@C No Ego To simplify - both black pepper (because it has beta-caryophyllene) and Cannabidiol (CBD) keep THC from binding to CB1 and CB2 receptors. The effect is that THC can't bind at those receptors and so the user doesn't get as high, or can come down somewhat if they feel paranoid or too spaced out from the THC. When you say that pepper and CBD slow down degradation of THC it seems like you are trying to say that the THC high would subsequently last longer. And black pepper can "substitute/supplement cannabis for micro dosing." I thought it was eating Mangos 45 minutes before vaping that accomplished that (because it has Myrcene). And my experience is exactly opposite in the sense that CBD keeps me from getting very high on THC. When I vape the THC euphoria is not as intense and doesn't last nearly as long.
