Once thought to be relatively harmless and pushed as a ‘past time’ of sorts even by the medical community, scientific studies have proved beyond a doubt that tobacco use – and smoking, in particular – poses major health risks to humans.
In fact, one of the most recent bodies of research, published online by JAMA Internal Medicine, found that the proportion of cancer deaths that are attributable to smoking cigarettes contributes to nearly 40 percent of deaths in some regions of the country.
The study found that there were higher percentages of cancer deaths from smoking, generally, in the South, where about 4 in 10 deaths of men were attributable to the habit.
Currently there are about 40 million adults who still smoke cigarettes in the United States, Medical News Today reported, citing the study. Also, smoking remains the most preventable cause of death from cancer and a host of other diseases, all of which have been linked to habit.
The South is the hardest hit region for smoking-related cancer deaths
In all, smoking cigarettes is responsible for an estimated 28.7 percent of all cancer deaths in the United States, in adults aged 35 and older in 2010. However, there are no state-by-state estimates, Medical News Today noted.
