what is the most recent statistics on the prevalence of tobacco use? (SMOKELESS AND SMOKING)?It's for my health homework. I've been searching the web for the last few days and i just can't seem to find anything useful.
i need to know the number of people in the U.S. that smoke and the number of people that chew (chewing tobacco). the internet isn't helping. i can't find a good source or a good statistic. the prevalence of tobacco use..
