Many people prefer to buy in duty free or bring from abroad, alcohol and cigarettes. Now they have to be especially on the alert. Scientists from the national Center for control and prevention of diseases USA have found that levels of carcinogens – substances that increase the risk of cancer in cigarettes produced in the United States, much higher than tobacco products manufactured in several other major countries.
Scientists conducted a study, which attracted 126 smokers from two American cities – Buffalo and Minneapolis, as well as London, Melbourne and Waterloo. The age of participants ranged from 18 to 55 years. They all smoked at least 10 cigarettes per day, ITAR-TASS reported. Volunteers were asked to smoke a few cigarettes most popular to their country brands.
Then the researchers analyzed the chemical composition of cigarette butts. One of them consisted of cigarette butts American brands “Marlboro”, “Newport light” and “camel light”, the canadian “players light” and “Dumaria” English “Benson & hedges” and “silk cut purple” and the Australian “Peter Jackson” and “Peter Stuyvesant”. In General, the researchers studied more than 2,000 filters of cigarette butts.
In the end, it turned out that the content of carcinogens in cigarette butts of American cigarettes is three times higher than the concentration of the same substances in smoked cigarettes from other countries. Plus, in the urine of smokers of Americans was revealed in two times more than residents of other countries, typical tobacco nitrosamines (substances with carcinogenic properties).
Turns out Smoking Americans are getting a dose of carcinogens in two times exceed the amount received by smokers from other countries. The representative of the national Center Dr. Jim Pirkle warns of particular hazards of American cigarettes. However, “if you want all of these substances have not worked – quit Smoking,” he advises.
