Scientists: “light” cigarettes may increase the risk of cancer
Cigarette with a ventilated filter, which is considered less harmful, in fact can increase the risk of cancer, scientists believe. The growing popularity of such cigarettes over the past decade coincides with an increase in the number of cases of adenocarcinoma — the most common form of lung cancer, say researchers from Ohio state University.
Filter ventilation does not reduce the amount of harmful substances inhaled by the smoker, but only dilutes them with air. However, in the 60-ies, when this filter was invented, the advertising company brought it to market as “more healthy” alternative to cigarettes with a filter.
As more and more people in the world with years refused from Smoking, growing demand for “light” cigarettes, says one of the study authors Peter shields.
At the same time, on the background of a General decline in the incidence of lung cancer, the number of cases of adenocarcinoma lung cancer, which scientists associate with “light” cigarettes — continues to grow.
“Our data show a clear Association between the use of ventilation holes in cigarette filters and a rising incidence of adenocarcinoma that we have seen over the last 20 years. Of great concern is that these vents are used in almost all of the cigarettes that are Smoking today,” says shields.
Perforated filter does not reduce the amount of harmful substances in tobacco smoke and enables the smoker to make great torque, which on the contrary leads to the fact that the body gets a greater amount of carcinogens, scientists say.
“The tobacco in cigarettes with ventilated filter burns differently, forming more carcinogens, and the smoke penetrates deeper into the lungs, in those parts of the body, where usually is adenocarcinoma,” says shields.
Today in the United States and Britain prohibited to label cigarettes as “light” or “low tar content”, but scientists believe that this is not enough. They advocate a complete ban of the use of a perforated filter.
