Full spectrum THC refers to THC oil that is extracted from the whole cannabis plant, allowing the oil to maintain the full profile of active compounds in the plant, including terpenes, flavonoids, sterols, and cannabinoids like THC, CBD, CBG, and CBN. Full-spectrum products are touted as superior because cannabinoids are more effective when working together, a concept known as the entourage effect. Full-spectrum THC vape cartridges give access to the wide range of active compounds found in cannabis, and they also tend to maintain the natural flavor and aroma of the cannabis plant. Full-spectrum cannabis extracts are also called whole plant extracts.
