The Nico Clean Tobacco Card (ca. 1990s)


The NICO Clean Plate was manufactured in Japan, and imported into the U.S. by Marine America, Inc., of Seattle.  


The NICO Clean plate, just like the NAC plate, is a metal plate about the size of a credit card, with a low-grade uranium ore on one side. According to the information on the back of the card, placing the NICO Clean in a package of cigarettes for twenty minutes would "enhance your cigarette smoking while . .  lowering tar and nicotine - 17% average . . .  produce milder smoking with no sacrifice in taste . . .  50% reduction of toluene."
