Description
In recent years, electronic nicotine delivery systems (ENDS), commonly known as electronic cigarettes (ECs), have gained popularity, particularly among adolescents (Cooper, 2022). • The core component of these devices is e-liquids which contain nicotine, propylene glycol, vegetable glycerin, flavoring, and other chemicals (Cheng, 2014; Sassano, et al., 2018). • The FDA regulates manufacturing, importing, packaging, labelling, advertising, promotion, sale, and distribution of ENDS, but they do not check the accuracy of reported information. • Studies have consistently shown that labelled nicotine concentration and actual concentration can range from as little as 35% less nicotine to as much as 52% greater nicotine (Raymond, et al., 2018; Alhusban & Ata, 2020). • Due to the potential variation in nicotine concentration, it is vital to establish a preparation technique that limits variation in nicotine concentration. • In the present study we utilized mass preparation as a method to limit variation in nicotine preparation. We are comparing two different types of analysis, HPLC vs. GCMS, to ensure method accuracy. • This study is the first in a series investigating variation in nicotine concentration results and the next study we will be investigating the potential impact of flavoring on the concentration of nicotine detected in ENDS and ECs.
