The 2018 United States Farm Bill removed the hemp plant and all "derivatives, extracts, cannabinoids, isomers, acids, salts, and salts of isomers, whether growing or not, with a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis,"  including CBD, from the Controlled Substances Act, making them legal to manufacture in the United States. The FDA retains regulatory authority over hemp-derived CBD, while the DEA is not involved in the regulation of legally-compliant hemp and hemp products. The 2018 Farm Bill requires that research and development of CBD for a therapeutic purpose would have to be conducted under notification and reporting to the FDA. In the United States, hemp-derived CBD is legal to sell for industrial purposes or as a cosmetics ingredient, but under FDA regulation it cannot be marketed for medical use or as an ingredient in food, dietary supplements, or animal feed. FDA warning letters
From 2015 to May 2022, the FDA issued dozens of warning letters to American manufacturers of CBD products for false advertising and illegal interstate marketing of CBD as an unapproved drug to treat diseases, such as cancer, osteoarthritis, symptoms of opioid withdrawal, Alzheimers disease, and pet disorders. Chemical analysis of CBD products found that many did not contain the levels of CBD claimed in advertising.In December 2020, the Federal Trade Commission (FTC) initiated a law enforcement crackdown on American companies marketing CBD products as unapproved drugs.
This proposal is based on an initial literature review on the safety of low dose CBD published by the TGA in April 2020. Epidyolex was approved, for the adjunctive therapy of seizures associated with Lennox-Gastaut syndrome or with Dravet syndrome, on 18 September 2020, and added to the ARTG on 21 September 2020. Bulgaria
In 2020, Bulgaria became the first country in the European Union to allow retail sales of food products and supplements containing CBD, despite the ongoing discussion within the EU about the classification of CBD as a novel food. But there exists a legal gap because of the lack of a legally-permissible minimum amount of THC in the products containing cannabinoids. Canada
In October 2018, cannabidiol became legal for recreational and medical use by the federal Cannabis Act. As of August 2019, CBD products in Canada could only be sold by authorized retailers or federally licensed medical companies, limiting their access to the general public. Nonetheless, with online delivery services and over 2,600 authorized cannabis retail stores as of October 2021, accessibility has steadily increased over time. The Canadian government states that CBD products "are subject to all of the rules and requirements that apply to cannabis under the Cannabis Act and its regulations." It requires "a processing licence to manufacture products containing CBD for sale, no matter what the source of the CBD is, and that CBD and products containing CBD, such as cannabis oil, may only be sold by an authorized retailer or licensed seller of medical CBD."
