A research carried by U.S. Centers for Disease Control and Prevention (CDC) revealed that cigarette brands produced by U.S. tobacco companies in comparison with cigarettes brands produced in other countries, possess higher levels of toxic chemicals that provoke cancer.
As concluded the CDC research team, the USA tobacco mixture comprises more cancer-causing substances than cigarettes manufactured in Australia, Canada, and the United Kingdom.
In the course of research scientists examined 126 smokers from Australia, Canada, and the United Kingdom. The examined smokers were aged 18-55 years and smoked daily around 15 cigarettes for the last 12 months.
The examined participants were devoted to “American Blend” cigarette brand for more than 3 months. The CDC team hasn’t specified what kind of U.S. brand was used, only stating that it as a popular “American blend”.
Among the brands that appeared in research were Players in Canada produced by Imperial Tobacco, Lorillard’s Newport, Marlboro produced by Philip Morris USA, UK’s Benson & Hedges and Winfield in Australia produced by British American Tobacco.
More than 2000 cigarettes butts were examined by the research team.
After examining cigarettes made in Canada, USA, Australia, and the United Kingdom, the scientists found out that tobacco products from United States identifying as ‘American Blend’ contain high levels of tobacco-specific nitrosamines and cancer-causing chemicals that favor the development of malignant tumors.
Whereas cigarettes made in other countries contained other types of tobacco that have shown lower levels of carcinogens.
In order to calculate the levels of TSNA, the researches measured the quantity of these substances in cigarettes butts, in saliva and urine of those smokers who participate in the research. They came to conclusion that smokers of cigarettes made in USA were exposed to three-time higher levels of carcinogens than smokers who prefer cigarettes brand from other countries.
“It is obvious that cigarette brands that are produced in different countries differ in methods of fags’ production and also in applied ingredients”, said Dr. James Pirkle, vice manager for science at CDC’s National Center for Environmental Health. “All of those tested tobacco products demonstrate high amount of cancer-causing substances, although, the study shows that the levels of tobacco-specific nitrosamines differ from nation to nation, and cigs made in U.S. contain the highest levels of this substances” the scientist concluded.
The obtained data are published in the latest ‘Cancer Epidemiology, Biomarkers & Prevention’ Journal.
The present research is one more proof showing the severe consequences of tobacco usage,
that is the major cause of preventable deaths all around the world, tacking the lives of more than
5 million people per year.
According to the recent report presented by the World Health Organization, more than 8 million of people will die till 2030 if tobacco usage is not reduced.
