Formaldehyde In Juice?

I have an appointment with my doctor tomorrow, and he had asked that I try to quit vaping and switch to nicotine gum because ecigs create formaldehyde in the lungs, which is terrible for you. I know many of you have dealt with this BS, so here's a short, easy-to-read article by a doctor explaining exactly why these studies are ridiculous and misleading. There is much more in-depth stuff out there, but for something by a medical professional that is still very scientific but still easy enough to approach that people will actually read it, I think it's pretty darn good.

The deception of measuring formaldehyde in e-cigarette aerosol: the difference between laboratory measurements and true exposure  

Ok I'm hoping I don't get heat for these questions/statements but educating ones self especially with something that is still very new is important to me.

1. Read some articles on how there is second hand vape similar to cigarettes (99% better mind you) what are your thoughts? Vaping may not be as safe as smokers think, research suggests | Society | The Guardian

2. Formaldehyde found in builds running at high watts/voltage? But 0% at low/normal builds, what i can't seem to find is whats considered to high for a Mechanical Mod or even for a V/W, V/V Setup? My normal build for a mech mod is twisted single coil 24 gauge 6-7 wraps, usually gets about 0.28 ohms and single coil 8 wraps of 24 gauge puts out 0.73 ohms on my flavor builds.

the short story ......

Background and aims

Aldehydes are emitted by electronic cigarettes due to thermal decomposition of liquid components. Although elevated levels have been reported with new-generation high-power devices, it is unclear whether they are relevant to true exposure of users (vapers) because overheating produces an unpleasant taste, called a dry puff, which vapers learn to avoid. The aim was to evaluate aldehyde emissions at different power levels associated with normal and dry puff conditions.

Design
Two customizable atomizers were prepared so that one (A1) had a double wick, resulting in high liquid supply and lower chance of overheating at high power levels, while the other (A2) was a conventional setup (single wick). Experienced vapers took 4-s puffs at 6.5 watts (W), 7.5 W, 9 W and 10 W power levels with both atomizers and were asked to report whether dry puffs were generated. The atomizers were then attached to a smoking machine and aerosol was trapped.

Setting
Clinic office and analytical chemistry laboratory in Greece.

Participants
Seven experienced vapers.

Measurements
Aldehyde levels were measured in the aerosol.

Findings
All vapers identified dry puff conditions at 9 W and 10 W with A2. A1 did not lead to dry puffs at any power level. Minimal amounts of aldehydes per 10 puffs were found at all power levels with A1 (up to 11.3 µg for formaldehyde, 4.5 µg for acetaldehyde and 1.0 µg for acrolein) and at 6.5 W and 7.5 W with A2 (up to 3.7 µg for formaldehyde, 0.8 µg for acetaldehyde and 1.3 µg for acrolein). The levels were increased by 30 to 250 times in dry puff conditions (up to 344.6 µg for formaldehyde, 206.3 µg for acetaldehyde and 210.4 µg for acrolein, P < 0.001), while acetone was detected only in dry puff conditions (up to 22.5 µg).

Conclusions
Electronic cigarettes produce high levels of aldehyde only in dry puff conditions, in which the liquid overheats, causing a strong unpleasant taste that e-cigarette users detect and avoid. Under normal vaping conditions aldehyde emissions are minimal, even in new-generation high-power e-cigarettes.

Conclusion

Aldehyde emissions in EC aerosol are associated directly with dry puff conditions. In normal vaping conditions, the levels of aldehydes emissions are minimal and by far lower than the levels in tobacco cigarette smoke, despite the use of high power levels. In dry puff conditions, aldehyde emissions are significantly elevated to very high levels, but vapers are not expected to be exposed to such levels during normal EC use, even when they use new-generation high-power devices.

a few little questions. I actually like dripping my 3 mg nic in max better even than vaping. I drip using 3 mg nic on a Istick 50 watt set about 23 watts with a draw of about 2.5 seconds and the coils reading says 1.6 ohms and the air holes blocked a tad on the el diablo bael. I vape on the Istick 20 watts somewhere around 7 to 8 watts on factory coil of 1.8 in a nautilaus mini
my questions: 1) does sub ohm in a rebuildable tank give flavour similar to a dripper
drippers seem to require higher watts is this in anyway suggested as less healthy ( I am not too concerned about the increased supposed formaldehyde issue I believe Dr F had issue with the research and in my opinion I probably breathe more formaldehyde off gassing wandering around carpets and insulation and pressboard)
2) the nic level is quite a bit lower in the dripper Does this actually translate to a drop in nicotine/contine levels in my blood in other words would I need to drip more to keep my nic levels somewhat reasonable re setting off " the I want a smoke brain run"
3 if I were to drip only for 3 or 4 days am I likely to find my 12 mg vape to strong

thanks for any insight you might provide  

I know this might piss some people off, but a fair study was done, and found that on high voltage tanks and MOD's produce high levels of formaldehyde

I change my coil infrequently,I notice sometimes when I rewick or change flavour on my rta,my coil looked black and gunk.After I rebuilt it and used it,the favour is ok and no dry hit, just a little less flavour.Recently,there is people contracting Vape related illnesses and a few died.I just don’t have too much time recoil and built,as usually rebuilding my rta which is relatively new released would take around 20min and I don’t have the time.Is dry hitting dangerous for the health because of Formaldehyde of dry hit or is the risk low?
What’s actually risky vaping nicotine,PG/VG only?  

