Estimating tar and nicotine exposure: Human smoking versus machine generated smoke yields

Objective Determine human smoked (HS) cigarette yields of tar and nicotine for smokers using their own brand in their everyday environment. Method A robust, filter analysis method was used to estimate the tar and nicotine yields for 784 subjects. Seventeen brands were chosen to represent a wide range of styles: 85 and 100 mm lengths; menthol and non-menthol; 17, 23, and 25 mm circumference; with tar yields [Federal Trade Commission (FTC) method] ranging from 1 to 18 mg. Tar bands chosen corresponded to yields of 1–3 mg, 4–6 mg, 7–12 mg, and 13+ mg. Results A significant difference (p
