That leaves those touting CBD’s effectiveness pointing primarily to research in mice and petri dishes. There, CBD (sometimes combined with small amounts of THC) has shown promise for helping pain, neurological conditions like anxiety and PTSD, and the immune system—and therefore potentially arthritis, diabetes, multiple sclerosis, cancer, and more.
Although CBD oils aren’t regulated by the FDA, purchasing products stateside from one of the nine states where recreational and medical cannabis use is legal will likely result in a higher-quality product than buying one made with hemp-derived CBD oil imported from abroad, says Martin Lee, director of Project CBD, a nonprofit that promotes medical research into CBD.
All in all, current research shows us that we will experience the most significant degree of therapeutic relief when all the cannabinoids and the terpenes — essential oils that produce the plant’s aromas — are in the oil. Even adding just a little THC in CBD oil can greatly improve the medical properties because of the phenomenon known as the entourage effect.
