The next time you light a cigarette, consider this: according to a recent study conducted at University College London (UCL), men lose an average of 17 minutes of life with each cigarette, while women lose 22 minutes. This new research highlights the devastating effects of smoking and offers even grimmer statistics than previously thought.

Earlier estimates suggested that each cigarette reduced a smoker's lifespan by 11 minutes. However, these updated findings indicate the toll of smoking may be significantly greater.

Smoking Shortens Healthy Years

The research emphasised that quitting smoking at any age brings immediate and long-term health benefits. "Women in 1996 smoked an average of 13.6 cigarettes per day. Therefore, other things being equal, this would lead to an increase in the estimated loss of life expectancy per cigarette to 20 minutes overall: 17 minutes for men (1110/6.5) and 22 minutes for women ((1111/6.5)*(15.8/13.6))," the study stated.

“Studies suggest that smokers typically lose about the same number of healthy years as they do total years of life. Thus smoking primarily eats into the relatively healthy middle years rather than shortening the period at the end of life, which is often marked by chronic illness or disability," the study authors said. To understand this better, the authors explained that a 60-year-old smoker will typically have the health profile of a 70-year-old non-smoker. 

“People generally know that smoking is harmful but tend to underestimate just how much. On average, smokers who don't quit lose around a decade of life. That's 10 years of precious time, life moments, and milestones with loved ones," Dr Sarah Jackson, a principal research fellow at UCL was quoted as saying by the Guardian.

Urgency To Quit Smoking

The authors emphasised the urgency to quit smoking. "A person smoking 10 cigarettes per day who quits smoking on the 1 January 2025 could prevent loss of a full day of life by the 8th of January, a week of life by the 20th of February, and a month by the 5th of August." 

In India, 28.6% population currently consume tobacco either in smoke or smokeless form, including 42.4% of men and 14.2% of women, according to the National Family Health Survey (NFHS). The northeastern states of India have a higher share of female population identified than any other Indian state. Mizoram recorded the highest share of female smokers. 

Effects of Smoking on Women

Smoking puts women at higher risk of cervical cancer, according to the American College of Obstetricians and Gynecologists (ACOG). A Danish study published in the 1999 issue of the Journal of the National Cancer finds that premenopausal women who smoke are six times more likely to develop rectal cancer than those who don't.

Smoking increases the risk of miscarriage among women by 39 percent. "When you smoke during pregnancy, you poison the fetus," says Benjamin Sachs, professor of obstetrics and gynaecology at Harvard Medical School. The breast milk of a smoker can carry traces of nicotine. 

Women are more likely to develop chronic obstructive pulmonary disease (COPD) than men, and at a younger age. Smoking is responsible for 80% of COPD deaths in women each year.
