CBD, or cannabidiol, is one of about 100 active compounds found in hemp. Unlike the more well-known cannabinoid THC, CBD does not cause intoxicating or euphoric effects.
From 1938–2018, with only a few exceptions, hemp was illegal to grow, possess, or use for research in the US. In 2018, revisions to the Farm Bill legalized the growth of so-called industrial hemp, which contains less than 0.3 percent—what can be called trace amounts—of THC. (All of the industrial hemp used in the production of CBD distillate for whisl CBD vapes is grown and sourced in the US, in states including Oregon, California, New York, and Pennsylvania.)
The Farm Bill also federally legalized hemp-derived CBD; however the US Food and Drug Administration (FDA) has not yet created a regulatory pathway for approval of products that contain CBD. This includes CBD confections, softgels, oils, beverages, and topicals, as well as CBD vapes.
In the absence of that federal regulatory pathway, CBD producers and consumers must rely on state-level regulations to guide manufacturing, sales, distribution, delivery, and other practices.
