TL;DR: Analyses of THC-containing product samples by FDA and state public health laboratories have identified potentially harmful constituents in these products, such as vitamin E acetate, medium chain triglyceride oil (MCT oil), and other lipids.
Journal ArticleDOI
Quantitation of urinary volatile nitrosamines from exposure to tobacco smoke.
Tiffany H. Seyler,Jenny Gi Yae Kim,James A. Hodgson,Elizabeth A. Cowan,Benjamin C. Blount,Lanqing Wang +5 more
TL;DR: The levels of all six volatile nitrosamines were reported for the first time in urine specimens collected from smokers and nonsmokers, with smoking status determined by urinary cotinine measurement.
Journal ArticleDOI

TL;DR: In this article, the authors developed and validated a quantitative method to measure squalene and squalane in EVP aerosol emissions, and validated parameters include measurement repeatability (SQA and SQE %RSD).
Journal ArticleDOI
The Quantitation of Squalene and Squalane in Bronchoalveolar Lavage Fluid Using Gas Chromatography Mass Spectrometry
TL;DR: A quantitative method to measure SQE and SQA in bronchoalveolar lavage fluid to assess if these chemicals accumulate in lung epithelial lining fluid after inhalation and to evaluate the potential toxicity of SQA and SQE chronically inhaled from EVPs.
