Average and standard deviations (SD) were based on three measurements of each variety. Tar, nicotine, and carbon monoxide (CO) values refer to amounts expressed in milligrams/cigarette (mg). All smoke deliveries were measured using the standard International Standards Organisation (ISO) smoking regimen with a 60-second puff interval, 35 ml, puff volume, and a 2-second puff duration.
