TLDR
The present study aims at the determination of the release of volatile organic compounds (VOC) and (ultra)fine particles (FP/UFP) from an e-cigarette under near-to-real-use conditions in an 8-m(3) emission test chamber.Abstract:
Electronic cigarette consumption (vaping) is marketed as an alterna- tive to conventional tobacco smoking. Technically, a mixture of chemicals containing carrier liquids, flavors, and optionally nicotine is vaporized and in- haled. The present study aims at the determination of the release of volatile organic compounds (VOC) and (ultra)fine particles (FP/UFP) from an e-ciga- rette under near-to-real-use conditions in an 8-m 3 emission test chamber. Fur- thermore, the inhaled mixture is analyzed in small chambers. An increase in FP/ UFP and VOC could be determined after the use of the e-cigarette. Prominent components in the gas-phase are 1,2-propanediol, 1,2,3-propanetriol, diacetin, flavorings, and traces of nicotine. As a consequence, passive vaping must be expected from the consumption of e-cigarettes. Furthermore, the inhaled aerosol undergoes changes in the human lung that is assumed to be attributed to deposition and evaporation.read more

Electronic Cigarettes for Curbing the Tobacco-Induced Burden of Noncommunicable Diseases: Evidence Revisited with Emphasis on Challenges in Sub-Saharan Africa
TL;DR: On the whole, if e-cigs were to be introduced in SSA, they should be strictly recommended to current and/or ex-smokers as a method to quit smoking or prevent relapse and never-smoker should be strongly encouraged to avoid using these devices.

Method for estimating the volatility of aerosols using the Piezobalance: examples from vaping e-cigarette and marijuana liquids
TL;DR: In this paper, the Piezobalance instrument is used to measure the accumulated mass on a quartz crystal that can also measure the subsequent loss of mass due to evaporation.

Short-term Pulmonary Effects of Using an Electronic Cigarette: Impact on Respiratory Flow Resistance, Impedance, and Exhaled Nitric Oxide

TL;DR: In this paper, the authors found that using an e-cigarette for 5 min led to an immediate decrease in F ENO within the experimental group by 2.14 ppb (P 5.005) but not in the control group (P5.859), total respiratory impedance at 5 Hz in the experimental groups was found to also increase by 0.033 kPa/(L/s) (P,.001), and fl ow respiratory resistance at 5, 10, and 20 Hz also statistically increased.

TL;DR: The existing evidence on thirdhand smoke (THS) provides strong support for pursuing a programmatic research agenda to close gaps in current understanding of the chemistry, exposure, toxicology, and health effects of THS, as well as its behavioral, economic, and sociocultural considerations and consequences.

TL;DR: In this article, the authors determined nicotine and the nicotine related impurities, that is, cotinine, myosmine, anatabine, anabasine, and β-nicotyrine, in electronic cigarette cartridges, the liquid used to fill the cartridges, and from smoke generated using the electronic cigarette devices.
