Study Shows Dr. Oz Warning Correct About Vaping Habit Poisoning Smokers

Tested e-cigarettes contain harmful additive

Are you one of the many smokers who view vaping as a healthy alternative to cigarette smoking? If so, then you may want to know about the risk of “Popcorn Lung” disease from your vaping habit.


Last year, Dr. Oz warned viewers about the possible health consequences of taking up a vaping habit in lieu of cigarette smoking. Vaping is the act of using a smokeless nicotine delivery device that is filled with liquid nicotine adulterated with chemical flavorings that make the vaping experience more pleasurable and without the smoke inhalation complications of cigarettes. Currently there are more than 7,000 varieties of flavored e-cigarettes and e-juice (nicotine-containing liquid that is used in refillable devices) on the market that includes “fun” flavors such as raspberry, key lime, peaches and cream—and even cotton candy and gummy bears!

“But the fun flavors should not hide the risk,” says Dr. Oz. “Along with the nicotine, E-juice may have additives and contaminants that could be carcinogenic.”

As it turns out, Dr. Oz’s warning about the additives in E-juice appear now to be not far off the mark as reports of a recent study reveal that the majority of a sampling of 51 types of flavored e-cigarettes sold by leading e-cigarette brands and flavors that are appealing to young vapers contain a chemical flavoring additive called “diacetyl” that is known to cause Popcorn Lung disease in workers exposed to the chemical.

Popcorn Lung disease is technically known as bronchiolitis obliterans—an irreversible medical condition where scarring occurs in the tiny air sacs in the lungs where oxygen is passed on to the bloodstream. In 2004, the CDC reported several cases of bronchiolitis obliterans in workers in a microwave popcorn plant in Missouri that was attributed to the diacetyl flavoring chemical used to give popcorn its buttery taste. People affected by the chemical spend the rest of their lives with constant coughing and shortness of breath.

“Recognition of the hazards associated with inhaling flavoring chemicals started with ‘popcorn lung’ over a decade ago. However, diacetyl and other related flavoring chemicals are used in many other flavors beyond butter-flavored popcorn, including fruit flavors, alcohol flavors, and, we learned in our study, candy-flavored e-cigarettes,” said lead author Joseph Allen, assistant professor of exposure assessment sciences.

In the study, Dr. Allen and colleagues tested 51 types of flavored e-cigarettes and liquids with a special device that mimics the act of vaping via an e-cigarette inside a sealed chamber that draws air through the e-cigarette for eight seconds at a time with a resting period of 15 or 30 second between each draw. The air stream (vapors from the e-cigarette) was then analyzed.

What they found was that in 39 of the 51 flavors tested, diacetyl was detected in amounts that were above the laboratory limit of detection. Other potentially risky chemicals were also detected in the majority of the e-cigarettes tested.

The researchers concluded that, “Due to the associations between diacetyl, bronchiolitis obliterans and other severe respiratory diseases observed in workers, urgent action is recommended to further evaluate this potentially widespread exposure via flavored e-cigarettes.”

“Since most of the health concerns about e-cigarettes have focused on nicotine, there is still much we do not know about e-cigarettes. In addition to containing varying levels of the addictive substance nicotine, they also contain other cancer-causing chemicals, such as formaldehyde, and as our study shows, flavoring chemicals that can cause lung damage,” stated study co-author David Christiani, Elkan Blout Professor of Environmental Genetics.

Yes and what is new here... Diacetyl was already found in some Liquids in 2014, also this study shows that the levels are extremly low.. Also much lower compared to some brands of Microwave Popcorn, roasted coffee and first of all regular cigarettes. Also Diacetyl is only linked to the "Popcorn"-Lung, so there is a low potential risk if inhaling a lot of diacetyl (several time more than found in this study). Why.. There is only one larger case known in a Popcorn Factory, why is this a potential low risk? Diacetyl is created also in high amount during the process of roast coffee and it will be inhaled thru workers that "roast" coffee. But in this area the "Popcorn"-Lung is not seen or has been reported. So i can't see any problem here....
DrOz, is not correct. This article is propaganda. It makes no mention of the fact that cigarette smoke already contains much more diacetyl and yet popcorn lung is not common in smokers. Or that no vapor user has been diagnosed with this illness related to vaping buttery flavors. People have been vaping for many years now, myself close to 10. I'm sure some day we will find some factual harm but this is just sensationalist propaganda.
I have been vaping since April and the past 3 months now, I have felt very over exerted. I walk 2 blocks and feel like I ran a mile. I am short of breathe and am weezing. I went to dr. They put me on loratidine and didnt help at all. Then she put me on a Z pack and prednisone and thats not helping. I am really hoping its not pop corn lung from vaping. Does anybody else have any issues like this?
It isn't the vaping causing that problem. I have vaped for over 5 months now and nothing like that has happened to me. Of course, you want to try and avoid diacetyl and other chemicals in your juices, and the best way to do that is to look into the companies that manufacture these juices. The chemicals may not be as sensationally harmful as this article makes them out to be, but what's the problem with just avoiding them altogether? As for your hard breathing and exhaustion, it is for sure not from vaping. I would ask your doctor about it, *but*, DO NOT mention that diacetyl thing to them. Sure, you vape, but any person who views vaping in a negative light is going to jump to that conclusion, and I as well as thousands of others who vape HAVE NOT, gotten popcorn lung from this, or shortness of breath, even after an extendes period of time.
Vaping made me feel like my lungs were going to collapse xxx avoid vaping like the plague .
