Another study is promoting the line that raising taxes on cigarettes would stop people smoking, thereby saving millions of lives.
The study reckons that raising taxes would have a three-pronged benefit – saving lives, cutting smoker numbers and generating revenue.
Just one thing: a successful policy will dissuade smokers from continuing with their habit, and the more successful the policy, the fewer smokers remain to pay the tax.
So how can the Government coffers benefit from that?
