Broad spectrum CBD oil contains more beneficial plant compounds from the hemp plant as compared to CBD isolate-based products. At the same time, broad spectrum CBD oil is THC-free, so you don’t have to worry about a drug test coming back THC-positive. This means that products made with broad spectrum hemp extract are the most suitable options for those who are allergic to THC or for one reason another can not have any THC in their system. It’s the best of both worlds! Also, having the additional plant compounds outside of CBD included in the oil contributes to what’s known as the entourage effect, which researchers believe plays a big role in positive outcomes from CBD usage.
