Measurement of the quantities of tar, nicotine, and carbon monoxide (TNCO) in the mainstream smoke of cigarettes currently marketed in the U.S. will provide important information about these constituents. The purpose of this project is to determine the differences between TNCO yields generated under the smoking regimen defined by the International Standards Organization (ISO) and yields generated under a modified version of the ISO regimen. Researchers will test approximately 35 different cigarette brands using smoking machines using the ISO and modified ISO smoking regimens; researchers will determine whether there are differences in TNCO smoke yields between these two regimens.  (Project completed in 2015.)
