Colorado's Prop 132 Would Make Possessing Any Amount of Fentanyl a Felony. Prosecutors Are Split.

Colorado voters will decide in November whether possessing any amount of fentanyl should be a felony — a change that would also impose mandatory prison terms of eight to 32 years for distribution and remove a legal safeguard for people who did not know the substance they were carrying contained the drug.

Proposition 132 was placed on the ballot by Advance Colorado, the conservative advocacy group behind several recent state initiatives. It returned to the news this week after the Aurora City Council voted 8-2 to urge residents to reject it, with two council members siding with the proponents.

Under current Colorado law, possessing more than four grams of fentanyl is already a felony. Between one and four grams can be charged as a misdemeanor or a felony depending on whether the defendant knew the substance contained fentanyl, and at the court's discretion; under a gram is a misdemeanor. The proposition collapses that structure. Possession of one gram or less becomes a level four felony, with the conviction vacatable if the person completes a treatment program. Distribution becomes a level one drug felony with a mandatory minimum of eight to 32 years.

The quieter language may matter more. Today, someone who provides evidence that they did not know a substance contained fentanyl can have the offense treated as a misdemeanor. The measure removes that provision, leaving a person who believed they were buying a Xanax exposed to felony charges based on quantity alone.

The Cost Estimate and the Death Toll

A legislative analysis projects roughly $9 million in implementation costs as more people enter the prison system, with total state spending rising by an estimated $68 million as sentences lengthen. The proposition creates a treatment pathway a judge could use to vacate a low-level conviction, and appropriates nothing for the treatment itself.

Fentanyl was involved in 980 overdose deaths in Colorado in 2025, up from 761 the previous year, according to the state Department of Public Health and Environment. Most of the people who died were between 25 and 64.

Supporters argue that longer sentences and the treatment option together change the arithmetic of the drug trade. "The sooner you can get people into treatment, the more likely that their lives are going to be saved," Kristi Burton Brown, executive vice president of Advance Colorado, told Colorado Public Radio. Douglas County District Attorney George Brauchler said the measure strikes a balance between punishment and help, and blamed harm-reduction practices for part of the state's fentanyl problem.

Prosecutors Are Not United

Boulder County District Attorney Michael Dougherty opposes the measure on resource grounds, arguing that prosecuting low-level possession cases would pull police, prosecutors, and jail beds away from trafficking. The Colorado Criminal Justice Reform Coalition makes the funding argument: the treatment route has no appropriation behind it.

"It doesn't fund any of the things we know work, which is funding treatment and access to community resources to avoid overdoses," said Kyle Giddings, the coalition's deputy director. He predicted a second-order effect that overdose researchers have documented elsewhere — that people who fear arrest stop calling 911 when someone nearby is overdosing, which raises deaths rather than lowering them.

One council member who voted for the resolution still made the case for toughness. Councilmember Francoise Bergan said she supports prison time for users and distributors but found the proposition "so poorly written" that she could not back it.

For families weighing what a felony conviction would mean for someone in opioid addiction treatment, the practical question is whether prison improves or interrupts recovery. Colorado answers it on Nov. 3.
