Due to their popularity, however, many rules and regulations have been put in place to help deter their use in younger generations as they have been proven to cause detrimental health effects similar to conventional cigarettes. In this study, a gas chromatography-mass spectrometry (GC/MS) method was utilized to assess the reported and actual components of the electronic cigarette liquids (e-liquids) in two flavors of two favored manufacturers, Juul and Crave Disposable, as well as to further compare the components within similar flavors from the different brands. Virginia tobacco by Juul and tobacco by Crave Disposable were compared and found to have similar components such as benzoic acid and nicotine to both the reported components and each other. Menthol by Juul and clear by Crave Disposable were compared and found to have similar components such as benzoic acid, menthol, and nicotine, to both the reported components and each other as well as an additional component, n-ethyl-4-hydroxypiperidine, an artifact of benzoic acid. Due to the increase of regulations and restrictions on components allowed in e-liquids, each similar e-liquid flavor from each manufacturer was found to be comparable in composition.en-USAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/ToxicologyE-LiquidElectronic cigarettesElectronic liquidFlavorNicotineVapingThesis/Dissertation2023-02-140000-0002-8816-3191
