One of the main benefits of vaping CBD/THC is that it is an incredibly efficient way to consume cannabinoids. Bioavailability refers to the proportion of a substance consumed that enters your bloodstream, essentially the amount you are receiving. Any medication administered intravenously has 100% bioavailability, for example.  Studies tell us that vaping can deliver an impressive bioavailability of 70%. 70% bioavailability is far higher than smoking, typically around 30% and only 6-20% if orally consumed. 
Vaping is an effective way to feel the results fast.
