How much formaldehyde do vapers really consume?
As Igor Burstyn did in his review, the authors of the new study compare their results with workplace limits, and conclude that vapers exceed recommendations for formaldehyde by over 200 times. This is in stark contrast with Burstyn’s conclusion that vapers only consume about 3 % of the limit per day.
What are the levels of formaldehyde in e-cigarettes?
Although there was quite a lot of variation between different devices, levels of formaldehyde on average were 0.189 µg per puff. 1 µg is 0.001 mg, or 0.000001 g. Many of the early studies with data on formaldehyde levels in e-cigarettes are summarized in Igor Burstyn’s review of the research on the chemistry of e-cig vapor.
Do flavoring flavors have formaldehyde?
Flavoring chemicals can themselves be aldehydes, so it isn’t as weird an idea as it may sound. Overall, the researchers found pretty high formaldehyde levels. The results for the Evod in particular are shocking, though.
Which e-liquids produce the most formaldehyde?
The results showed that only the PG-containing ones produced a lot of formaldehyde, with the PG/VG mix producing the most. The VG-based e-liquid barely gave off any formaldehyde.
How much formaldehyde is in a vape?
(2016) reported formaldehyde emissions of 48,200 μg/g liquid at 4.8 V using a similar atomizer. This means that the consumption of 3 g of liquid would be equivalent to smoking 1954 cigarettes in terms of formaldehyde exposure when compared to the tobacco cigarette smoke levels reported by Counts et al.
Can you get formaldehyde from vaping?
"Vaping" at high voltage also produced formaldehyde-containing compounds known as hemiacetals, the researchers found. Formaldehyde inhaled as a gas been associated with an increased risk of leukemia and nasopharyngeal cancer, which affects the upper part of the throat behind the nose.
How much formaldehyde is smoked?
In the main stream smoke of various kinds of cigarettes the amount of formaldehyde vary between 3.4 micrograms to 8.8 micrograms/cigarette, this is equal to concentration between 2.3 to 6.1 ppm.
How much formaldehyde is in a JUUL?
Regarding carbonyl compounds, JUUL aerosol contained low levels of formaldehyde (0.053 µg/puff), along with trace amounts of acrolein, acetaldehyde and diacetyl (Table 1).
How much formaldehyde is toxic?
The concentration of formaldehyde that is immediately dangerous to life and health is 100 ppm. Concentrations above 50 ppm can cause severe pulmonary reactions within minutes. These include pulmonary edema, pneumonia, and bronchial irritation which can result in death.
What vape juice is safest?
PG (Propylene Glycerin) – A liquid derived from propylene glycol. Though also considered safe by the FDA, it tends to have other applications, such as solvents and preservatives. Though both of these ingredients are deemed safe by the FDA, vegetable glycerin believed to be safer than propylene glycerin.
What happens if I smoke formaldehyde?
Adverse health effects Formaldehyde causes cancer in the nose and trachea and can possibly cause leukaemia. Inhaling formaldehyde from tobacco smoke can also cause irritation of the airways and damage to airway cells. Formaldehyde can also be irritating for the eyes.
What does formaldehyde do to the body?
When formaldehyde is present in the air at levels exceeding 0.1 ppm, some individuals may experience adverse effects such as watery eyes; burning sensations in the eyes, nose, and throat; coughing; wheezing; nausea; and skin irritation.
Is vaping safe?
1: Vaping is less harmful than smoking, but it's still not safe. E-cigarettes heat nicotine (extracted from tobacco), flavorings and other chemicals to create an aerosol that you inhale. Regular tobacco cigarettes contain 7,000 chemicals, many of which are toxic.
Does propylene glycol turn into formaldehyde?
Propylene glycol can become formaldehyde — a carcinogen — when heated to vaping temperatures.
Is embalming fluid in vape juice?
According to a 2016 report of the Surgeon General, vaping consists of a toxic aerosol containing cancer-causing substances. Vape juice also contains products such as formaldehyde, which is used in embalming fluid, and arsenic, a chemical found in rat poison.
Do Blu e cigs have formaldehyde?
Currently, according to the court documents, e-cigarettes are not highly regulated like tobacco cigarettes but there are toxic chemicals in the aerosol that users inhale, including formaldehyde. Independent testing verified the presence of formaldehyde specifically in the Blu products.
What is the name of the study that found formaldehyde in e-cigarette vapor?
The most infamous study on formaldehyde in e-cigarette vapor was published in the New England Journal of Medicine, under the title “ Hidden Formaldehyde in E-Cigarette Aerosols .”.
What is the chemical name for formaldehyde?
It's the simplest “aldehyde” chemical, with the formula CH (2)O.
What is dry puff?
Dry puffs play a central role in discussions of formaldehyde and e-cigarettes. This is where there isn’t enough liquid in the wick and the juice that is there gets “overcooked,” so to speak. This tastes horrible and is always avoided.
What is the dry puff in e-cigarettes?
The crucial factor in most discussions of formaldehyde in e-cigs is the “dry puff” phenomenon. As the name suggests, this is when there isn’t enough liquid in the wick but you try to vape. To understand this, we’ll first consider what happens during ordinary vaping.
Can you avoid formaldehyde in e-cigarettes?
How to Avoid Formaldehyde in E-Cigarettes. As we’ve stressed a few times, you can’t really avoid formaldehyde in e-cigarettes. There is always some, even outside of dry puff situations. However, the amount in these situations is generally low, and you’ll naturally avoid dry puffs anyway.
Is e-cigarette vapor a carcinogen?
The findings of the review didn’t support this conclusion. Firstly, what they mean by “carcinogens” is just formaldehyde, not the numerous other carcinogens found in cigarette smoke. Additionally, the evidence from the review shows that across brands, the average formaldehyde content was 0.42 µg per puff. Even the most formaldehyde-emitting brand still had 6 times less formaldehyde than found in cigarette smoke. The average amount detected was around 48 times lower than the levels in cigarette smoke.
Does dry puffing increase the quantity of formaldehyde?
Dry puffs increase the quantity dramatically, but under normal circumstances there is still formaldehyde. Chemically, some of the molecules always have enough energy to undergo the reaction. Increasing the temperature just increases the average energy of the molecules and thereby makes the reaction happen more often.
Is second hand vapour toxic?
The false claims saying that secondhand vapour contains toxic levels of formaldehyde, started as a result of a paper published in January 2015, in the New England Journal of Medicine (NEJM).
Is there air sampling in vape shops?
In line with the above, in 2017 the California Department of Public Health (CDPH), had also been carrying out air sampling in vape shops throughout the state. In his blog, Public Health Expert Dr. Michael Siegel had shared the results obtained from a relatively small and non-ventilated vape shop, where many of the employees and 13 customers were actively vaping while the sampling was taking place, hence what would be considered a situation presenting a high level of exposure to second-hand vapor.
Why was the 2017 Portland study flawed?
The Portland team argued that the 2017 reinvestigation of their work was flawed because it ignored the new formaldehyde compounds discovered in the 2015 paper. Instead, the authors of the replication study simply stated that the more common “gaseous” form of formaldehyde would not affect e-cigarette users at intermediate heats.
Is vaping toxic?
The toxicity of vaping is once again being debated. Three years ago, researchers at Portland State University in Oregon conducted a study that found previously unknown forms of formaldehyde in the vapor of electronic cigarettes (e-cigarettes).
Formal-de-what?
Formaldehyde is a naturally occurring organic compound: a colourless, pungent-smelling gaseous substance. It can be used for a range of purposes, including in manufacturing building materials like plywood, as an ingredient in glue and as a steriliser.
Run, Hide, It's Formaldehyde!
The National Toxicology Program in the U.S. classified in the "11 th Report on Carcinogens" that formaldehyde is “reasonably anticipated to be a human carcinogen”. Carcinogens are substances capable of causing cancer in living tissue - so yep, formaldehyde is sufficiently scary stuff.
E-Liquid: X-Rated?
So we’ve established that formaldehyde is something best avoided. But how does this relate to vaping liquid?
Blowing Off Steam
Since the publication of this report, multiple researchers have called for its retraction. Dr. Farsalinos, a cardiologist who has performed research on electronic cigarettes since 2011, also published a paper disputing these claims, stating there were “many major issues in that study.”
None the Wiser
As with many debates surrounding the contents of e-juice, it always comes down to the fact that long-term research into the effects of vaping is limited. Whether you’re for or against vaping, it’s still a relatively new invention and, as such, we can dispute and discuss all we like: we’re still none the wiser.

