It depends on the way you consume CBD oil, and the type of oil that is used as base. Sublingual usage, where you place a few drops of CBD oil under your tongue and hold it there for 30-60 secs makes CBD enter your blood stream much faster and you can feel the effects within minutes. Whereas when you directly consume it, CBD is processed by your liver and thus the effects set it late, however the effects also last longer, and this method is suitable for people who deal with chronic pain and want long lasting effects. Cannavedic’s CBD oil are prepared with MCT coconut oil as base which is easy for the liver to process, thereby increasing the bioavailability of CBD and also helps with quick setting in of the effects.
