Buying online is less reliable still because there’s no regulation or standardization. What you see on the label may not be what you are getting. A 2017 study in JAMA found that of the 84 CBD products researchers bought online, 43% had more CBD than indicated, while 26% had less, and some had unexpected THC. “There’s a 75% chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.
Full-spectrum hemp oil refers to when the pure oil extracted from hemp contains all the same cannabinoids and compounds found in the original hemp plant. Unlike isolated or synthetic cannabinoids, full-spectrum hemp oil contains an array of cannabinoids, as well as many essential vitamins and minerals, fatty acids, protein, chlorophyll, fiber, flavonoids, and terpenes.
There are a number of potential solvents that can be used to extract CBD oil from the hemp plant. Some companies choose to use dangerous chemical solvents in their extraction process. However, this opens the end user to residual contamination from any solvent that is left unpurged from the oil. To extract our CBD oil from our hemp crops, we use supercritical CO2.
