Kent widely touted its "famous micronite filter" and promised consumers the "greatest health protection in history". Sales of Kent skyrocketed, and it has been estimated that in Kent's first four years on the market, Lorillard sold some 13 billion Kent cigarettes. From March 1952 until at least May 1956, however, the Micronite filter in Kent cigarettes contained compressed carcinogenic blue asbestos within the crimped crepe paper.[3][4] It has been suspected that many cases of mesothelioma have been caused specifically by smoking the original Kent cigarettes, and various lawsuits followed over the years because of it.[5][6][7] Lorillard quietly changed the filter material from asbestos to the more common cellulose acetate in mid 1956.[3] Kent continued to grow until the late 1960s, then began a long, steady decline as more filtered cigarette brands promising even lower tar (and appealing to smokers' desires for a "safer" smoke) were introduced.
