As a health professional with extensive experience in epidemiology and public health, I am well-versed in the impact of smoking on human health. The question of how long one can live if they smoke cigarettes is complex and multifaceted. It involves a variety of factors including genetics, lifestyle choices, and the environment. However, it is widely accepted that smoking significantly reduces life expectancy.

Smoking and Life Expectancy

First and foremost, smoking is the leading cause of preventable death worldwide. It is associated with a myriad of health issues, including but not limited to lung cancer, chronic obstructive pulmonary disease (COPD), heart disease, stroke, and various other cancers. The harmful chemicals in tobacco smoke damage the body's cells, leading to the development of these diseases.

Statistical Evidence

According to the data you've provided, if you are a long-term smoker, on average, your life expectancy is about 10 years less than a non-smoker. This is a significant reduction and highlights the profound impact of smoking on longevity. In the UK, the statistics are stark: **about 8 in 10 non-smokers live past the age of 70**, whereas only **about half of long-term smokers live past 70**. These numbers underscore the importance of smoking cessation for those who wish to maintain a healthy life span.

Factors Influencing Life Expectancy

It's important to note that life expectancy is not solely determined by smoking. Other factors such as diet, exercise, access to healthcare, and socioeconomic status also play a crucial role. However, smoking is a modifiable risk factor, meaning that by quitting, individuals can improve their health outcomes and potentially increase their life expectancy.

The Benefits of Quitting Smoking

Quitting smoking has immediate and long-term benefits. Within 20 minutes of quitting, heart rate and blood pressure begin to drop. Within 12 hours, carbon monoxide levels in the blood drop to normal. Over time, the risk of heart disease and stroke decreases significantly. After 5 years of quitting, the risk of lung cancer is significantly reduced, and after 10-15 years, the risk of dying from lung cancer is about half that of a smoker.

Conclusion

In conclusion, while it is difficult to provide a precise number for how long one can live if they smoke, the evidence is clear that smoking has a detrimental effect on life expectancy. The sooner one quits smoking, the better their chances of improving their health and extending their life. It is always advisable to seek support from healthcare professionals when attempting to quit, as they can provide guidance, resources, and assistance tailored to the individual's needs.
