Just read your article about CBD oil and checked the label on the oil I bought 9 months ago from a legal dispensary in Pendleton, Oregon. Across from the Subway. It lists herbs and supplements long before CBD oil and it is a derivative of Hemp oil. I paid $52 for one ounce (30 ml). I had not done any research prior to my purchase and relied on the folks at the marijuana shop to sell me a good product. Buyer beware is the best advice I got from this article. I have not achieved any pain relief from this product and use about 1 ml under my tongue with the dropper in the bottle. I intend to find a full spectrum CBD oil and I hope to notice a difference in pain relief. Thanks for the great information.
