Cannabinoid and Industrial Hemp Safety

Following implementation of the Hemp Farming Act, part of the Agricultural Improvement Act of 2018 (aka the “2018 Farm Bill”), public interest in hemp-derived products has increased rapidly. To aid industry in potential future marketing of cannabidiol (CBD) in food and/or dietary supplements across the US, ToxStrategies has been conducting systematic safety evaluations and testing programs to support future regulatory submissions. Specific areas of experience include assessment of CBD manufacturing conditions and toxicological safety, to support future Generally Recognized as Safe (GRAS) determinations or New Dietary Ingredient Notifications (NDINs), as well as the safety profile of naturally occurring CBD in hemp food products.

ToxStrategies has extensive knowledge of available data on cannabinoids and other hemp-derived products, including systematic screening of more than 4,500 safety-related studies and publication of a literature review protocol for the systematic mapping of published literature on CBD. In addition, ToxStrategies continues to monitor regulatory developments in the area of hemp-derived products and participates in relevant trade associations, such as the Council for Responsible Nutrition (CRN) and the Association of American Feed Control Officials (AAFCO).
