I would recommend starting with a whole plant extract of CBD rich cannabis in tincture format. Dosage will vary, but generally you would apply a few drops under the tongue and let that dissolve in your mouth. Wait half an hour and apply a few more drops. There are so many different varieties and growing methods, that I would also suggest trying several types of cannabis and decide what works best for you. Vaporization will provide more immediate results and topicals might also be beneficial for your neuropathy.
