Some lung cells are naturally replaced by new healthy cells in people who quit smoking.
There are approximately 16 million smokers in France, mais selon Tobacco info serviceon average between 400,000 and 500,000 of them stop smoking each year for at least a year.
And the benefits of this weaning are numerous:cell oxygenation returns to normal 8 hours after the last cigarette, Itaste and smell improve 48 hours later,The risk of myocardial infarction decreases two weeks later, cough and fatigue decrease after 3 months. We recover from the breath. We walk more easily. The risk of stroke reaches that of a non-smoker 5 years after the last cigarette.
new lung cells
However, the benefits don’t stop there. A recent study conducted by University College London (UK) and published in the journal Nature demonstrates that some cigarette-damaged lung cells are replaced by healthy cells after smoking cessation. The researchers analyzed the lung biopsies of sixteen people whom they divided into three groups: that of smokers, that of former smokers and finally, the group who had never smoked.
It turned out that these healthy cells that appear after weaning are of the same quality as those of a person who has never smoked. “Once the person quits smoking, cells gradually proliferate in the area to replace the damaged cells, says Peter Campbell, the study’s lead author. It shows that it’s never too late to quit smoking.”
Historic drop in smokers in 2017
Exceptionally, the data from Health Barometer 2017 of Public Health France had demonstrated that the prevalence of daily smoking fell from 29.4% in 2016 to 26.9% in 2017, a decrease of 2.5 points. This represents a million smokers dailies less in a year. This historic decline is part of a strong context of the fight against smoking, with the implementation of important measures such as the sale of neutral packages, the increase in the price of tobacco, the month without tobacco, the reimbursement of substitutes, or even the launch of the Tobacco info service application with Health Insurance.
Figures for 2018 have not yet been revealed. Impossible for the moment to know if it was an exception or if the French really decided to pass a course.
