New 'baddie'. Mint/ Menthol Flavor Causes Cancer.

Hi,

I just read reports that pulegone, which is found in peppermint oil and is a carcinogen, are found in "minty" e-cigs.
Vape Pods Taste Minty Thanks to Extremely High Levels of a Chemical Banned in Food

High levels of cancer-causing chemical found in mint and menthol e-cigarettes: Study

This causes concern as I've been mixing my own juice using menthol crystals and PG, VG. I wonder if pulegone is found in menthol crystals too. As I understand, menthol crystal is derived from peppermint, just like pulegone, but that doesn't mean menthol has pulegone does it? It seems menthol has its own molecular structure.

Thanks  

I smoked menthol cigarettes for 45+ years. Never cared for the taste or smell of cigarette tobacco, but I liked my menthol. When I tried Blu ecigs, the tobacco didn't taste like tobacco, it just tasted "meh". The menthol flavor was more meh with a mentholesque hint, and they were a freaking hassle. When I finally realized this weird vaporizer shop across the street from the hospital and next to the ambulance company actually sold E-cigarettes, not those things you steam up a room with Vick's Vapo-Rub, I went in and told them about my experience with Blu's and asked if they had anything better. I walked out with an eGo starter kit, some fruit flavors, and some menthol and mint juice to mix with them. Success! Got my menthol/nicotine fix and was able to put down the combustibles! For a year and a half I've been doing the same thing only DYI: Fruit and menthol and/or mint. Just had to have that menthol feel or it didn't do the trick for me.

Last week I got a bunch of new flavors from MFS. I mixed up some desert coffee and a key lime pie concoction, no menthol or mint, and it was GOOD!

Now if only somebody would tell this stupid spell checker there is no "u" in flavor!  

Does anyone know if mint and menthol are considered flavors, for the purpose of the upcoming ban. I always thought they weren't but on the radio today, I thought I heard it say that they will be banned too.  

Are there any pods or AIO that handle high levels of PG (50 to 100%)? And any suggestions of what to do with the Suorin Air I can't use?

I literally just got my order, a Suorin Air and after opening the box, the insert lets me know its useless to me. I didn't remember to factor in types of ejuice when I was researching vape pods. Apparently it won't do well with anything less than 60VG/40PG and my lungs can't handle that ratio. The most I can do is a 50/50 blend but since I've been making my own its easier to just do pure PG. Especially since all I make is menthol using crystals.

 

The Canadian federal government published guidance for the federal flavor ban in their latest Canada Gazette Part I (https://gazette.gc.ca/rp-pr/p1/2021/2021-06-19/html/reg2-eng.html)

The federal government is proposing a prohibition on all flavors other than Tobacco, Mint and Menthol.

They define "flavor" as anything that has a sensory attribute in inducing youth to vape - this means that if it smells like strawberries, it's banned. If it smells like cream, it's banned. If it smells like anything other than tobacco, mint or menthol, it is prohibited for sale in all of Canada.

There is still time to act.

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.

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

Vaping is supposed to be a form of harm reduction, that is, allow nicotine addicts to have access to the drug without the harmful tars and chemicals in cigarettes that cause cancer, heart disease, and other maladies.

Last year, the Journal of the American Heart Association published a study finding that vaping posed as great a heart risk as smoking itself. That study fueled public policies at all levels of government to stifle the industry. A lot of small business people had their livelihoods destroyed or damaged as a result.

Now, the study has been retracted — which is a very big deal in science — because the editors are “concerned that the study conclusion is unreliable” due to what appears to have been an uncompleted peer review process..........."

Major Anti-Vaping Scientific Study Retracted | National Review


Score one for our side. 'They will not stop until tobacco becomes regulated like a hard drug - 'We will not stop until our rights, especially our right to use a less harmful form of tobacco, such as vaping,
is assured.  

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

 

Hey Guys,

I recently bought a new ecig (Joyetech eroll-c) and got a bottle of menthol liquid with it which I loved and the ecig performance was spectacular!
Traditionally I had used a Halo G6 and there liquids.

Now I've run out of poor menthol and going back to Halo liquids I've noticed that they instantly give me a headache even smoking a light 6mg nicotine bottle of Tribeca!

Could it be the blend and does anyone have these headaches with Halo or another brand?
