• Rescheduling Impact: The Department of Justice also moved to reclassify ma*****na as a Schedule III controlled substance. This shifts cannabis closer to federally recognized medical prescriptions, moving it away from the same restrictions applied to Schedule I drugs.
Until the ATF formally publishes the updated form and instructions, the existing Form 4473 remains in circulation. You must continue to answer the controlled substance questions truthfully as currently written based on your state and federal status.
