American-Made Cigarettes May Be More Cancerous, CDC Finds

Smokers beware : "Made in the U.S.A" may mean have a higher dose of a major carcinogen, according to new research from the Centers for Disease Control and Prevention.

No federal law requires for tobacco companies to label their product's additives.

Smoking cigarettes greatly increases the risk of having cancer no matter where in the world your smokes come from, but a CDC 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.

Levels of nitrosamines, a major cancer for 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.

Only those who smoked the most popular brands in their countries were included in the study, which in the United States included those who preferred Marlboro, Newport, and Camel varieties, according to the study.
