As a public health expert with a focus on the impact of tobacco use on health, I can provide you with information on the effects of smoking on life expectancy. It's important to note that the exact amount of life taken off by a single pack of cigarettes is not a straightforward calculation, as it depends on various factors including the number of cigarettes smoked per day, the duration of smoking, and the individual's overall health.

However, studies have shown that smoking significantly reduces life expectancy. On average, a smoker may lose 10 years or more off their life compared to a non-smoker. It's also important to consider that the risk of various diseases, such as lung cancer, heart disease, and stroke, increases with smoking. Each cigarette smoked is estimated to take about 7 to 11 minutes off a person's life, which, when extrapolated over a lifetime of smoking, can add up to a significant reduction in life expectancy.

It's crucial to emphasize that quitting smoking at any age can have immediate and long-term health benefits, and it can increase life expectancy.
