Cannabidiol can be taken into the body in multiple ways, including by inhalation of cannabis smoke or vapor, as an aerosol spray into the cheek, and by mouth. It may be supplied as CBD oil containing only CBD as the active ingredient (no included tetrahydrocannabinol [THC] or terpenes), a full-plant CBD-dominant hemp extract oil, capsules, dried cannabis, or as a prescription liquid solution.[2] CBD does not have the same psychoactivity as THC,[9][10] and may change the effects of THC on the body if both are present.[7][8][9][11] As of 2018, the mechanism of action for its biological effects has not been determined.[8][9]
Along those same lines, most over-the-counter medications have side effects. At this point, the side effects from CBD have been very minimal and very minor. There have been some complaints of tiredness, upset stomach and a few cases of diarrhea. Outside of those few side effects most people have stated they have encountered minor side effects or none at all.
And now, onto the thorny issue of legality. The simple answer to the question is yes — if it is extracted from hemp. The 2014 Farm Bill established guidelines for growing hemp in the U.S. legally. This so-called “industrial hemp” refers to both hemp and hemp products which come from cannabis plants with less than 0.3 percent THC and are grown by a state-licensed farmer.
There’s still a lot of unknown territory, but early evidence for CBD’s efficacy is more than enough to justify further large-scale clinical studies — some of which are already in the works. These studies also point to the variety of effective ways to take CBD. This is an important point to keep in mind if you find yourself shopping for CBD products and wondering if the best CBD for pain is a topical, a tincture, or a vape product.
Since the loosening of legal policy around cannabis and the growing evidence in support of its health benefits, CBD oil has become an integral part of a lot of peoples supplement stack, used as a recovery aid by helping to improve sleep and reduce exercise-induced inflammation. Personally, I’ve been taking it for a few weeks have felt real, tangible improvements in my sleep quality.
