Smoking Greatly Reduces Lifespan

Does smoking shorten life expectancy?

Yes. Smoking remains one of the leading preventable causes of death worldwide, reducing lifespan by 10 years on average.

Explanation

Tobacco smoke contains thousands of chemicals, including carcinogens and heavy metals, that cause DNA damage, oxidative stress, and chronic inflammation. Smoking is directly linked to lung cancer, cardiovascular disease, stroke, and COPD.

Even low levels of smoking — fewer than 5 cigarettes per day — significantly increase cardiovascular mortality. Quitting smoking at any age reduces risk, with those who quit before age 40 regaining nearly all of the lost life expectancy.

Practical Emphasis: If you smoke, the single most impactful step for longevity is quitting. Evidence-based strategies include nicotine replacement, medications, and behavioral counseling.

Takeaway (Action Tip)

Quit smoking as soon as possible to reclaim years of life.
