Cannabidiol, or CBD, is the second most common cannabinoid found in cannabis. Unlike its euphoric cousin, THC (or tetrahydrocannabinol), CBD plays it cool, offering relaxing, non-intoxicating effects that lend themselves to a variety of personal and medicinal uses. Because CBD lacks the stoney side effects typical of high-THC strains, it’s a great choice for patients needing to keep a clear head while treating pain, nausea, headaches, stress, anxiety, muscle spasms, epilepsy, and more.
