In December 2022, the U.S. Congress passed an omnibus spending bill that included the Medication Access and Training Expansion (MATE) Act. This new law requires prescribers of controlled substances, including dentists, to complete eight hours of one-time training on safely prescribing controlled substances in order to receive or renew their registration with the U.S. Drug Enforcement Administration (DEA). This new requirement goes into effect on June 27, 2023. --
