Oxford nitrous crash spurs citywide sales ordinance in Lafayette County

A red-light crash at South Lamar Boulevard and University Avenue turned nitrous oxide from a fringe concern into a citywide public-safety issue in Oxford, after three pedestrians were struck at Four Corners and seriously injured.

Oxford police arrested Samuel Troy Welborn, 20, and charged him with DUI after the August 2025 wreck, which investigators said involved nitrous oxide sold in large canisters and often marketed under names such as Galaxy Gas. Chief Jeff McCutchen said the outcome was fortunate given how much worse it could have been.

The crash helped drive a new ordinance the Oxford Board of Aldermen considered on Jan. 26, 2026 and then approved unanimously Feb. 3 at City Hall. City Ordinance No. 2026-3, also identified as Ordinance 74-15, prohibits intentional consumption of nitrous oxide for intoxication and possession with intent to use it that way inside Oxford city limits.

The measure does not ban legitimate commercial or professional use. It exempts nitrous oxide used in medicine, food preparation, veterinary care, industrial work, automotive use, retail and scientific settings. It also bars sales to people under 21 and to anyone known to be using it as an intoxicant.

Oxford police said the city is focusing on the places where misuse was showing up locally. That includes convenience stores, gas stations, vape shops, smoke shops, novelty and gift shops, and other businesses where food service is not the primary business. Officers said they would visit businesses, explain the ordinance and follow up to make sure the products were removed.

McCutchen said city concerns about nitrous oxide dated back to around 2012 or 2013, when an early local case was linked to a fatal traffic accident. Breck Jones, the police department’s public information officer, said the danger is not limited to the person inhaling the gas. It has shown up in crashes, injuries and emergency responses that affect innocent drivers, passengers and pedestrians.

The local response lined up with a broader health warning. University of Mississippi researchers Andrew Yockey and Rachel Hoopsick published a 2025 study in JAMA Network Open finding that U.S. nitrous oxide poisoning deaths rose from 23 in 2010 to 156 in 2023, a 578% increase. Yockey also said, “This is not local to one area; it’s everywhere.”

University of Mississippi officials have said more than 13 million Americans have misused nitrous oxide in their lifetimes, underscoring why Oxford leaders framed the ordinance as a targeted prevention effort rather than a blanket ban. For a city that depends on downtown foot traffic, the new rule puts inhalant abuse in the same public-safety frame as impaired driving: a local risk with consequences that can spill onto Lafayette County roads in a single moment.
