smoking were discovered tomorrow, it is unlikely that any responsible government anywhere in the world would allow tobacco to be manufactured, much less advertised, but legislators cannot now outlaw a product to which a quarter of the adult population is addicted, and no-one would seriously suggest that they should
Tobacco is a back-bone agricultural product for many states in the southern part of the US, without which many people, counties and state economies would suffer dramatically. It has also been said that tax on tobacco is such a significant component of tax revenue throughout the US, that without it, all local economies would also suffer dramatically. In sum, tobacco is a major money maker for all the members of its distribution channel.
