CBD oil refers to any number of concentrated liquid cannabis or hemp extracts consisting primarily of the non-intoxicating compound cannabidiol, commonly abbreviated to CBD. Through solvent or mechanical extraction processes utilizing carbon dioxide, ethanol or hydrocarbon solvents, crude CBD extracts are winterized and distilled then suspended and diluted with an inert carrier oil to create versatile liquid products that can be easily ingested orally, vaped, applied topically or even added to foods and beverages. CBD oil products appeal to a remarkably wide demographic seeking natural relief of common symptoms and conditions without experiencing mind-altering side effects. However, CBD extracts and consumer products currently remain largely unregulated without strict standards, with highly variable cannabinoid contents, inconsistent quality control and insufficient third party lab testing across the board. When properly sourced as a whole plant extract originating from high resin cannabis strains rather than industrial hemp biomass, CBD oils may still contain traces of the intoxicating cannabinoid THC in amounts beneath 0.3%, rendering them technically illegal in restrictive jurisdictions banning all forms of THC consumption. For maximum legal accessibility, CBD-dominant oils conversely can also be reliably extracted from legally cultivated hemp varieties specially bred to be exceptionally low in THC but rich in CBD content.
