E-cigarette liquids contain flavorings and fragrances, which are generally recognized as safe for consumption and are found in food products.

One of the recurring headlines in the media in recent years talks about diacetyl, which appears in some liquids as a flavor additive.

This chemical has previously caused serious illness in several workers at a popcorn factory who were exposed to huge amounts of fumes from this substance.

Therefore, in the vernacular, the disease began to be called "popcorn lung."

So what exactly is diacetyl?

Diacetyl is an organic compound that occurs naturally in fermented products such as alcoholic beverages and various dairy products. It is also found in certain fruits and tobacco.

Diacetyl is widely used in the food industry because of its buttery taste and its ability to accentuate sweet flavors.

It was used as a buttery flavoring additive in the popcorn industry until the "popcorn lung" incident. Since then, most manufacturers have avoided using this substance.

Is there diacetyl in electronic cigarettes?

Diacetyl may be found in e-cigarette liquids.

After the publication of Dr. Konstantinos Praslinos' study in 2014, which showed that some liquids contain trace amounts of diacetyl, the industry underwent many changes.

Many companies today make a point of producing liquids without using diacetyl.

Can an e-cigarette cause popcorn lung?

Despite incorrect and false reports in many media channels making this claim, such a case has never been documented.

A regular tobacco cigarette contains diacetyl at a higher level than any electronic cigarette device, at least a hundred times higher.

There are about a billion smokers in the world. Although smoking causes other serious lung diseases, no case of "popcorn lung" has been documented in tobacco smokers.

In the "popcorn lung" cases that occurred at the popcorn factory in question, exposure to diacetyl was at unusually high levels, such exposure is impossible when using an electronic cigarette.

Therefore, it was determined that an e-cigarette cannot cause "popcorn lung" and that this disease was only caused by people who were exposed to huge amounts of this substance.

It is important to note that although diacetyl in the tiny amounts it was found in e-cigarette liquids cannot cause disease, most serious and high-quality companies still avoid using it and even state this on their website or on the bottle.

This is in order to provide their customers with the safest and most enjoyable experience possible.
