In 2019, the cannabis manufacturer, Canopy Growth, acquired majority ownership of BioSteel Sports Nutrition, which is developing CBD products under endorsement by numerous professional athletes. The National Hockey League Alumni Association began a project with Canopy Growth to determine if CBD or other cannabis products might improve neurological symptoms and quality of life in head-injured players. Numerous professional athletes use CBD, primarily for treating pain. Legal status
Australia
Prescription medicine (Schedule 4) for therapeutic use containing two percent (2.0%) or less of other cannabinoids commonly found in cannabis (such as ∆9-THC). A Schedule 4 drug under the SUSMP is a Prescription Only Medicine, or Prescription Animal Remedy – Substances, the use or supply of which should be by or on the order of persons permitted by state or territory legislation to prescribe and should be available from a pharmacist on prescription.In June 2020, the Australian Therapeutic Goods Administration (TGA) published a consultation on a proposal to pave the way to make "low dose" CBD available to consumer/patients via pharmacists only through moving products from Schedule 4 to 3. Any products sold would need to have their safety, quality and efficacy pre-assessed by the TGA and be formally approved for sale (details to be outlined by TGA). They would be made available to over 18s only, with the maximum daily dose of 60 mg/day, up to 2% THC finished product allowed, 30-day maximum supply, plant-derived or synthetic.
The chemical formula of CBD was proposed from a method for isolating it from wild hemp. Its structure and stereochemistry were determined in 1963. Plant breeding
Selective breeding of cannabis plants has expanded and diversified as commercial and therapeutic markets develop. Some growers in the US succeeded in lowering the proportion of CBD-to-THC to accommodate customers who preferred varietals that were more mind-altering due to the higher THC and lower CBD content. In the US, hemp is classified by the federal government as cannabis containing no more than 0.3% THC by dry weight. This classification was established in the 2018 Farm Bill and was refined to include hemp-sourced extracts, cannabinoids, and derivatives in the definition of hemp. Society and culture
Foods and beverages
Food and beverage products containing cannabidiol were widely marketed in the United States as early as 2017. Hemp seed ingredients which do not naturally contain THC or CBD (but which may be contaminated with trace amounts on the outside during harvesting) were declared by the US Food and Drug Administration (FDA) as Generally recognized as safe (GRAS) in December 2018. CBD itself has not been declared GRAS, and under US federal law is illegal to sell as a food, dietary supplement, or animal feed. State laws vary considerably as non-medical cannabis and derived products have been legalized in some jurisdictions in the 2010s.
