Tobacco Product Standard for N-Nitrosonornicotine Level in Finished Smokeless Tobacco Products

Краткое содержание

The Food and Drug Administration (FDA) is proposing a tobacco product standard that would establish a limit of N-nitrosonornicotine (NNN) in finished smokeless tobacco products. FDA is taking this action because NNN is a potent carcinogenic agent found in smokeless tobacco products and is a major contributor to the elevated cancer risks associated with smokeless tobacco use. Because products with higher NNN levels pose higher risks of cancer, FDA finds that establishing a NNN limit in finished smokeless tobacco products is appropriate for the protection of the public health.
