Is acrolein present in inhaled vapour from e-cigarettes?
When glycerine is overheated [1] and it decomposes (i.e. it is 'burnt'), acrolein is produced, which is a toxic chemical. This means that there is a genuine reason to examine the possibility that acrolein may be present in inhaled vapour from an e-cigarette, since almost all refills contain glycerine (aka glycerol, glycerin, VG).
How much nicotine is in vape juice?
You may have noticed that the vape juice bottles are advertised as 0mg, 6mg, 12mg, 18mg, 24mg, and 32mg. Nicotine in vape juice format is measured as milligrams per milliliter (mg/ml). That means that milliliter of vape juice will contain the set milligrams of nicotine.
Will acrolein be produced in a regular atomiser?
Acrolein will probably not be produced in any significant quantity in a regular atomiser until the smoke phase is reached, which is well past the point at which the vapour becomes impossible to inhale. We know this because of the multiple tests run by reliable investigators on regular ecig heads.
What are the diketones in vape juice?
The other two diketones are acetyl propionyl and acetoin. These aren’t as much of a concern as diacetyl, but many health-conscious vapers still try and avoid them in their vape juice. These ingredients served as alternatives to diacetyl after the whole popcorn lung incident revealed that diacetyl can be harmful when inhaled.
Does vape juice contain acrolein?
A number of studies have shown that in addition to nicotine and flavorings, e-cigarette vapors may also contain carbonyl compounds, including potentially harmful species such as formaldehyde, acetaldehyde, and acrolein [5,6,7,8,9] as well as diacetyl [10].
How much acrolein is in a vape?
Assuming an average volume of one breath of 0.5 L and our determined acrolein mass of 0.0032 µg/puff, we find an acrolein concentration in the lung of an e-cigarette vaper of 6.4 μg/m3, which is 16-fold higher than the above recommended WHO threshold.

Nicotine – a highly addictive substance that negatively affects adolescent brain development. Propylene glycol – a common additive in food; also used to make things like antifreeze, paint solvent, and artificial smoke in fog machines. Carcinogens- chemicals known to cause cancer, including acetaldehyde and formaldehyde.
Does Juul have acrolein?
Another chemical found in JUUL pods is acrolein. This dangerous chemical is a product of burning anything from wood, to tobacco, or even cooking oils. While mild exposure can cause general irritation, heavy exposure to acrolein, which happens when vaping, can severely injure a person's lungs.
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.
Is vaping worse than cigarettes?
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 cause popcorn lung?

Is VG safer than PG?
In certain cases, allergies due to PG have been reported. However, scientific studies show that VG and PG are harmless to human health. VG and PG proportion can severely affect throat hit, vape density, and flavor release. There is no magic number for VG and PG proportion.
Is acrolein a cigarette?
Acrolein in tobacco smoke Acrolein is not added to tobacco. Rather, it is produced during smoking by the burning of sugars present in the tobacco. Smokers inhale it when they take a puff of smoke (first-hand smoke). It is also inhaled in smaller amounts by passive smokers (second-hand smoke).
What does vaping do to your lungs?

An atomiser is a liquid-cooled heater element. In order for the atomiser coil to be hot enough to produce acrolein, there must be no liquid to cool it.
What happens if you don't add coolant to glycerine?
It may then become red hot; but if there is no liquid, then no acrolein can be produced. 2. Adding anything to glycerine reduces its boiling point.
Is glycerine good for vaping?
The term 'VG' is often used because in the past, vegetable-source glycerine was the best choice for vaping as the choice was between animal carcass source, biodiesel byproduct source, or vegetable source (palm oil or coconut oil). There was no easily-sourced synthetic glycerine. Why we don't inhale acrolein.
Is acrolein a toxic substance?
Explanation. When glycerine is overheated [1] and it decomposes (i.e. it is 'burnt'), acrolein is produced, which is a toxic chemical. This means that there is a genuine reason to examine the possibility that acrolein may be present in inhaled vapour from an e-cigarette, since almost all refills contain glycerine (aka glycerol, glycerin, VG).
Is acrolein produced by e-cigarettes?
No study declaring that acrolein was produced by a regular e-cigarette has ever been supported by independent investigators.

Can acrolein be inhaled?
Conclusion. Inhalation of acrolein is unlikely to be a problem with regular ecigs (minis and mid-size models). It is impossible to remove trace contaminants, but these are not seen as clinically significant here since they are universally present in all consumer products and impossible to remove completely.
Can you inhale acrolein in regular atomiser?
Acrolein will probably not be produced in any significant quantity in a regular atomiser until the smoke phase is reached, which is well past the point at which the vapour becomes impossible to inhale. We know this because of the multiple tests run by reliable investigators on regular ecig heads.

How Much Nicotine Is in a Bottle of E-Liquid?
Companies label their e-liquid with the amount of nicotine that’s in each milliliter of juice rather than simply providing the total amount of nicotine in the bottle.

What the Most Common Vape Nicotine Levels?
Vaping devices these days come in two primary classes. On one end of the spectrum, you have the small refillable pod systems that deliver potent bursts of nicotine in their small, wispy vapor clouds.

How Does the Nicotine in E-Liquid Compare to Cigarettes?

What Is Nicotine Salt E-Liquid?
Nicotine salt e-liquid is a form of vape juice that’s had its pH adjusted with an acidic additive such as benzoic acid.

What are the chemicals in diketones?
The chemicals known to be diketones are diacetyl, acetyl propionyl, and acetoin. Each of these are very different chemicals, and acetyl propionyl and acetoin can occasionally contain traces of diacetyl. Let’s explore these ingredients in more detail.
Is diketone a food additive?
Diketone is an additive used for buttery or creamy flavoring used in some food products as well as e-liquids. By law, the testing of diketones in food products is actually compulsory, however, it is not legally required to be tested in inhalation products. This is why many of you may have struggled to find information on e-liquids that are diketone free.
Is PG a safe vape?
SAFE: Propylene Glycol (PG) PG is non toxic and commonly used to carry flavor in food products, as an ingredient in food coloring and also used as an additive in various medicines. PG can be used in your vape on its own, but a blend that combines PG and VG is much smoother than a base that is 100% PG.

Media worldwide accordingly reported this new health hazard of e-cigarettes.
