"Inhalation tobacco smoke by any means, is equally dangerous occupation, "- said Dr. Graham Barr, professor of medicine and epidemiology at the Medical Center of Columbia University, senior author of the study. His work is published in the February issue of the Annals of Internal Medicine.
In the US, the American Cancer Community has been said about the dangers of types of smoking . But a number of fans of nicotine is of the opinion that cigars and pipes are less harmful on the grounds that, during their smoking tobacco smoke allegedly did not inhaled deep into the lungs. Scientists decided to confirm or refute this assertion.
They traced the effect smoking pipes and cigars 3 500 adult citizens aged 48 to 90 years, who were members of other research on the diseases of the cardiovascular system. 9 out of every 100 study participants smoked at times up, and 11 out of every 100 preferred cigars.
Scientists closely monitor the level of cotinine (a specific marker of nicotine intake) blood test to check if they are inhaled tobacco smoke or is it not. Among smokers, cigar and pipe this level was lower than the lovers of cigarettes, but not very much. Lovers of tubes - 20% lower, while the cigar lovers - 10%.
Fans tubes cigars and nearly to the same extent subject ingested toxins present in tobacco smoke, and hence retain not only the risk of developing cancers and chronic obstructive pulmonary disease (COPD). Two of its most common symptoms are emphysema and chronic obstructive bronchitis. In turn, this is the most frequent cause of death among adult Americans.
