Smokers generally lose about 10 years of life expectancy compared to non-smokers, with studies showing smokers die younger, often losing a significant portion of their potential lifespan due to smoking-related illnesses like heart disease, COPD, and cancer. The exact loss varies, but it can mean around 20 minutes of life lost per cigarette, with quitting at any age significantly improving longevity and health, often adding back years of life.
At age 40 years, the life expectancy was 38.5 years (95% CI: 38.3 and 38.7) for male smokers, 40.8 years (95% CI: 40.6 and 41.0) for ex-smokers, and 43.2 years (95% CI: 42.2 and 42.7) for never-smokers (Table 3).
So there is reason to believe that long-lived smokers represent a biologically distinct group, endowed with genetic variants allowing them to respond differentially to environmental stressors.
On average, smoking reduces your life expectancy by 10 years.
Certain lifestyle habits can negatively affect your physical and mental health, shortening your potential lifespan.
An analysis of the dose response relationship based on combined data of passive smoking, particulate matter from air pollution, and active light and heavy smoking indicates that low levels of tobacco exposure as seen in light smoking (4–7 cig/day) has about 70% of the effect of heavy smoking (≥ 23 cig/day) (29).

When you quit smoking, you may experience the “icky threes”: extra challenges on day 3, week 3, and month 3 of not smoking. In other words, you may experience additional side effects at the third day, third week, and third month after quitting smoking.
“Many people think it's too late to quit smoking, especially in middle age,” said Jha. “But these results counter that line of thought. It's never too late, the impact is fast and you can reduce risk across major diseases, meaning a longer and better quality of life.”
You will have better all-round health: stopping smoking reduces the risk of 50 different illnesses and conditions. Your risk of heart attack will drop by a half one year after quitting. Your risk of cancer will fall. You will set a better example to children and make it less likely that they take up smoking themselves.
Average life expectancy from age 70 was about 18 years in men who had never regularly smoked, 16 years for men who gave up smoking before age 70 but only about 14 years in men still smoking at age 70. Two-thirds of never smokers (65%), but only half of current smokers (48%), survived from age 70 to age 85.
Within one week your sense of taste and smell may have improved. Within three months you will be coughing and wheezing less, your immune function and circulation to your hands and feet will be improving, and your lungs will be getting better at removing mucus, tar and dust.
Try Nicotine Replacement Therapy
Think about trying a short-acting NRT, such as a lozenge or gum, plus long-acting NRT, such as the patch, to get past the craving.
There are usually four stages smokers go through in the process of quitting, which include:
Study finds some individuals have genetic variants that allow them to have long-term exposure to a carcinogen without developing lung cancer.
No, Jennifer Aniston does not smoke cigarettes; she was a heavy smoker for years but successfully quit around 2007, crediting her daily yoga practice and sheer willpower for breaking the habit and becoming a non-smoker for over a decade. She has spoken openly about her past smoking, using it as a motivation for her wellness journey, which includes yoga to manage stress and cravings.
Yes, at least one person, Jeanne Calment of France, is verified to have lived past 120, reaching the age of 122 years and 164 days (1875-1997). She remains the oldest person in history with a fully documented lifespan, making her the only person confirmed to have lived past 120.
Quitting smoking can lead to significant improvements over time. Lung function and health may partially recover, with reduced inflammation and improved cilia function, but some damage, especially from long-term smoking, can be permanent.
Calment continued smoking in her elderly years until she was 117. At "retirement age", she broke her ankle, but before that had never suffered any major injuries. She continued cycling until her hundredth birthday.
King Zog I of Albania, who ruled from 1928 to 1939, was infamous for both his chain-smoking habit and his seemingly indestructible survival streak. He reportedly smoked up to 200 cigarettes a day—so addicted that he would wake himself up in the middle of the night just to light another.
Alcohol: Drinking too much alcohol can dehydrate and damage your skin over time, leading to signs of premature aging. Poor sleep: Studies show that low quality (or not enough) sleep makes your cells age faster. Stress: When you're stressed, your brain pumps out cortisol, a stress hormone.
A peanut butter and jelly sandwich (PB&J) adds about 33 minutes to your healthy lifespan per serving, according to a University of Michigan study that measured life expectancy impacts of over 5,850 foods using the Health Nutritional Index (HNI). This sandwich tops the list for adding time, with nuts and seeds also being highly beneficial (around 25 mins) and processed items like hot dogs subtracting time.
“Smoking is one of the most harmful things people can do to themselves,” Dr. Maniar says. Blood flow drops, slashing oxygen that fuels the heart, which compensates by spiking blood pressure, heart rate and rhythm, and can lead to hardened and narrowed arteries and blood clots causing cardiovascular disease.
During the first few weeks of quitting, try to avoid situations where you will be tempted to smoke and where cigarettes are available. Tell the people you spend time with who smoke that you are quitting smoking. Ask them to support you by not smoking around you and not offering you cigarettes.
