Smoking a single cigarette life expectancy?

The exact reduction in life expectancy from smoking a single cigarette is difficult to determine, as there are numerous factors that can influence an individual's lifespan. However, research suggests that smoking in general has significant negative impacts on health and longevity.

According to the Centers for Disease Control and Prevention (CDC), smoking is the leading preventable cause of death in the United States, responsible for over 480,000 deaths annually. Smoking can lead to a range of health problems, including cancer, heart disease, stroke, lung diseases, and more.

While the impact of a single cigarette may be relatively small, the effects of consistent smoking accumulate over time. Each cigarette increases the risk of developing smoking-related illnesses, and the more a person smokes, the greater the risk.

In general, smoking reduces life expectancy by several years. The CDC estimates that smokers lose an average of 10 years of life compared to non-smokers. However, this number can vary depending on the individual and their smoking habits.

It is important to note that quitting smoking can help improve health and extend lifespan, regardless of how long a person has been smoking. The benefits of quitting smoking can be significant, even for those who have smoked heavily for many years.
