Randomized Controlled Trial
Biomarkers of Exposure Specific to E-vapor Products Based on Stable-Isotope Labeled Ingredients.
An important basis for risk estimation for e-cigarette (e-cig) users is a well-founded dosimetry. The objective of this study was to assess the applicability of stable-isotope e-liquid ingredients for exposure studies in vapers. ⋯ This approach allows the investigations of the absorption of potential PG-, G-, and nicotine-derived vapor constituents (eg, aldehydes and epoxides) by vaping. Appropriate studies are in progress in our laboratory.
