Good lord, so the whole vaping and "popcorn lung" thing is making its way around facebook, yet again. I've been sent this article by no less than 10 people in the last 24 hours. Let me break it down for you. Let's share this instead.
Popcorn lung is a very serious lung disease with multiple causes, one being from a chemical known as Diacetyl.
Diacetyl is the chemical component that causes popcorn lung, yes. It is an artificial butter flavor. Yes, there is Diacetyl in a ton of e-liquid. So yes, e-liquid contains a chemical that causes popcorn lung. However...
There have only been 6 cases of popcorn lung in the history of the planet. All six people worked full time at a popcorn manufacturing plant. They worked 8 hour days 5 days a week for 15 years before they inhaled enough micrograms of Diacetyl to develop popcorn lung.
About a year ago 99% of e-liquid on the market was tested for Diacetyl. The most potent juice, having the most Diacetyl, was, lets just call them 'Brand X'. Even though 'Brand X' had a relatively high Diacetyl content in comparison to the rest of the market, here is the fun part... you would have to vape 60mls, aka 2oz, aka a TON (almost impossible amount, the average is 2-20ml a day) of their liquid, EVERY DAY for 1.5 MILLION YEARS, in order to accumulate the amount of micrograms of Diacetyl it takes to develop popcorn lung. It is literally impossible.
A simple cigarette, one single cigarette contains 750xs the amount of Diacetyl that there is in a full bottle of 'Brand X', and no one has ever gotten popcorn lung from cigarettes.
National average smoker, 1 pack a day, 20 cigarettes.
750 x 20 = 15,000
If a full bottle last three days... 15,000 x 3
Based on averages, smoking cigarettes contain 45,000xs more Diacetyl than vaping.
So yeah, vaping can cause popcorn lung.
You'd just had to vape every second of every day for 1.5 MILLION years. Numbers simply do not lie.
Now please, stop sharing it.
