Importance Of Decarbing Weed
Decarbing Weed activates the THC and CBD molecules by breaking down the THCA into THC, and CBDA to CBD, as an example. Decarbing Weed also increases the bioavailability of cannabinoids, meaning that more cannabinoids are available for absorption when ingested, inhaled, or applied topically.
