The 2018 Farm Bill legalized the production and sale of hemp and its extracts.
Hemp, by federal law, cannot contain more than 0.3 percent THC (tetrahydrocannabinol). Anything with more THC is classified as marijuana, is considered a schedule 1 drug by the Drug Enforcement Administration and is federally illegal.
Each state has it's own industrial hemp regulations regarding growing and processing.
Although legal federally, the FDA, who is in charge of implementing rules and regulations to keep food and medications safe, has not implemented any regulations for extractors or manufacturers. The result is no accountability which has resulted in a large portion of CBD products made available to consumers are not safe or accurately labeled.
