Effects of Device Settings and E-Liquid Characteristics on Mouth-Throat Losses of Nicotine Delivered with Electronic Nicotine Delivery Systems (ENDS).

The study by hosseini et al. compares the size distribution of aerosols generated by e-cigarettes at body temperature and humidity in a mouth-throat model to that in room conditions. The study also examines the effect of e-liquid composition, including PG:VG ratio, nicotine form, and flavorants, on the size data. The size data is presented in Table 5 for various e-liquid compositions as described in Table 1. Statistical analyses were performed to compare the size data for commercial vs customized e-liquids, e-liquids with different PG:VG ratios, e-liquids with the same PG:VG ratios but different flavors, and e-liquids with the same PG:VG ratios and flavor but different nicotine forms. The study aims to contribute to the understanding of the health risks associated with e-cigarette use.This study examines the effect of device settings and e-liquid characteristics on collection efficiency. The researchers compared Dv10, Dv50, and Dv90 data at the mouthpiece vs throat for seven e-liquids and found significant differences with p-values of 0.5, 0.5, and 0.5, respectively.
