How long does the average male smoker live?

Smoking significantly reduces life expectancy in men. On average, male smokers live 10 years less than male non-smokers. The negative health effects of smoking accumulate over time, so the more a man smokes and the longer he smokes, the greater the impact on his life expectancy. Quitting smoking, especially at younger ages, can significantly increase life expectancy.

What is the life expectancy of a male smoker?

According to data from the Centers for Disease Control and Prevention (CDC), the average life expectancy for a male smoker is:

– Age 30: 45 years
– Age 40: 44 years
– Age 50: 41 years
– Age 60: 37 years

So on average, a 30-year-old male smoker can expect to live to around 75 years old. A 60-year-old male smoker can expect to live to around 77 years old.

Compare this to the life expectancy of a 30-year-old male non-smoker which is around 79 years old, and a 60-year-old male non-smoker which is around 81 years old.

How many years of life does smoking take away?

On average, smoking takes at least 10 years away from a man’s life expectancy. The exact number of years lost depends on the age a man starts smoking and how much he smokes.

According to the CDC:

– Men who smoke less than 1 pack per day lose an average of 10.9 years of life
– Men who smoke 1-2 packs per day lose an average of 13.2 years of life
– Men who smoke more than 2 packs per day lose an average of 14.5 years of life

So heavy smokers who consistently smoke a pack or more per day have life expectancies similar to non-smokers who are 14-15 years older.

Why does smoking shorten life expectancy?

Smoking negatively impacts health and longevity in many ways:

– Greatly increased risk of lung cancer and other cancers
– Increased risk of heart disease and stroke
– COPD (chronic obstructive pulmonary disease)
– Weakened immune system
– Respiratory illnesses like pneumonia
– Poor lung function
– Accelerated aging processes in cells throughout the body

These conditions can develop at earlier ages in smokers and lead to death earlier compared to non-smokers. The carcinogens in cigarette smoke cause direct cellular damage that leads to cancer. Nicotine and carbon monoxide in cigarette smoke are also toxic and damaging.

Does quitting smoking increase life expectancy?

Yes, quitting smoking at any age can significantly increase a man’s life expectancy. According to the CDC:

– Men who quit smoking by age 30 gain 10 years of life expectancy
– Men who quit by 35 gain 9 years
– Men who quit by 40 gain 9 years
– Men who quit by 45 gain 6 years
– Men who quit by 50 gain 5 years
– Men who quit after age 50 still gain increased life expectancy, though less than quitting earlier

So quitting smoking earlier in adulthood provides the greatest benefits for life expectancy. But quitting later in life still improves health and adds years compared to continuing smoking.

Within just 5 years after quitting, ex-smokers have half the risk of lung cancer and heart disease as current smokers. Stroke risk can drop to that of a non-smoker after 2-5 years.

How smoking affects life expectancy by age started

The earlier in life someone starts smoking, the more it shortens their life expectancy.

According to American Cancer Society estimates:

Age Started Smoking Life Expectancy Loss
17 years old 13.3 years
22 years old 12.5 years
27 years old 11.4 years

As shown, men who start smoking in their teens can lose over 13 years of life on average compared to non-smokers. Picking up the habit in the 20s still costs an average of 12.5 years of life. Even starting in the late 20s cuts over 11 years off life expectancy.

The risks are clear – the younger smoking starts, the higher the likelihood of smoking-related diseases and early death.

Smoking rates and life expectancy trends in men

Smoking rates have declined significantly over the past 50 years due to greater public awareness of health risks and anti-smoking campaigns. In 1965, over 50% of adult men were smokers. As of 2018, that rate declined to under 20%.

As smoking has declined, male life expectancy has steadily increased. According to the Social Security Administration, life expectancy for a 65-year-old man was:

– In 1940: 77 years old
– In 1960: 80 years old
– In 1980: 83 years old
– In 2000: 84 years old
– In 2020: 86 years old

So as smoking has become less common, 65-year-old men are now living almost 10 more years on average than in 1940. Quitting smoking played a major role in this increased longevity.

However, recent years have seen a plateauing or decline in US male life expectancy, in part driven by lack of progress against smoking. So continued efforts are needed to reduce smoking rates and improve life expectancy.

Smoking and life expectancy in different countries

Male life expectancy and smoking rates vary significantly between countries based on differences in culture, tobacco policies, and economic factors.

Some patterns seen:

– Developed countries like Australia and Canada with lower smoking rates tend to have higher male life expectancies.
– Developing countries like Indonesia still have very high male smoking rates above 50% and lower life expectancies.
– China and India have huge male smoking populations, pulling down their life expectancies.
– Africa has some of the lowest male smoking rates and is seeing rapidly rising life expectancies.
– The US and Eastern Europe continue to struggle with high smoking rates and lower life expectancies compared to Western Europe.

So lower smoking rates correlate to higher life expectancy, while regions with high smoking have lower longevity. Curbing smoking has increased life expectancy in many countries but remains an issue in others.

Country Male Smoking Rate Male Life Expectancy
Sweden 10% 81 years
Australia 14% 81 years
Canada 16% 80 years
US 17% 77 years
Russia 50% 67 years
Indonesia 76% 69 years


In summary, smoking takes a heavy toll on male life expectancy, costing an average of 10 years of life depending on the intensity of smoking. This is due to the many diseases caused by smoking that lead to earlier death compared to non-smokers. But quitting smoking, especially at younger ages, can significantly regain those lost years of life. As smoking rates have declined over the past 50 years, male life expectancy has steadily risen. However, more progress is needed globally to curb smoking, particularly in the developing world, to maximize longevity in men.
