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

Passive exposure to nicotine from e-cigarettes
TL;DR: A procedure based on the use of ion mobility spectrometry (IMS) after liquid-liquid microextraction (LLME) has been successfully employed for the determination of passive exposure to nicotine from cigarette and e-cigarette smoking, and nicotine amount in oral fluids of passive vapers was lower than the average value.

Secondhand Exposure to Electronic Cigarette Aerosol Among US Youths.
TL;DR: Because STEP was designed to detect main effects, only large interaction effects could be identified in these exploratory analyses, and this work focuses primarily on raw interaction P values for evidence of effect modification, although for completeness the authors also present multiple comparison adjusted interaction Pvalues.

TL;DR: Interestingly, e-cigarette particles are smaller than the particles generated from cigarette smoking but have similar human airway deposition patterns.

Public Support for Electronic Cigarette Regulation in Hong Kong: A Population-Based Cross-Sectional Study.
Yee Tak Derek Cheung,Man Ping Wang,Sai Yin Ho,Nan Jiang,Antonio Kwong,Vienna Lai,Tai Hing Lam +6 more
TL;DR: Current stringent measures on tobacco and e-cigarette, and media reports on the harmfulness of e-cigarettes may underpin the strong support for the regulation.

E-cigarette puffing patterns associated with high and low nicotine e-liquid strength: effects on toxicant and carcinogen exposure
Sharon Cox,Leon Kośmider,Hayden McRobbie,Maciej L. Goniewicz,Catherine Kimber,Mira Doig,Lynne Dawkins +6 more
TL;DR: The findings will have important implications for public health messaging regarding the relative risks and subjective effects associated with using high and low strength nicotine e-liquid, and for policy makers regarding regulations on nicotine concentrations in e-liquids.

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.

TL;DR: Short exposure to PG mist from artificial smoke generators may cause acute ocular and upper airway irritation in non-asthmatic subjects and a few may also react with cough and slight airway obstruction.
