Abstract

Aims
To assess levels of nicotine, nicotine degradation products and some specific impurities in commercial refill liquids for electronic cigarettes.


Design and setting
We analyzed 20 models of 10 of the most popular brands of refill liquids, using gas and liquid chromatography.


Measurements
We assessed nicotine content, content of the known nicotine degradation products and impurities, and presence of ethylene glycol and diethylene glycol.


Findings
The nicotine content in the bottles corresponded closely to the labels on the bottles. The levels of nicotine degradation products represented 0–4.4% of those for nicotine, but for most samples the level was 1–2%. Cis-N-oxide, trans-N-oxide, myosmine, anatabine and anabasine were the most common additional compounds found. Neither ethylene glycol nor diethylene glycol were detected.


Conclusion
The nicotine content of electronic cigarette refill bottles is close to what is stated on the label. Impurities are detectable in several brands above the level set for nicotine products in the European Pharmacopoeia, but below the level where they would be likely to cause harm.

I assumed that vendors had their stock checked at times to check what their juice had in them.

I know it won't be very often, but that's what I thought.

They do womble . And this result shows its working.

Karma.Many thanks for the abstract from the original article. I could not access the original article, as, for me, the links did not work. I wonder if the original report named brand names, although that is unlikely. In my opinion, we can take three positive things from this.

1`. No Ethylene glycol and no diethylene glycol. So no "Anti Freeze". FDA eat your heart out.

2. The worst samples tested showed higher levels of nicotine degradation products that NRT products from Big Pharma. So in the worst case scenario, we have an e cig that instead of being 99% safer than tobacco, is only 98% safer.

3. Big Pharma has had years of experience dealing with nicotine and its degradation products. Thus the technology is out there to extract store and mix nicotine, with minimal degradation products.

It is still very early days for vaping technology. Although vaping is already orders of magnitude safer than smoking, further research will enable us to minimise undesirable by products in both e liquid, and vapour. For instance formaldehyde, an undesirable compound, is found in the vapour of some e cigs. Some devices have as much as 50 times as much compared to others. We need to find out why, and keep it to the lower figure. The same applies to undesirables in e liquid. It is interesting to note that among the degradation products were Anabatine, and anabasine. Both of these compounds are Whole tobacco Alkaloids [WTAs} You normally have to pay extra for those!

Why is it that people only condemn the smoking of cigarettes after they have started to Vape.

I got a great deal of pleasure from smoking cigarettes for approximately 49 years.
I have been Vaping for 10 months and yes, I am enjoying it, but I cannot wipe out, nor would I want to, all these years when cigarettes answered my nicotine cravings.

I simply do not understand the 180 degree switch from the attitude of smokers who for years refused to listen to those who were so anti smoking to now jumping on the soap box alongside them just because they have found an alternative to smoking cigarettes.

Woe the person who stops learning from history, especially their own.

Lobeydosser, The question that you pose at the start of your post is an interesting one. It is a trap that is easy to fall into, and for several reasons, I have to make a conscious effort not to fall into it myself. Firstly, my wife still smokes. I have tried to get her vaping, but very limited success. A lot of our friends who visit are smokers. It would be a big advantage to me if we declared our house as a non smoking house, and it is something my wife would be happy to do, especially during the summer months when it would not be unpleasant to go outside to smoke.

I have avoided doing this for several reasons. When I was a smoker, I felt much more welcome at houses where smoking was the accepted thing. For many years we have not smoked in the front room where we watch TV. We always smoked in the dining room. So if my wife is smoking and it bothers me, I leave the room. It would not bother me much if people smoked in pubs and other public places, especially if the room is a large one. To me it is all about balance and compromise.

I always condemned the smoking of stinkies even when I was smoking them. I was well aware of the damage they were causing me and although I knew it was in my best interests to give up I enjoyed them too much to force myself to quit (I was weak) if not for vaping I would still be a heavy smoker.

I am proud to say that my condemnation worked wonders on my son, he didn't decide to take up smoking (or do drugs which I also drummed into him from an early age) although he does have the odd cigar from time to time.
