Cannabidiol is one of the most critical cannabinoids contained in the cannabis plant. It exists both in agricultural hemp, as well as medical cannabis. While cannabinoids are present within several plants in nature, cannabis is the only plant known to contain CBD. CBD has the same chemical formula as THC, with the atoms in a different arrangement. This slight variance causes THC to create a psychoactive effect, while CBD does not. This fact means that when you ingest CBD for your own purposes, you will more likely experience relief of unwanted discomfort, with little or no noticeable effect on your cognitive abilities.
