There seems to be a lot of misinformation about vaping essential “oils.” I am no scientist, but have done some research.
Essential “oils” are given the name oil because they are not easily soluble in water. They have no relation to oils like animal fat or vegetable oil (those are the ones that contain lipids). Almost all essential oils are free from lipids because of how they are made.
If an essential oil is “distilled”, which most are, you can be almost sure it doesn’t have lipids. You distill an essential oil by boiling the fruit/flowers/plant and collecting the steam. Lipids do no boil until around 250c, and the distillation process happens at 100c normally. All lipids are left behind! If the essential oil is expressed or made with a solvent, you can’t be so sure. Tobacco absolute is a solvent extracted essential oil, but should be free of lipids. Citrus essential oils are usually cold pressed, but are lipid free. Others I am not sure of.
But even then, has anyone looked into how people get lipid pneumonia, and how rare it is? And how much oil they actually aspirated? The cases I see are mostly from people that ingest large amount of oil for health reasons (relieving constipation, etc.) and they either aspirate some of it, or it comes up as acid reflux and then is aspirated. We are talking many milliliters of oil aspirated over many years. Mostly elderly people and infants, with a few cases of fire-breathers. The amount of “oil” a vaper would inhale is LOW. Like 0.02ml of essential oil per day if they are a heavy vaper using nothing but eliquid made from essential oil flavor.
Also, how do you guys think that TFA, Capella, FW, FlavourArt, and others are making your (natural) flavors? If you have any (natural) fruit, mint, floral, citrus, or other plant derived flavors, they are made from diluted essential oils. For example, look at clove flavor from TFA. They clearly say that it is 20% Eugenol. Eugenol is essential clove oil. TFA Clove flavor = essential oil. This is true for many natural flavors.
Also, the main use for essential oils is inhalation (aroma therapy). Essential oils are so volatile (tiny molecules) that they evaporate easily at room temperature. Then you breath them. People have been inhaling essential oil for many years before ecigs hit the market. They even put essential oils in CPAP machines for people with breathing problems.
Don’t be so quick to dismiss a flavor because it says “oil” on the bottle. Do some research and make an informed decision.
DISCLAIMER: I am no expert. I am sure there are some essential oils that could be harmful if inhaled, especially if it is in concentrated amounts. I just want to make the point that not all “oils” are created equally, and you should not dismiss a flavor just because of this word. Also, pure essential oils are very strong and should be diluted much more than your manufactured flavors. Sometimes even 1 drop per 10ml is too much, so you may need to pre-dilute them before use. ---- SumDudeYouKnow
