"We know that cigarettes from around the world vary in their ingredients and the way they are produced," said Dr. Jim Pirkle of the U.S. Centers for Disease Control and Prevention, who heads a lab using a mass spectrometer to measure levels of chemicals in people's bodies.
"All of these cigarettes contain harmful levels of carcinogens, but these findings show that amounts of tobacco-specific nitrosamines differ from country to country, and U.S. brands are the highest in the study," Pirkle said in a statement. |
