Before we get too deep into the possible effects CBD might have, let’s first discuss what it is. CBD, or cannabidiol, is the second most prevalent active ingredient in cannabis (marijuana) [gasp]. I know what you’re probably thinking [fill in some kind of joke about stoner expectations], but CBD is actually derived from hemp. What this means, in practice,is that there isn’t a sort of “high” you feel when taking CBD by itself. That “high” actually comes from THC, but to be legally considered CBD, a product has to have no more than 0.3% traces of THC.
