Top Takeaways:

• Denver’s ban starts: Flavored vape sales are now illegal inside city limits, pushing some adult customers to nearby cities.
• Tax base shifts: Retailers outside Denver expect gains while Denver shops warn of lost revenue, not reduced demand.
• National echo: Similar flavor restrictions elsewhere — including Massachusetts’ statewide menthol/flavored tobacco ban in 2020 — have fueled the same debate over displacement vs. deterrence.

A voter-approved ban on flavored nicotine products took effect in Denver, Colorado, on Jan. 1, banning the sale of flavored e-cigarettes and vaping products within city limits and immediately altering purchasing patterns across the metro area.

Just beyond Denver’s borders, retailers say the effects were felt almost immediately. At Tokerz Head Shop in Aurora, about a block and a half outside the city line, owner Gordon McMillon said customers from Denver have already begun making the short trip to buy flavored nicotine and vape products no longer available in Denver.

“I was in shock it passed, to be honest,” McMillon told CBS Colorado. “Just because of how many people vape in Denver. But we’re hoping to take care of everybody that doesn’t get their needs met over there anymore.”

One of those customers, Justin Morrison, said the ban has not changed his behavior — only where he purchases vapes. Morrison, a former smoker who lives in the Denver area and vapes daily, visited the Aurora shop the day after the ban took effect.

“I’m going to have to come all the way to Aurora to get them,” he said. “It’s pretty inconvenient.”

That dynamic — displacement rather than deterrence — has become a central criticism of local flavor bans. While public health advocates argue the measures are intended to curb youth vaping, opponents say adult consumers simply travel to nearby jurisdictions or turn to unregulated sources, leaving compliant retailers within the city to bear the economic cost.

Morrison said flavored vapes were instrumental in helping him quit cigarettes, a point often raised by adult users and specialty vape retailers.

“It helped tremendously,” he said. “I stopped liking the flavor of cigarettes. The taste was nasty, the smell was nasty. I switched all the way over to vapes, and it helped me stop smoking cigarettes completely.”

McMillon worries that some former smokers will reverse course. If access is too limited, they will return to combustible cigarette smoking.

“If they can’t get their vapes, some will go back to cigarettes, for sure,” he said. “I’ve asked people myself, and it’s about 50-50.”

Despite the potential boost to his own business, McMillon said he opposed Denver’s ban on principle.

“Even if it helps me over here in Aurora, I’m against it,” he said. “I feel like adults should have the rights if they want to vape or not.”

Inside Denver, more than 500 retailers were required to remove flavored nicotine products from shelves, a category many say accounted for most of their vape sales. The Denver Department of Public Health and Environment has said enforcement will include fines and possible license suspensions for violations.

Critics of flavor bans increasingly frame the issue as tax leakage. When purchases move outside city boundaries, so do local sales tax revenues — often without a corresponding reduction in overall consumption.

The debate unfolding in Denver mirrors outcomes seen in other jurisdictions that have enacted flavor restrictions, including Massachusetts’ statewide ban on menthol cigarettes and flavored tobacco products in 2020. In those cases, opponents argue that the policies redirected legal sales rather than eliminated demand.

For now, Aurora and other nearby cities remain legal alternatives for Denver consumers. Retailers outside city limits are preparing for sustained cross-border traffic, while Denver vape shops brace for a prolonged period of reduced sales, tighter enforcement, and increased competition just beyond the city line.

Whether Denver’s ban ultimately reduces youth vaping or simply pushes adult consumers — and tax dollars — down the road remains an open question, one that has followed flavor bans nationwide.
