Wyoming Lawmakers File Bipartisan Bill to Reclassify Marijuana as Schedule III Substance

A bipartisan group of Wyoming lawmakers introduced legislation today that would reschedule cannabis under state law, moving it to Schedule III. This follows similar proposals being filed in Kansas, Mississippi, and West Virginia. House Bill 166 is sponsored by State Representatives Karlee Provenza (D), Jeremy Haroldson Posey (R) and J.T. Singh (R), along with State Senators Cale Case (R) and Chris Rothfuss (D). The proposal would amend multiple sections of Wyoming statute to formally list marijuana as a Schedule III substance rather than keeping it grouped with the most restrictive drugs under existing law.

As written, the bill does not legalize marijuana, nor does it create a medical marijuana program. Instead, it changes how marijuana is defined and categorized throughout state law, bringing Wyoming’s scheduling framework in line with an incoming change in federal law (President Trump signed a rescheduling executive order in December).

The legislation amends definitions tied to edible products, drug paraphernalia, forfeiture rules, probation eligibility for first-time offenders, and statutes related to cultivation and processing. In each case, the language is updated to reflect marijuana’s new placement in Schedule III rather than its current status.

The bill also repeals a conflicting provision in current statute and directs the state’s commissioner of drugs and substance control to create rules necessary to implement the change.

If approved by the Legislature and signed into law, House Bill 166 would take effect July 1, 2026.
