" I have seen many articles saying vaping can cause popcorn lung. Does anyone have info on this? Thank you! xx Claire"
Popcorn lung can be caused by vaping a substance called diacetyl, used in flavoring e-cigarettes/vapes. There is no reason for there to be diacetyl in a medical cannabis vaping preparation. In fact, most preparations are now also solvent-free to further reduce the risk of inhaling substances that could be harmful. In general, I’d say the minimal amount of vaping involved in cannabis use compared to the amount in habitual vaping of nicotine containing formulas makes it extremely unlikely as a health risk unless you have some kind of known respiratory condition.
