Hemp Oil is also from the Cannabis Sativa plant but only the seed is cold-pressed to obtain the oil. It is also called Hemp Seed Oil. It is not tested for C B D content but most likely contains a small amount as it is from the Cannabis Sativa Plant. Hemp Oil is regulated in its production and is tested for THC amounts but is not tested for C B D amounts.
Since it started becoming popular roughly two years or so ago, the general consensus has always been that since CBD oil from top brands does not contain the psychoactive properties of THC, it is therefore legal. Unfortunately, its legality is much more nuanced because of conflicting federal laws and new court cases. What is clear is that in one of the most recent court decisions on the topic, Hemp Industries Assoc. v. DEA, which came out on April 30, 2018, the US Court of Appeals for the Ninth Circuit found that Section 7606 of the 2014 US Farm Bill (the “Farm Bill”) preempts the Controlled Substances Act (CSA), the federal law which designates marijuana as a Schedule I substance (along with heroin and cocaine) making it illegal to possess or use. This means that when there is conflict between the CSA and the Farm Bill, the Farm Bill wins out.