I just came across this article, claiming that even nicotine-free e-liquids contain lung-harming substances like acrolein:

[URL='http://lungcancernewstoday.com/2015/06/08/nicotine-free-e-cigarette-vapor-also-damages-lung-cells/']Nicotine-Free E-Cigarette Vapor Also Damages Lung Cells Lung Cancer News Today[/URL]

What I hate about articles such as these is that they're almost always posted with some scary headline and usually end up saying there isn't a proper research into topic or they're awaiting further investigations.

Anyhow, can anyone comment on what 'acrolein' is? I've heard of formaldehyde being created when vaping on high wattage, but this is the first time I hear of acrolein.  

I'm a 45yo New Zealander, and I have absolutely no axe to grind, except one:

I smoked for 25 years. Therefore the tobacco companies have had more than their fair share of my money, and more importantly my health.

Thanks to vaping, using RBAs and mods, and diying my own ejuices - I've been smoke-free for 20 months.

One company that looks like winning, with all the fake news and hysteria being dredged up in USA over vaping is Phillip Morris International. And I'm not talking about their cigarette products - but rather their IQOS product.

A Device That Heats Tobacco, But Doesn't Burn It, Can Now Be Sold in the U.S. Here's What to Know About IQOS

The FDA have already approved this product for sale in USA. And how does the IQOS work?

the FDA says the pen-like IQOS device heats, but does not burn, “tobacco-filled sticks” wrapped in paper, creating an aerosol that contains nicotine. Marlboro, an Altria brand, will make the tobacco sticks used inside the cartridge, which will come in menthol and unflavored versions.

It's pretty much a cigarette, that goes into a device which 'heats' the tobacco, so you can inhale it.

Here's Why IQOS Could Completely Own the U.S. E-Cig Market | The Motley Fool

And how safe is it?

Comparison of Chemicals in Mainstream Smoke in Heat-not-burn Tobacco and Combustion Cigarettes. - PubMed - NCBI

There is little scientific data, however, of the hazards and toxicity of iQOS. In this study, we evaluated several harmful compounds (nicotine, tar, carbon monoxide (CO) and tobacco-specific nitrosamines (TSNAs)) in the mainstream smoke and fillers of iQOS, and compared their concentrations with those from conventional combustion cigarettes.

The concentrations of nicotine in tobacco fillers and the mainstream smoke of iQOS were almost the same as those of conventional combustion cigarettes, while the concentration of TSNAs was one fifth and CO was one hundredth of those of conventional combustion cigarettes. These toxic compounds are not completely removed from the mainstream smoke of iQOS, making it necessary to consider the health effects and regulation of iQOS.

iQOS may not be as harm-free as claimed, study finds

The University of California study found that, since the device could only be used for six-minutes before it needed to be recharged, it may cause some people to shorten the interval between puffs in order to make sure they did not waste any of the tobacco stick which could increase the possible toxic exposure.

But of greater concern was that the polymer filter melted slightly during use and released formaldehyde cyanohydrin, a toxic substance which could be fatal to humans. The compound is metabolised in the liver and broken down into formaldehyde and cyanide.

"This study has shown that the iQOS system may not be as harm-free as claimed and also emphasises the urgent need for further safety testing as the popularity and user base of this product is growing rapidly," the study concluded.

University of Otago public health and marketing Professor Janet Hoek said the findings led her to question whether it really was a "reduced harm" product as claimed by the manufacturers.

If users inhaled more frequently as it was suggested, it was likely they would "increase their nicotine intake and exposure to harmful compounds present in the inhaled aerosol", she said.

She said those who had tried unsuccessfully to quit smoking were better off considering e-cigarettes.

Just my

 

Any veteran vaper will tell you this truth.
We have all probably tried them at first. I know I did. I can tell you a universal and undeniable truth about them.
They are garbage.
They are nothing more than a most introductory lesson into vaping. I know of no vaper in my circle of friends that started with a cigalike and continue to use them. They have many flaws and 1 in particular comes to mind.
In the cartomizer, the unit that holds the 'liquid', no one has any idea what is in there. Sure, the package might tell you but how do you know? These cigalikes were the only product used in a study in 2008 to determine what was in the liquid. The results were disturbing but not surprising. They found formaldehyde, cyanide and other toxic chemicals usually found in cigarette smoke. So, yes, they really are cigalikes. But at the same time, painted the entire industry with a broad brush so now everyone thinks that vaping is just as deadly, if not more so, than smoking analog cigarettes which is nothing but one gigantic lie. Any vaper will tell you that.
Why were these chemicals found in a vaporizer? Because most cigalikes are, and have been, produced by Big Tobacco. They don't want to lose customers or money. They want every former smoker to be just as addicted to their cigalikes as they were to their cigarettes. There are several videos on YouTube of interviews with BT representatives that say this very thing.
Don't buy the garbage because it's cheap. Go to your local vape shop and talk to someone who was in your shoes.  

Looking at the charts, I would like to keep what I do in the green zone. What I cannot find is a chart that goes low enough in ohms to tell whether or not what I am doing is okay. My latest atomizer build is a .4 ohm on a Plume Veil. I use it with max airflow, side windows open full and top cap open allowing air. Excellent vapor production (for me anyway), at 7 watt - 1.7V (IPV2X mod reading). So where do you think that type of build would land in the charts. Safe to say I am in the green zone? I guess maybe I have developed some paranoia with this formaldehyde thing that has been floating around the internet. Does anyone know where to find a chart or calculator that goes from .1 ohm on up and indicating the safe areas?

Thanks,
Charles
