Denver’s prohibition on flavored nicotine products is poised to remain on the books after voters overwhelmingly backed Referendum 310 in Tuesday’s election, solidifying one of the most closely watched flavor restrictions in the Mountain West.
As of 10 p.m., about 72 percent of counted ballots — just over 113,000 — supported keeping the city’s “flavor ban” in place. A “yes” vote upholds the ordinance passed by the Denver City Council last year; a “no” would have repealed it. With the measure tracking toward a green light, local retailers are preparing to halt sales of fruity flavored e-cigarettes and menthol cigarettes as the city begins enforcement in the coming weeks or months.
“I’m excited. I’m encouraged,” said Selena Dunham, an outreach coordinator with the Yes on 310 campaign, speaking at a watch party at Spangalang Brewery in Denver’s Five Points neighborhood. “I’m encouraged that people paid attention and that they think that the health of our children, our youth, is important.”
The vote drew statewide and national attention, including a record contribution from Michael Bloomberg to support the ban. It marks the first time Colorado voters have weighed in directly on a flavored nicotine restriction, a policy approach many public health advocates argue is key to curbing youth uptake and addressing decades of targeted marketing, particularly in menthol products.
For Dunham, the win is personal. She said a dozen members of her family have died from smoking-related illness, including an 85-year-old aunt whose funeral is Wednesday. “I think we have a lot of work to do. There’s some people that are just still totally blind to how serious this matter is,” she said, noting long-standing marketing in communities of color. “So we are making small steps, but I think we have a long way to go.”
The ordinance was challenged by opponents who placed Referendum 310 on the ballot after council passage. Industry and retail critics have argued that flavor prohibitions can push adult consumers to neighboring jurisdictions, fuel illicit sales, and hurt small businesses that rely on vape and menthol revenue. On Tuesday night, leaders of the opposition campaign were not immediately available for comment.
What the industry should expect next:
- Certification of results and a formal enforcement schedule from city regulators.
- Retail guidance clarifying definitions, sell-through timelines, and penalties.
- Rapid inventory changes, employee training, and supplier returns for covered products.
- Potential regional leakage, as consumers travel or shift purchasing patterns outside city limits.
Denver’s move aligns with a broader national trend: Several major jurisdictions, including Massachusetts and California at the state level and cities such as San Francisco, have implemented comprehensive flavor restrictions. Denver’s decisive margin suggests similar proposals in other Colorado communities could gain momentum, though the practical impacts on youth use, adult smoking behavior, and retailer viability will be closely watched in the months ahead.
Vape Observation will continue to monitor certification, enforcement details, and retailer compliance timelines as the city rolls out the policy.
