Fentanyl and Xylazine Test Strip Vending Machines

A fentanyl test strip vending machine puts drug-checking supplies within reach at any hour, usually free and usually next to naloxone. The strips are cheap and simple; what makes a program work is the law it runs under, how it pays for stock after the 2026 federal change, how the packs vend, and what the user is told about the strip’s limits. Facts are stated as of October 2026.

Quick answer

• What they do: fentanyl test strips (FTS) and xylazine test strips (XTS) show whether a substance contains the drug, within minutes. They do not show how much, and a negative is not a safety guarantee.
• State law (LAPPA, August 2025): FTS are outside paraphernalia penalties, for at least some people, in 47 states + DC + 4 territories; XTS in 34 states + DC + 4 territories. Iowa, North Dakota, Texas and the US Virgin Islands had no exception.
• Federal money: allowed from April 2021, barred from 24 April 2026 for strips “intended for use by people using drugs”. Naloxone and its distribution boxes are still fundable.
• Programs already vend them: New York State (MATTERS), Baltimore, Howard County MD, Boston, New York City, a Cincinnati service, Pennsylvania and VA sites.
• Machine design: one pack per release, strips paired with naloxone, instructions and a QR code to a video, and per-period limits where the program wants them.

What test strips are, and what they cannot tell you

A fentanyl test strip is an immunoassay strip, read like a home pregnancy test: dissolve a small amount of the substance (or residue) in water, dip the strip, read the lines. CDC describes FTS as “easy to use, require minimal training, and return a result within minutes”, and notes they can detect fentanyl and many fentanyl analogues in opioids, stimulants or prescription medications. Xylazine strips work the same way for the veterinary sedative xylazine. CDC notes that “naloxone will not reverse the effects of xylazine”, but should still be given in any suspected overdose because xylazine is often combined with opioids.

The limits belong on the machine and in the pack, because nobody is standing beside the user to explain them:

Limit	What the evidence says	What the instructions should say
Presence, not amount	A strip reads positive above a detection threshold; it does not measure dose	A positive means “fentanyl is there”; it does not tell you how strong
Potent analogues	Laboratory testing (Halifax et al., 2024) found reduced sensitivity to carfentanil, especially in later manufacturing lots	A negative does not mean safe. Carry naloxone and don’t use alone
Lot-to-lot variation	The same study found 2021 lots “an order of magnitude less sensitive” to fentanyl than 2017 lots	Program staff should check the lot and supplier when restocking
False positives	Diphenhydramine, lidocaine, MDMA and methamphetamine caused false positives in the same study	Dilute: CDC advises 1 mg or less of drug per 1 mL of water; methamphetamine needs heavy dilution
Xylazine strip cross-reactivity	A 2025 laboratory comparison of six XTS products (Davis et al.) found lidocaine caused false positives on some brands, and detection thresholds varied between brands	Treat a faint or unexpected XTS positive with caution; wound care and naloxone still apply

None of this argues against vending strips; it argues for good instructions and naloxone in the next coil. A 2026 study of FTS distributors in Kentucky, Ohio and New York (Gelberg et al.) named vending machines among the “innovative distribution methods” and found training varied widely: a machine has to carry that training itself.

Is it legal to vend fentanyl and xylazine test strips?

This is a summary for planning, not legal advice. Rules change; confirm with the regulator where the machine will stand.

In the US the question is state paraphernalia law. Many state laws grew from a 1979 model drug paraphernalia act, enacted by 38 states by 1987, which listed equipment for testing or analysing controlled substances as paraphernalia. Since 2018, 28 states have amended their definitions to remove some or all drug checking equipment. The Legislative Analysis and Public Policy Association (LAPPA) tracks the result:

Item (LAPPA, research current to August 2025)	Jurisdictions where possession or use is not potentially subject to paraphernalia penalty, for at least some individuals	Change since January 2024
Fentanyl test strips	47 states, DC and 4 territories	+2 (Idaho, Indiana)
Xylazine test strips	34 states, DC and 4 territories (a rule was proposed but not adopted in Ohio)	+4 (Georgia, Indiana, Louisiana, Wisconsin)
Any drug checking equipment, any adulterant	32 states, DC and 4 territories	+3 (Georgia, Indiana, Louisiana)
No exception for any drug checking equipment	Iowa, North Dakota, Texas, US Virgin Islands	—

Three cautions for a machine operator:

1. “For at least some individuals” matters. In nine of the 52 FTS jurisdictions, LAPPA says the strips may still be penalised depending on who holds them or how they are used. In some states the exception covers only syringe services program staff.
2. LAPPA’s counts are about possession and use. The model act also made it an offence to “deliver” paraphernalia. Check whether your state’s exception covers giving strips out, and through what kind of organisation.
3. XTS lag FTS. The xylazine strip list was 13 states shorter than the FTS list as of August 2025. A machine that carries both needs both checked.

