Can Vaping MCT Oil Give You Lipoid Pneumonia?

Can Vaping MCT Oil give you lipoid pneumonia? Lipoid pneumonia is a condition that occurs when lipids – the medical term for fats – enter the respiratory …


  1. Finally, the last article (Medium-chain triglycerides: An update) does not speak specifically about the consumption of MCTs via inhalation, so isn't really a relevant source at all.

    I'm not meaning to rain on anyone's parade, but the sources outlined in this video did not raise my confidence in the safety of vaping MCT-based e-liquids, and that is disappointing because I came across this video looking for sources to support their safety. I suppose that this is also a lesson that just because something is supported by scientific sources doesn't mean that those sources were necessarily interpreted correctly and that doing your own research is important.

  2. One of the other articles (Respiratory infections and pneumonia:
    Potential benefits of switching from smoking to vaping) also does not mention MCT oil, it simply says that "The assertion that vaping could put people at
    risk of lipoid pneumonia is illogical, simply because commercially available e-liquids (those with a base of propylene glycol or vegetable glycerin) do not contain nor generate fatlike material." This is not the case for MCT-based e-liquids.

  3. Based on one of the articles shared in the video, (Lipoid Pneumonia: Spectrum
    of Clinical and Radiologic Manifestations) the lipids that cause the most severe cases of chronic (due to prolonged exposure) lipoid pneumonia are animal fats BECAUSE they are completely hydrolyzed in the lungs. If MCT coconut oil is also completely hydrolyzed, wouldn't this mean it poses a significant risk? Also, that specific article was outlined in the video as a source supporting the statement that "MCT oil cannot be linked to lipoid pneumonia," but the article does not mention MCT oil or MCTs at all.

  4. "The jury is still out on the long terms effects of vaping MCT. A study conducted by the Medical Marijuana Research Institute found that MCT only "produced negligible levels of harmful byproducts" when heated to 230°C. However, another 2017 study in the Journal of Alternative and Complementary Medicine found that while MCT did produce less acetaldehyde than other thinning agents, it still produced heightened levels of one or more potentially harmful cancer-causing particles. So, while questionable, MCT may not pose as much of a risk of other thinning agents that we’ll delve into more down below."
