U.S. has success in preventing smoking deaths

Anti-smoking measures adopted over the past 50 years in the United States have prevented 8 million early deaths and extended lifespans by two decades, though a rise in the global population has kept the number of smokers and the tobacco market growing. About 5.3 million men and 2.7 million women live longer thanks to tobacco control, said one of six studies on the topic published in the Journal of the American Medical Association. What's more, life expectancy at age 40 for U.S. men and women has increased 2.3 years and 1.6 years.
