Smoking is a bad habit wherever you are, but it might be even more dangerous in the U.S.
A Centers for Disease Control and Prevention study finds that those puffing on American-made products may receive up to three times the level of carcinogenic nitrosamines as those smoking foreign brands, ABC News reported.
Levels of nitrosamines, a major cancer-causing agent in cigarettes, absorbed by daily smokers in a 24-hour period were compared for 126 smokers in the U.S., Canada, U.K., and Australia.
"People smoking the U.S. brand cigarettes [we tested] received a level of this carcinogen in their mouth and lungs that was three times higher compared to smokers in Canada and Australia," says Dr. James Pirkle, deputy director for science at the CDC's National Center for Environmental Health.
