Doctors recommend smoking for 40-45 years, because the cardiovascular system is only 15 years after the fall of tobacco. This was shared by participants at the Dallas Medical Forum.
Meredith Duncan of Vanderbilt University in Nashville and her colleagues conducted the first long-standing study on how smoking cigarettes and other nicotine sources affect the health of former smokers and their chances of premature death.
About 9,000 people took part in the study, which was about 27 years old at the beginning of the observation. Volunteers did not suffer from chronic heart disease or vascular system, tuberculosis, and other such lung problems and were generally in good physical and psychological condition.
During 16 years of observation, young people and good health are not guaranteed to be protected from the effects of smoking. For example, the vast majority of infarction and stroke – about 70% – were among former or current smokers, using, for example, one cigarette box a day for 20 years.
The more participants in the experiment smoked, the more often they had problems with the functioning of the lungs and the cardiovascular system. Refusal of "smoke-smoke" at the beginning had a very strong effect on their health, but over time, the rate of preservation of all indicators in the norms has obviously slowed down.
Even after 16 years, doctors note, far from all the negative consequences disappear. This suggests that smokers, if they decide to do so, need to give up their cigarette as soon as possible.
"Five years after stopping smoking, your health has been clearly improved. The risk of stroke, stroke and other heart problems drops by about 38%," Duncan said.
