CBD also known as cannabidiol oil is one of many cannabinoids found in cannabis.
Cannabis is the genus name for both marijuana and hemp, and the term itself is not necessarily interchangeable with marijuana. In fact, almost all CBD oil today comes from industrial hemp, which contains negligible amounts of THC, the cannabinoid responsible for causing a high. Most strains of agricultural hemp are rich in CBD while only having less than 0.03 percent THC, making them perfect for extracting CBD oil
