i have a registtation and I have a prescription from a pain clinic. They prescribed CBD oil ( oral under the toung ) in the beginning for me , it was good but after a while it cause a stomach upset , refkex and vomiting for me. I did explaied my situation to the pain clinic and they prescribe the Decarb high CBD ( itis powder and fill it in a capsule and take it as other medications . As my experience it is more effective more than other kind of CBD because it is high % of CBD .
