In a survey about tobacco use of 250,000 people in 14 nations, findings show more than 50 percent of men smoke or use tobacco, and 11 percent of women are smokers. But the number of people quitting is very low, dropping below 20 percent in some countries like China and India. “We haven’t seen percentages like this since the 1950s in the U.S.,” Gary Giovino, the lead epidemiologist on the study, told NPR. In comparison, about 20 percent of Americans are smokers. Only $1 is spent on smoking prevention programs in poor countries for every $9,100 received in tobacco taxes, so researchers say governments need to invest in anti-smoking campaigns. If not, the medical costs from 850 million smokers globally could be huge.
