Comment on “Do flavouring compounds contribute to aldehyde emissions in e-cigarettes?” by Farsalinos and Voudris

Our purpose is to point out and/or correct inconsistencies and inaccuracies in that paper. Using evidence from several independent studies, we demonstrate that experimental methods used by Farsalinos and Voudris do not fully account for neither particle nor gas-phase aldehydes in e-cigarette aerosols, leading to significant underestimation of aldehyde emissions and risks associated with e-cigarette use.
