Cancer-causing chemicals thought to be absent from smokeless tobacco products are present in moist snuff, a mouth tobacco mostly used in North America. At an American Chemical Society meeting, Irina Stepanov at the University of Minnesota reported that a dose of moist snuff delivers the same quantity of polycyclic aromatic hydrocarbons as five cigarettes.
