Some research has suggested that full-spectrum can create the “entourage effect”, which may boost the effects of CBD. Broad spectrum is similar to regular CBD oil in the fact that it contains no THC. Although the THC content is removed, other elements of the hemp plant are included. These include trace elements of other cannabinoids and terpenes. Users prefer broad-spectrum when they want the other cannabinoids and terpenes from the hemp plant with the exemption of THC.
