Can standard CBD oil be vaped if a person happens to run out of CBD vape oil? After all, sometimes you run out of things and it helps to have a backup plan in case you can't get resupplied quickly. The problem is that CBD oils in the form of tinctures are actually mixed with a base oil - many times tinctures use MCT Oil, which can be healthy to ingest and increase bioavailability of a tincture in your digestive system -- but should not be inhaled into your lungs. If you have pure CBD distillate at home (which is rare), you can vape it, but it may actually be easier to dab. Generally, you really should never try to DIY a vape as it could be bad for your health - it's your lungs after all, so leave it to the experts. Bottom line - If you run out of CBD vapes, don't fill a cartridge with your tincture and vape it. Read on to learn the science behind why.
