CBD, a cannabinoid found in cannabis plants, has been around for thousands of years. Medicinal cannabis use dates back as far as 2000 BCE. However, the same source tells us that it wasn't until 1940 that a man by the name of Dr. Roger Adams discovered CBD. And even though it was discovered 20 years before THC, THC has pretty much dominated cannabis research until quite recently.
CBD users have reported improvements for several ailments and conditions, like anxiety, aging, cancer, epilepsy, and autoimmune disorders. But many people wonder, can CBD oil be used topically?
