Diacetyl is a chemical that occurs in low concentration in coffee, honey, apples, vinegar, and tobacco. It is used by manufacturers to add a buttery taste to products like oil sprays, snack food, margarine and lately e-juices. Heated diacetyl may cause coughing and lead to respiratory sickness. Thus diacetyl-free e-juice flavoring is in high demand among savvy vapers – and for a good reason. E-liquid companies are aware of this and for the most part, have made conscious efforts in reducing or eliminating this chemical. Some manufacturers took this step and started producing superior, safe e-juices that deserve top charts positions.

Unlike most tobacco-flavored vape juices, Black Note’s diacetyl free vape juices use real flavoring derived from real tobacco. Jazz is one of Black Note’s many takes on tobacco-flavored vape juice.
This one is derived from an American blend of tobacco. Because Black Note’s vape juices are all-natural, their flavor is more subtle. That being said, Black Note’s all-natural, diacetyl free vape juices taste far closer to the real thing.

According to the Centers for Disease Control (CDC), diacetyl is best known for its use in popcorn flavorings (but has since found itself in many e-liquids). It was eventually associated with lung damage, resulting in decreased respiratory function. Animal studies by the CDC also showed severe lung impact following diacetyl exposure. Frequent vapers greatly significantly reduce potential respiratory harm by avoiding this substance.
Diacetyl is safe to ingest, but the research shows it is hazardous when inhaled. This chemical is not a necessary component in e-liquids, so always research the product in order to prevent potential lung damage.

The lab test results from several e-juices shows that diacetyl has been found in varying degrees, depending on the flavor.
The letters “ND” stand for “non-detect,” implying that the amounts were too insignificant for the equipment to find any diacetyl. This legend is universally used in third-party lab analyses, making the results simple to read and allowing consumers to identify diacetyl-free e-liquid easily.
Lab tests published by Harvard University in June 2016 found that diacetyl was most prominent in tobacco and menthol flavored e-liquids; however, the e-cigarette industry has evolved considerably year over year. While menthol and tobacco are likely culprits for diacetyl, they do not universally contain it.
Quick Facts About Diacetyl
Although used in artificial flavorings, diacetyl is created naturally through yeast fermentation.
In addition to buttery flavors, diacetyl is used in some Chardonnay wines and a wide variety of fruit flavors consumed on a daily basis.
Diacetyl gained infamy when it was linked to a condition called bronchiolitis obliterans – colloquially referred to as “popcorn lung” due to the harmful effects of its inhalation popcorn factories that lacked ventilation.
Diacetyl in Vape Juice vs CigarettesIs Diacetyl Negatively Affecting Vapers?
While diacetyl exposure in cigarette users is far greater than that in vapers, the chemical should still be avoided when possible. Small amounts of diacetyl are still potentially harmful, and diacetyl free vape juices are potentially less harmful than those that include diacetyl.
A report from the Department of Environmental Medicine and the University of Rochester Medical Center in Rochester, New York affirms the idea that diacetyl free e juice is less harmful than vape juices with diacetyl.
This report assesses the risk of diacetyl to vapers and concludes that vape juice without diacetyl is potentially less harmful.
The report concluded that exposure to diacetyl when vaping caused a significant biological inflammatory response. According to the same report, diacetyl in vape juice could potentially be toxic to the lungs and could potentially cause damage to the user’s bodily tissue.
Diacetyl is potentially harmful to the lungs, and avoiding it is a sensible precaution that a lot of vapers are taking. Luckily, there are a lot of vape brands that make diacetyl free vape juice for vapers that don’t want to take the risk.
Fortunately, there are thousands of brands and flavors available that not only avoid diacetyl but also use very high quality, reputable ingredients. The aura of transparency and responsibility in the e-liquid market is truly notable, so vapers everywhere should support and promote diacetyl-free e-liquid brands.
Diacetyl – like many substances – is both benign and dangerous. Although safely used for years as a food flavoring, it is clear that the substance is unsafe for inhalation.
