Hi Airsmac, I just started looking into CBD tincture oil for treatment of my PN due to problems sleeping at night and itching/pins and needles when wearing shoes. I researched a bit and discussed with a friend I trust. They recommend a firm in Colorado which develops hemp based and not having THC >.03% they can ship with online order. I just started with them so no definitive results yet but it seems better. Company is among many but if you want to learn about them purehempbotanicals can be searched for and should give you basis of comparison. Very nice staff to online chat with to ask questions.
