Electronic cigarette refill liquids: child-resistant packaging, nicotine content, and sales to minors. Some compounds generated from humectants (propylene glycol and glycerol) and flavourings, have been associated with clear airways impact, inflammation, impairment of cardiovascular function and toxicity. Furthermore, there is no safety guarantee since they may harbour potential toxic or irritating properties [5]. Second, e-cigarettes have been described to improve smoking cessation rate only among highly-dependent smokers and not among conventional smokers, suggesting that the individual degree of nicotine dependence plays an important role in this process [97]. Free of the vehicle (gives substance) propylene glycol and similar vehicles.

Thus, devices with rechargeable refills are another issue of concern with e-cigarettes, especially when e-liquids are not sold in child-safe containers, increasing the risk of spilling, swallowing or breathing.

In this line, results from GCMS and HPLC analyses indicated that cinnamaldehyde (CAD) and 2-methoxycinnamaldehyde, but not dipropylene glycol or vanillin, were mainly responsible for the high cytotoxicity of cinnamon-flavoured e-liquids [80]. PubMed Three of the most cytotoxic vapourswith effects similar to those of conventional high-nicotine CS extractsalso caused comparable morphological changes [24].

In fact, they are widely used as alimentary and pharmaceutical products [2]. Thus, assuming 400 to 500 puffs per cartridge, users could be exposed to up to 300g of acrolein. It would seem that future studies should analyse the possible toxic effects of humectants and related products at concentrations similar to those that e-cigarette vapers are exposed to reach conclusive results. 2015;143(2):24255.

When the aerosols of 4 commercially available e-liquids chosen from a top 10 list of Best E-Cigarettes of 2014, were analysed by gas chromatography-mass spectrometry (GCMS) after heating, numerous compounds were detected, with nearly half of them not previously identified [4], thus suggesting that the heating process per se generates new compounds of unknown consequence.

Trends Analyt Chem. Deafness in dogs can also be associated with drugs that have a deleterious effect on the cochlea, Rosychuk says. Krant adds that those who prefer un-preserved products would want to avoid products containing standard preservatives like benzyl alcohol, though it may risk contamination. Other important components in the aerosols include silicate particles from the fiberglass wicks or silicone [89,90,91]. Several compounds detected in e-cigarette aerosols are not present in e-liquids and the device material also seems to contribute to the presence of metal and silicate particles in the aerosols.The heating conditions especially on humectants, flavourings and the low-quality The images or other third party material in this article are included in the article's Creative Commons licence, unless indicated otherwise in a credit line to the material.

In contrast, 80% of the rats exposed to e-cigarette vapor using NC heating units developed clinical acute respiratory distress when a 70W power setting was employed. Some rats received a single e-cigarette exposure for 2h from a NC heating element (60 or 70W); other rats received a similar exposure of e-cigarette vapor using a SS heating element for the same period of time (60 or 70W) and, a final group of animals were exposed for 2h to air.
