Diacetyl has been found in numerous different e-cigarette liquids. Popcorn lung is an irreversible condition and although the electronic cigarette industry is largely aware of this challenge, it cannot be verified whether or not every different manufacturer of e-cigarette liquid has taken the appropriate precautions to remove it from their products.
Popcorn lung has never been diagnosed in smokers â or at least not because of smoking. People who work in the factories and inhale it directly are the only ones diagnosed with it. That means diacetyl present in cigarettes does not cause popcorn lung, right? May be, but we are not completely certain about it as more research is required.
