To everyone interested in the use of CBD and Marijuana and their effects, please watch the Full CNN Documentary, Weed Part 4 with Dr. Sanjay Gupta, April 30, 2018. It's on YouTube -Cannabis Saves Lives. This is an excellent documentary and will calm your fears about using either CBD, or THC. Great research has been done and is continuing. I have no concerns about using as much CBD tincture as I need to help with anxiety and pain.
