It turns out the best way to get people to give up smoking cigarettes is to hit them in the wallet.
A new study found that doubling the cigarette tax in 13 middle-income counties could push as many as 20 percent of smokers to quit.
They crunched he numbers and found the move could save 450 million years of life and $157 billion in medical costs. Researchers also think people in poverty would benefit the most.
72 percent of smokers come from low-income communities and would have the most financial incentive to quit.
