Flavored cigarettes and new smokeless products are among a new generation of tobacco products that public-health groups say the tobacco industry is using to recruit new customers.

A new report, "Big Tobacco's Guinea Pigs: How an Unregulated Industry Experiments on America's Kids and Consumers," was released this week by the American Cancer Society Cancer Action Network, American Heart Association, American Lung Association and Campaign for Tobacco-Free Kids. Funded by the Robert Wood Johnson Foundation, the report catalogs an "insidious new generation of tobacco products" that are "threatening efforts to reduce tobacco use in the U.S."

Among the emerging hazards highlighted in the report are flavored cigarettes, smokeless tobacco, and cigars, such as Camel cigarettes with lime, coconut, and other flavors that critics contend "mask the harshness of the products and make them appealing to children."

The report also warns about novel smokeless products that "help smokers sustain their addiction in the growing number of places where they cannot smoke;" marketing targeted at women, girls, and other populations; ads with unproved health claims about tobacco products; and undisclosed product designs and ingredients.
