The federal tax hike signed by President Obama in 2009 has led to the decline of U.S. adult smokers.
A USA Today analysis finds three million fewer people smoked last year than in 2009 despite a larger population.
The federal cigarette tax jumped from 39 cents to $1.01 per pack on April 1, 2009, to finance expanded health care for children, according to USA Today.Teens, poor people and those dependent on government health insurance saw a big decline. However, seniors and Hispanics lowered smoking most dramatically. The data also finds about one million adults on Medicaid quit smoking and women quit more than men.
