Characterization of E-cigarette coil temperature and toxic metal analysis by infrared temperature sensing and scanning electron microscopy - energy-dispersive X-ray.

Introduction: Electronic cigarettes (e-cigarettes) have rapidly evolved since their introduction to the U.S. market.

The Analysis of Aerosolized Methamphetamine From E-cigarettes Using High Resolution Mass Spectrometry and Gas Chromatography Mass Spectrometry.

The use of electronic cigarettes (e-cigs) has expanded from a nicotine delivery system to a general drug delivery system. The internet is rife with websites, blogs and forums informing users how to modify e-cigs to deliver illicit drugs while maintaining optimal drug delivery of their device. The goal of this study was to qualitatively identify the presence of methamphetamine in the aerosol produced by an e-cig and to quantitatively assess the effect voltage on the concentration of aerosolized methamphetamine.

Identification of MDMB-FUBINACA in commercially available e-liquid formulations sold for use in electronic cigarettes.

MDMB-FUBINACA (aka MDMB(N)-Bz-F), chemical name Methyl (S)-2-(1-(4-fluorobenzyl)-1H-indazole-3-carboxamido)-3,3-dimethylbutanoate, a designer drug or a new psychoactive substance (NPS), was identified in three commercially available e-liquids formulated for electronic cigarette use. The e-liquids were evaluated using direct analysis in real time ion source attached to a time of flight mass spectrometer (DART-MS) and gas chromatograph mass spectrometer (GC-MS) to identify active ingredients/drugs, flavorants, and other possible constituents. The e-liquids were also evaluated for alcohol content by headspace gas chromatography with flame ionization detector (HS-GC-FID).
