A. The Agriculture Improvement Act of 2018 changes certain federal authorities relating to the production and marketing of hemp, defined as cannabis (Cannabis sativa L.), and derivatives of cannabis with extremely low (less than 0.3 percent on a dry weight basis) concentrations of the psychoactive compound delta-9-tetrahydrocannabinol (THC). These changes include removing hemp from the Controlled Substances Act, which means that it will no longer be an illegal substance under federal law. However, Congress explicitly preserved the agency's current authority to regulate products containing cannabis or cannabis-derived compounds under the FD&C Act and section 351 of the Public Health Service Act. Please see the FDA’s statement on the signing of the Agriculture Improvement Act of 2018.
