CBD Oil from hemp patented in 1942 (during Pot Prohibition)!MaudyGrunch (3639883) writes "I am a medical marijuana patient in CA who has been using oils made from high-CBD strains. One of the hottest products currently is CBD Oil. There is a huge movement underway to legalize the high-CBD strains used to treat childhood epilepsies. Imagine my surprise to find a CBD Oil Patent from 1942. (That was during the pot prohibition) http://1.usa.gov/WYe3Js
The patent was filed in 1940 and awarded to Roger Adams of Urbana IL in 1942. He called the end product "red oil", which he also states is a commonly known end-product of hemp. The patent even gives an explanation of the process, which seems to me to be very similar to the articles and discussions about current techniques. (And, yes, I know there are many other cannabis-related patents. I just had not seen one describing BHO extraction over 70 years old.) Are there any CBD Oil makers out there who care to comment about Mr. Adams' extraction process?
