Decoding E-Cigarette Secrets: Unveiling Saliva and E-Liquid Composition through Fourier-Transform Infrared Spectroscopy.

ABSTRACT: Electronic cigarettes (e-cigs), initially introduced as smoking cessation aids, have given rise to a new wave of nicotine dependence. A critical question that has emerged is the potential adverse effects of e-cig use on oral health, particularly how the vapor emitted from these devices may alter the salivary composition of users. Here, we investigate the salivary composition of e-cig users and analyze the e-liquids (flavorings) using Fourier-transform infrared (FTIR) spectroscopy. Saliva samples were categorized into two groups: e-cigarette users (25 individuals) and nonsmokers/nonusers (25 individuals). Additionally, 26 e-liquid samples used by the e-cig users were collected, with 17 obtained before use and 9 after use. The analysis provided reliable results in distinguishing between the
