The movement for surgical smoke safety has always been about persistence, education, and collaboration. By 2026, three more states—Delaware, Missouri, and North Carolina—joined the growing coalition of smoke-free operating rooms, proving that meaningful change often takes time but delivers lasting impact.

State Milestones
Delaware
The process started in May 2025, when Rep. Melissa Minor-Brown introduced HB 173. After months of advocacy and hearings, Governor Matt Meyer signed the bill on August 25, 2025. The law takes effect April 1, 2026, making Delaware the 20th state to mandate the use of smoke evacuation systems.
Missouri
Advocacy efforts stretched across several sessions, with language finally added to HB 402 in mid-2023. Governor Mike Parson signed the bill in July 2023, giving hospitals and ASCs time to prepare. The law officially takes effect January 1, 2026.
North Carolina
Nurse advocates introduced HB 390 in March 2025. The bill moved quickly through the legislature and was signed into law by Governor Josh Stein on July 1, 2025, with implementation required by January 1, 2026—giving facilities just six months to prepare.
By comparison, hospitals typically need six to eighteen months to fully prepare for smoke evacuation compliance, including policy development, staff education, equipment selection, and workflow integration. North Carolina’s timeline underscores how rapidly requirements can take effect and the importance of early planning.
Education Before Action
These timelines remind us that the “smoke evacuation” movement isn’t always about speed. Legislation takes root when education has time to sink in. Nurses, hospital leaders, and policymakers needed space to understand the dangers of surgical smoke, weigh solutions, and build consensus. By allowing time for education and dialogue, these states ensured that their laws were not just mandates, but commitments backed by informed support.
Leadership That Matters
The signatures of Governors Meyer, Parson, and Stein represent more than political acts—they symbolize positive action for surgical staff and patients alike. Each governor’s approval moved us closer to a healthier OR and a healthier world, reinforcing that protecting perioperative teams is a bipartisan, human-centered priority.
Momentum That Builds
With Delaware, Missouri, and North Carolina joining the ranks, 20 states now stand smoke free. Each milestone reflects years of advocacy, education, and persistence. The movement continues to grow, not through quick wins, but through deliberate steps that ensure every stakeholder understands the importance of clean air in the OR.
