Ohio Senate Bill 55 addresses cannabis-related operating-under-the-influence law and admissible evidence for vehicles and watercraft. The Senate passed it 28-0 on October 8, 2025. It was referred to the House Judiciary Committee on October 15, 2025, with House hearings recorded in February 2026. The legislature's status report reflecting action through November 9, 2026 still lists it as awaiting House action. It has not become law. [1][2][4][6]
The proposal would remove existing per se OVI provisions based on marijuana-metabolite measurements and introduce evidentiary rules allowing a court or jury to infer impairment from specified test results. A per se violation and an inference are different legal mechanisms: the former makes a specified prohibited concentration a basis for the offense; the latter supplies evidence a fact-finder may consider. Readers should consult the Senate-passed text for exact thresholds and language, which can change as a bill moves. [3][5]
The official committee record includes support from civil-liberties and legal organizations and opposition from DUID Victim Voices. That record is useful because road safety, testing standards and defendants' rights should all be examined openly. A unanimous Senate vote does not end the debate or substitute for House passage and the remaining enactment process. [4]
Our position.
Legalization advocacy should support safe roads and reliable evidence together. Ask legislators how the proposed standards are justified, how testing is performed and challenged, and how the law avoids punishing lawful use without adequate evidence of the charged offense. Do not treat a proposed numerical limit as permission to drive after using cannabis. Impaired driving remains prohibited, and this pending bill creates no present-day safe harbor.
Questions and next steps.
Read the Senate-passed version and submit specific questions on testing reliability, due process and road safety to the House Judiciary Committee.
