CBD oil

CBD oil is the common consumer name for a liquid product made by dissolving a hemp extract or cannabidiol isolate in a carrier oil.

The extract is typically obtained from hemp flower using carbon dioxide or ethanol, then blended with a carrier such as medium-chain triglyceride oil, hemp seed oil, or olive oil. The carrier makes the fat-soluble cannabinoids easier to measure and swallow and influences how they are absorbed. Most CBD oil is sold in dropper bottles and taken by mouth, either under the tongue or swallowed. The term is often used interchangeably with tincture, even though traditional tinctures are alcohol-based.

Labels should state the total milligrams of cannabidiol in the bottle, the concentration in milligrams per milliliter, the extract type, and a batch number tied to a certificate of analysis showing cannabinoid content and contaminant testing. Isolate contains 0.0% THC; full-spectrum extract may contain up to 0.3% THC by dry weight under the 2018 Farm Bill; broad-spectrum has THC removed to the limit of detection. CBD oil should not be confused with hemp seed oil, which contains negligible cannabinoids. The U.S. Food and Drug Administration has not approved CBD oil as a dietary supplement or food ingredient.
