Mortality

Smoking is the cause of about 5 million deaths per year. This makes it the most common cause of preventable early death. One study found that male and female smokers lose an average of 13.2 and 14.5 years of life, respectively. Another measured a loss of life of 6.8 years. Each cigarette that is smoked is estimated to shorten life by an average of 11 minutes, though this may vary slightly on the contents and brand. At least half of all lifelong smokers die early as a result of smoking. Smokers are three times more likely to die before the age of 60 or 70 than non-smokers.

In the United States, cigarette smoking and exposure to tobacco smoke accounts for roughly one in five, or at least 443,000 premature deaths annually. To put this into context, ABC's Peter Jennings (who would later die at 67 from complications of lung cancer caused by life-long smoking) famously reported that in the US alone, smoking tobacco kills the equivalent of three jumbo jets full of people crashing every day, with no survivors. On a worldwide basis, this equates to a single jumbo jet every hour.

A 2015 study found that about 17% of mortality due to cigarette smoking in the United States is due to diseases outside of those commonly linked with smoking, and that official estimates may therefore be significantly underestimating the number of deaths currently being attributed to smoking.

It is estimated that there are between 1 and 1.4 deaths per million cigarettes smoked. In fact, cigarette factories are the most deadly factories in the history of the world. See the below chart detailing the highest-producing cigarette factories, and their estimated deaths caused annually due to the health detriments of cigarettes.

According to WHO, 27137 annual deaths are attributed to tobacco use in Nepal.
