09 Apr 2021 --- A poll of 1,087 US residents conducted by Invisibly has discovered that while nearly a third of respondents have tried a cannabidiol (CBD) product, many still do not understand the difference between CBD and the closely related compounds of marijuana, such as tetrahydrocannabinol (THC). To help support the spread of knowledge about this highly regulated product, the American Herbal Products Association (AHPA) has published a Hemp Lexicon. This list of hemp-related vocabulary is intended to standardize the terminology used in the cultivation, processing, manufacturing and labeling of hemp products as defined in US federal law.
