Does Vape Juice cause popcorn lung?

[sg_popup id=”2″ event=”onload”][/sg_popup]

If you read nothing else, read this:  No known cases of “popcorn lung” or Bronchiolitis Obliterans have been attributed to vaping.

Since vapor companies are now regulated as tobacco products, we are compelled by law not to make any health claims including smoking cessation claims. Unfortunately anti-vaping groups and unscrupulous journalists are not bound by the same regulations and restrictions on health claims, even when they’re exaggerated, unfounded, or completely made up.

We can, however, provide you basic facts to make your own informed decisions as a consumer.

What is “Popcorn Lung”?

In August 2000, the National Institute for Occupational Safety and Health (NIOSH) began investigating a string of 8 popcorn factory workers who had developed Bronchiolitis Obliterans, a respiratory disorder with a number of possible causes.  The disorder was thus given the nickname “Popcorn Lung”.

NIOSH and the Center for Disease Control (CDC) found no known airborne respiratory toxins in the factory, and began to look for chemicals that may not have been previously known to cause the disorder.  In their air sample tests they found 18 parts per million (ppm) of Diacetyl in the mixing area, 1.3 ppm in the microwave packaging area, and 0.02 ppm in other areas of the factory.  Four of the eight subjects worked in the mixing room, four worked in the packaging area.  No cases had come from any other areas of the factory.  NIOSH concluded that Diacetyl was the likely cause and established strict workplace airborne exposure limits of 25 parts per billion (ppb) for short term exposure (15 minutes) and a time weighted average of 5 ppb for long term exposure (40 hour work week). Note that this falls significantly below the levels of 20 ppb found in areas of the plant where workers were unaffected.

Where does Diacetyl come from?

In the case of the popcorn factories, Diacetyl was being used as a butter flavoring. However, it Diacetyl does occur naturally, such as a byproduct of fermentation.  It is commonly found in butter, buttermilk, sour cream, as well as alcoholic beverages.  Most importantly it is also found in cigarette smoke.

The poison is in the dosage

I’d like to pause for a moment to point out this very important, but often overlooked detail. Journalists’ jobs are not to inform you. Their job is to get you to view the article on their website or in their printed newspaper, so that their employer can bring in advertising revenue. Nothing works better than shocking and scary headlines that grab your attention, like “Toxic chemicals found in so-and-so-product!”.

The first problem with this is that they turn “chemicals” into this big scary word. Everything is a chemical. Even water, the great giver of all life as we know it, is a chemical.

The second problem with this is that every chemical is toxic at the right dosage. Including water, the great giver of life. Go ahead, google “water poisoning”. I’ll give you a quick quote from wikipedia to save you the time: “Water, just like any other substance, can be considered a poison when over-consumed in a specific period of time.”

So the key here is that the poison is in the dosage. Arsenic, a chemical well known for its toxicity, has a good chance of being found in your drinking water. The key is keeping it at safe levels.

Is there diacetyl in eliquid?

Contrary to anti-vaping groups’ attempts to depict the vapor industry as a big bad wolf and tobacco industry 2.0, the Diacetyl issue was brought to light by the vapor industry itself.  There was talk of avoiding butter flavorings back in 2009 when the industry was nothing more than hobbyist vendors talking on online forums. It was Dr. Konstantinos Farsalinos, a greek cardioliogist, vaper, and vapor industry proponent who in 2014 brought this issue to the forefront. He tested a number of eliquid samples, with willing participation of the companies producing them, and found Diacetyl present in the liquids.

Dr. Farsalinos pointed out in his research that most of the liquids contained Diacetyl below the NIOSH safety limits of exposure. However even the worst offenders would expose the user to 100 times less Diacetyl that cigarette smoke, which itself has caused no known cases of popcorn lung. His opinion was that regardless of the relative level of risk, this was an avoidable risk. He suggested that the industry work with the flavoring industry to adapt flavorings for use in vape juice by eliminating Diacetyl.

Guess what happened? The industry got to work doing precisely that.  All the flavor houses that supply eliquid manufacturers spent the next two years creating new flavorings without Diacetyl.

Unfortunately “Vapor industry identifies possible but unproven health risk and works to fix it on its own” made for a bad headline, and these old news articles continue to get reposted to facebook and social media.

  1. I have never heard of anyone getting popcorn lung from any form of e-juice. I have been vaping for over 2 years

  2. This written article is chock full of truths. I appreciate the insight as anti-vapors continuously bring up this subject. Heck, even vaping-friends have tried stating such allegations (while still vaping). Information should be passed only after completely understanding where and how it came to fruition. Thank you guys and gals for having your very own vaping community in mind, not just profits. Keep up the excellent job at informing!

  3. This is how i feel about the whole thing (however meaningless and small my ONE opinion may be).
    I feel that the large majority (albeit not EVERYONE) of people who vape do so after smoking cessation. This being said, statistics will show you that 1 of every 3 people has tried illegal drugs and we’ll say at least 20% of Americans use inhaled drugs (this being anything from marijuana to meth and all in between) on a regular to semi-regular basis. I said all that to say that of all the “chemicals” that humans willingly and sometimes unknowing inhale….it would honestly seem that anything in an eliquid would really be much better than the alternatives of analog cigarettes or illegal drugs. So while people are wasting time preaching about the dangers of vaping, I’m just gonna sit back and vape my yummy creamy diacetyl, thrive in my success at quitting smoking, enjoy my teeth being whiter and my clothes not smelling like an ashtray!! Good read, thanks for posting and as always….VAPE ON!

  4. Lmao agreed!!!!! Puff On , I’m gonna sit back and see how long it takes someone to read ur comment and make a meth base / flavored e-juice , oh my lawd , as on the other hand ,you tellin the truth, I think our juice is probably the safest thing we do, unless you purchase it in some dark non GPSable location! Have a great day

  5. AMEN to that!!! I just posted a quite long, we will call it for lack of better words a educational piece on Facebook. Then I posted the article that we have all just read about popcorn lungs. Hopefully if we all speak up the ignorance will stop! I urge you all to share the article provided to us.
    Let’s get our words and thoughts heard.
    Thanks again Ash! You have inspired me more! Heres vaping to you…!!! ☺

  6. All I can say to my fellow vapors, is vape-on! Don’t stop putting your words out there! We need to be heard.
    Amen to those of you with the courage to take a stand and for doing your research! Keep it up!!!

  7. I just had this argument with my mother yesterday (she’s against me vaping). And I explained it to her this way – that I’ve heard somewhere (I believe it was one those anti-smoking ads, so take that for what it’s worth) that there are something like 1100 other chemicals added to regular cigarettes and in the most simplistic formula, there are 4 or 5 ingredients in a vape fluid so I’d rather take my chances with vaping.

    Thank you for this article! I will certainly be forwarding it!
