Tobacco must be banned. Yes or No.

Millions of people consuming it, getting addicted to it, damaging their body, increasing pressure on health sector, people of all age has easy access to it so might b there is no control over will of an indivisual and get influenced by their surroudings.
Suppose tobacco banned instantly what will happen?
Millions of people mostly farmers, the people earning by putting a stall beside the road and many others will loose their daily earnings, there will be a huge pressure on an indiviual and the government due to this job crisis, other than this the addicted consumers will try to find many ways to get it and there will be an increase in the black and illegal marketing, may b they shift to other drug products.
So, not banning tobacco is damaging the people every second and banning it will cause both huge merit and demerit impact. The way I think to curve it is first shifting major people from this sector to other, mass campaign of awareness and then ban the tobacco.
