Combating Illicit Xylazine Act
This bill regulates xylazine under the Controlled Substances Act (CSA).
Xylazine, also known as tranq , is a nonopioid sedative and pain reliever that is approved for use in animals. Recently, the Drug Enforcement Administration (DEA) has reported an increase in trafficking of fentanyl mixed with xylazine.
This bill adds xylazine, including its salts, isomers, and salts of isomers, to schedule III of the CSA. Schedule III controlled substances, including anabolic steroids, buprenorphine, and ketamine, have less potential for abuse than a schedule I or II substance, have a currently accepted medical use, and have low or moderate risk of dependence if abused.
Under the bill, manufacturing, distributing, or dispensing xylazine, or possessing with intent to manufacture, distribute, or dispense xylazine for illicit use is subject to criminal penalties under the CSA. The bill also requires xylazine transactions to be tracked in the drug reporting system maintained by the DEA.
The bill exempts from registration under the CSA persons and entities that possess xylazine (1) lawfully dispensed by a veterinarian or pharmacy and (2) for an animal or for use in certain animal-control or wildlife programs.
The bill also exempts xylazine manufacturers from the CSA's physical security requirements.
Finally, the bill requires the DEA, in coordination with the Department of Health and Human Services (HHS), to provide Congress with a report on how the agencies previously determined whether xylazine should be a controlled substance, including the full text of HHS's recommendations to the DEA for scheduling xylazine.

Where is it in the process, and what happens next?
4 steps remain before this bill could become law.
The record's latest action, on April 15, 2026: Placed on Senate Legislative Calendar under General Orders. Calendar No. 372.
- Clearing the committees it was referred to, and being scheduled for a floor vote
- Passage by the Senate
- Passage by the House
- The President's signature. If the President vetoes it, two-thirds of both chambers must vote to override.
How likely is it to become law?
Civibrief does not forecast outcomes and this page has no opinion about this one. What the record supports is a base rate, which is a fact about the whole pile, not a prediction about this measure.
In the 118th Congress (2023-24), 274 of the 16,565 bills and joint resolutions introduced became law, about 1.7 percent. That count covers every measure at every stage, including the many that never left committee.
This one is not there yet: 4 steps are still outstanding, listed above.
Has anyone actually voted on it?
No. No roll call in this Congress cites this measure. That is the ordinary outcome: most measures never reach a recorded floor vote, and a committee ends most of them simply by not acting.
A vote is not the only thing that happens to a measure. Hearings, markups, and referrals are all recorded actions, and none of them is a vote of the full chamber.
Who is behind it?
Catherine Cortez Masto (D-NV) introduced it on February 12, 2025, and 35 members have since signed on as cosponsors.
They come from both major parties: 15 Democrats, 19 Republicans, 1 independent.
Cosponsoring is a formal signature on the text. It is not a commitment to vote for the measure, it does not bind anyone's party, and a long list of cosponsors is a measure of attention rather than of prospects.
How long has it been in play?
It was introduced on February 12, 2025, 575 days ago. The most recent recorded action was 148 days ago, on April 15, 2026.
Measures do not carry over. Anything the 119th Congress has not finished by January 3, 2027 dies when the term ends, and has to be introduced again from the start in the next Congress.
Every answer above is assembled from this measure's own record on Congress.gov and from published counts of what Congress has passed before. Civibrief does not predict outcomes and takes no position on any measure.