Ok I looked it up, and I don't understand what they mean. Its kind of long so bear with me.

If you want to minimize Formaldehyde and Acetaldehyde formation, the key to Limit the Temperature the Coil can reach. So Reducing the Amount of Airflow is going to be Bass Ackwards.
VapinNationStation Full Member
Agreed. To cut airflow from full to anything less, the coils and juice would actually get so hot you probably could not even put it near your lips without fear of burning. Plus have the coil burn out in a few puffs.

I cant use tc because its kanthal. But I get what you're saying. Ive done the conversion for 100w its only about 3.4volts for 2 batteries so I should be fine then. Thanks!
Mordacai Vaping Master ECF Veteran
VapinNationStation, there's a Japanese study where they tested more than one type of device. As a lot of studies concentrated on c4e type and they artificially chain vaped them at unrealistic levels, quite probably drying the coil out and burning it somewhat in the process.

One of the Biggest things a Non-TC Vaper can do to reduce the potential of Formaldehyde and Acetaldehyde formation is to Not Do Back-2-Back Hits.
bombastinator ECF Guru Verified Member ECF Veteran
I don't think its very hot, because its 100w going into basically 4 coils, so probobly 25w each coil in the 1 coil now that i think about it. I usually don't take more than 1-2 puff then put it down for a couple mins, and the puffs only last about 1-2 seconds.
