Vapor Phase Removal and Nicotine Augmentation with All Air Dilution Cigarettes
Abstract
Study describing use of air dilution as an alternative to the addition of nicotine for low tar cigarettes with enhanced nicotine (as part of the nicotine augmentation project). Lists removal efficiencies for smoke constituents using an all air dilution cigarette with no cellulose acetate filter plug. Other findings include increase in nicotine to tar ratio and increase in smoke pH, indicating potential use for all air dilution cigarette for low gas phase delivery. However, at tar levels below 6 mg, difficulties in pressure drop and lighting occur.
