Smokers of U.S. brand cigarettes may get more bang for their buck in the worst way according to a small study conducted by the Centers for Disease Control and Prevention.
Researchers found U.S. made cigarettes contain more cancer-causing chemicals than some cigarettes brands made elsewhere around the world.
“Not all cigarettes are made alike” says Dr. Jim Pirkle, deputy director for science at the CDC’s National Center for Environmental Health. He says this is the first study to show that “U.S. cigarettes have more of the major carcinogen [TSNAs] than foreign made cigarettes.” TSNAs are “tobacco-specific nitrosamines,” the major cancer-causing substance in tobacco.
126 smokers in five cities – Waterloo, Ontario; Melbourne, Victoria (Australia); London, England, Buffalo, New York, and Minneapolis, Minnesota – were recruited for this study.
They were between the ages of 18 and 55 and smoked at least 10 cigarettes a day for the past year and had been brand loyal for at least three months. The cigarettes smoked by the study recruits represented some of the more popular brands for each country including: Players light and DuMaurier in Canada; Marlboro, Newport Light, Camel Light in the U.S.; Peter Jackson and Peter Stuyvesant in Australia; and Benson & Hedges and Silk Cut Purple in the United Kingdom.
Scientists analyzed more than 2,000 cigarette butts to get the data they are reporting today, says Pirkle.
When researchers compared cigarette brands in the U.S. to those in Canada and Australia, they found three times higher levels of the cancer causing substance in the U.S. smokers’ mouths. The mouth levels are important because they give an indication of what levels if carcinogens are going into the lungs. (Smoking tobacco is a major cause of lung cancer)…
