Data story · Oklahoma syringe services, 2021 to 2026
The 2021 law that let groups hand out sterile syringes had a five-year sunset, and lawmakers let it pass without renewal. Here is what the state’s own data and decades of research say about bringing it back.
Chapter01
In 2021 Oklahoma made it legal for registered groups to hand out sterile syringes. Lawmakers wrote a five-year expiration date into the law. It ran out on July 1, 2026, and nobody renewed it.
The bill had an unusual starting point. Its sponsors filed it to protect police officers from needle-stick injuries. The expiration date was meant to make lawmakers come back after five years and check whether the programs had helped. One of those sponsors, former Rep. Carol Bush, now says: “I’m not sure that conversation ever happened.”
These are the programs’ own counts. They reported them to the Healthy Minds Policy Initiative, and no one has audited them. The programs also reported 1,212 overdose reversals with naloxone they gave out. We list that figure here but don’t rely on it anywhere in this story.
Chapter02
Oklahoma has had the highest hepatitis C death rate of any state every year from 2017 to 2023. In 2023, 447 Oklahomans died with hepatitis C listed as a cause of death. That rate was 8.94 per 100,000, 3.5 times the national rate.
The next-highest jurisdiction in 2023, District of Columbia, was at 7.56. Across those seven years, 3,681 Oklahomans died with the virus. Hepatitis C is curable, and it spreads through blood.

When doctors report a new hepatitis C infection, they record how the person was exposed. In 2023, that information was missing for 3,230 cases. Of the 1,736 cases where it was recorded, 43% involved injecting drugs, more than any other risk on CDC’s list. These are national figures; CDC does not publish them by state.
Oklahoma also reports more new chronic hepatitis C cases per person than any other state that reports them: 145.5 per 100,000 in 2023, against 36.2 nationally.

Read this chart carefully. Oklahoma’s rate went from 55.1 to 145.5 in two years. A rise in reported cases can mean more testing as well as more infection, and these numbers can’t tell the two apart. We treat this as evidence of how many people need care, not as proof that the virus is spreading faster.
Chapter03
Syringe programs are among the most studied public health measures. The research supports them, though not equally on every outcome. We show where the evidence is strong and where it is thin.
For HIV, the higher-quality studies in a 2014 meta-analysis found 58% lower risk of infection for people using syringe programs. For hepatitis C, a 2017 Cochrane review found that syringe access alone has weak evidence. Combined with medication for opioid addiction (methadone or buprenorphine), it found a 74% lower risk. That combination is the point. A syringe program is often the first health service a person who injects drugs will walk into, and it is where they can be offered that treatment.

How strong is this? Almost none of this research is randomized; you can’t randomly deny people clean needles. Most estimates come from comparing people who used programs with people who didn’t, and those groups can differ in other ways. That is why every estimate above shows its interval. The “five times” figure is widely repeated, but it comes from a single city’s study. The Baltimore trial suggests the referral itself matters: treatment entry rose most when programs offered active help such as rides to appointments.
Chapter04
The clearest evidence of what syringe access prevents comes from places that went without it.
Scott County, Indiana · 2014–2015
215
HIV infections in one rural county’s outbreak
Indiana had no legal syringe program. An outbreak spread through a network of people injecting prescription opioids, and 92.3% of those diagnosed also had hepatitis C. The state’s first syringe program opened only after the governor declared a public health emergency on March 26, 2015. A Yale model estimates that responding by January 2013 could have prevented at least 127 infections.
Kanawha County, West Virginia · 2019–2021
85
people in an HIV outbreak, after the county health department suspended its syringe program in March 2018
Before the outbreak, the county diagnosed fewer than five HIV cases a year among people who inject drugs. In the first ten months of 2019 it diagnosed 11. When CDC investigators interviewed people who inject drugs, they reported sharing syringes “mainly because of limited access to sterile syringes after SSP closures.”
What these cases can and can’t show. Neither outbreak proves that one closure caused it. Kanawha’s also overlapped with the COVID-19 pandemic. But both fit the same pattern: shared syringes, then a fast-moving outbreak, in places without legal access. Hepatitis C and HIV both spread through shared needles, and Oklahoma already has the highest hepatitis C death rate in the country.
Chapter05
Oklahoma now sits among neighbors that mostly restrict syringe access too. Colorado and New Mexico authorize it by statute. Arkansas allows it indirectly, Texas allows a single county pilot, and Kansas and Missouri don’t authorize it at all.

Oklahoma’s 2023 hepatitis C death rate (8.94) is about double the next-highest of its neighbors, New Mexico (4.32). States differ in many ways besides their syringe laws, so this map shows where Oklahoma stands. It doesn’t prove what caused the gap.
A note on overdoses. Overdose deaths are falling across the country, and Oklahoma is no exception. As of May 2026, its 12-month count was 40% below its May 2023 peak. The U.S. as a whole was 41% below its own peak. The highest rates in the region are in Colorado and New Mexico, both states where syringe programs are legal. That pattern follows the drug supply: fentanyl reached western markets later. Syringe laws don’t explain it either way, so we don’t use overdose deaths to argue for syringe programs. What the programs add on overdoses is naloxone, the overdose-reversal drug, and the people trained to use it.

Chapter06
Oklahoma tried this for five years. The sunset was meant to prompt a review, and one of the law’s own sponsors isn’t sure it ever happened. Here is what a renewal should do.
Oklahoma has had the country’s highest hepatitis C death rate every year in the data. It doesn’t need to wait for its own Scott County before acting.
