When you CBD edibles, this process allows the CBD to rapidly become bioavailable to the user, but in turn causes the CBD to dissipate quickly and leave the body. How long does CBD edibles take? When you ingest CBD edibles, it takes longer to become bioavailable because it has to pass through the digestive system and be absorbed into the body through the small intestine. These CBD edibles include CBD Gummies, CBD Capsules, CBD Tablets, CBD Cookies and other consumables. One of the benefits of these types of CBD products is that the cannabidiol is pre-measured, so you know exactly how much CBD is in each serving.
