Overall life expectancy is also reduced in long term smokers, with estimates ranging from 10 [22] to 17.9 [23] years fewer than nonsmokers. [24] About one half of long term male smokers will die of illness due to smoking. [25] The association of smoking with lung cancer and COPD are among strongest, both in the public perception and etiologically.
The analysis, which will be published in the Journal of Addiction, states the average of 20 minutes of life expectancy lost for each cigarette “is time that would likely be spent in relatively ...
Similarly, in the United States, life expectancy for smokers is estimated to be at least 10 years shorter than for nonsmokers, according to the US Centers for Disease Control and Prevention.
6.5 years = 2,374 days and 56,976 hours, or 3,418,560 minutes. 5,772 cigarettes per year for 54 years = 311,688 cigarettes. 3,418,560/311,688=11 minutes per cigarette.
The report concludes that cigarette smoking damages health. It finds that cigarette smoke is the primary cause of chronic bronchitis, and smokers had a 70% increase in age-corrected mortality rate. Smoking is also correlated with emphysema and heart disease, and increases the chance of developing lung cancer by 10 to 20 times.
The LD 50 of nicotine is 50 mg/kg for rats and 3 mg/kg for mice. 0.5–1.0 mg/kg can be a lethal dosage for adult humans, and 0.1 mg/kg for children. [19] [20] However the widely used human LD 50 estimate of 0.5–1.0 mg/kg was questioned in a 2013 review, in light of several documented cases of humans surviving much higher doses; the 2013 review suggests that the lower limit causing fatal ...
In 2000, data published in The BMJ estimated one cigarette would cost a person 11 minutes of their life.
Some studies from the 1990s found that when people stop smoking, depressive symptoms such as suicidal tendencies or actual depression may result, [188] [207] although a recent international study comparing smokers who had stopped for 3 months with continuing smokers found that stopping smoking did not appear to increase anxiety or depression.