Outside the US, ask the local equivalent: are drug-checking supplies lawful to possess and to supply, and through whom? We found no Australian test-strip vending program as of October 2026.

KioskForce builds the machine to the access rule, limits and records you specify. We do not certify that a test-strip program is lawful where it stands; your counsel and health department decide that.

Federal funding: from yes in 2021 to no in 2026

Date	Change	Source
7 April 2021	CDC and SAMHSA announce that grantees of CDC’s Overdose Data to Action and SAMHSA’s State Opioid Response programs may use those funds to buy fentanyl test strips	CDC/SAMHSA via AHA News
29 July 2025	SAMHSA Dear Colleague letter signals a “clear shift away from harm reduction”, following the Executive Order “Ending Crime and Disorder on America’s Streets”	Referenced in the April 2026 letter
1 December 2025	SUPPORT for Patients and Communities Reauthorization Act signed; NACo reports state and tribal grants may cover access to fentanyl and xylazine test strips	NACo
24 April 2026	SAMHSA letter: “No HHS funding can be used … to purchase or distribute … Fentanyl test strips or any other substance test kits, including xylazine and medetomidine test strips, intended for use by people using drugs”	SAMHSA

The April 2026 letter has two details that matter for a machine budget:

• What is still fundable includes “the purchase and distribution of opioid overdose reversal medications (OORMs) such as naloxone and nalmefene”, sharps disposal kits, wound care, FDA-approved home HIV and hepatitis tests, condoms and “Distribution mechanisms (e.g., bags or metal boxes/containers) for OORMs”.
• A footnote says the test-strip ban does not apply to law enforcement, EMS, public health officials or healthcare professionals using testing in their professional duties, “or as specifically authorized by the program statute”. How that interacts with the 2025 SUPPORT reauthorisation is a question for your grant officer, not your machine supplier.

The practical result is a split budget: naloxone and the cabinet from fundable lines, strips from state, county, opioid settlement or private money (Howard County, Maryland, funds its machines from its Opioid Restitution Fund). Per-product dispense records let each funder see only what it paid for.

Which programs vend test strips?

Program	What it vends	Access	Source
New York State, MATTERS network (15 machines evaluated; 30 operating by January 2026)	Naloxone, FTS, XTS and other supplies	Anonymous, no registration, 24/7	University at Buffalo, January 2026
Baltimore City Health Department (machine at Charm City Care Connection)	13 supply types including Narcan, FTS and XTS	Code from staff, or scan the QR code on the machine; “no personal information is required”	Baltimore City
Howard County, Maryland (2 machines, July 2026)	Two-dose naloxone kits; fentanyl, xylazine, barbiturate and medetomidine test strips; condoms	Free, anonymous, 24/7; QR codes link to overdose prevention training	MACo Conduit Street
Boston (4 machines announced June 2026)	Naloxone, safe injection kits, FTS	Sited at harm reduction, homeless services and medical program sites	City of Boston
New York City public health vending machines	Naloxone, FTS, hygiene kits, condoms; syringes in select machines	Enter a ZIP code; multilingual instructions	NYC311
Caracole, Cincinnati	Naloxone, fentanyl and drug test strips, HIV self-tests, kits (no syringes)	Brief sign-up survey by phone or in person, then a personal code once a week for 90 days	Caracole
Penn State “smart” machines (2, central Pennsylvania)	Hygiene, wound care, safer sex kits, test strips, naloxone	Touchscreen registration; 2,755 drug testing strips in a year	Zhang et al., 2026
VA, California (15 machines)	FTS and XTS, syringes, safer sex, wound care; naloxone added after launch	Barcode-based user access	Rife-Pennington et al., 2026

Volumes are real. In New York State’s evaluation, monthly medians were 529 naloxone kits, 245 FTS packages and 169 XTS packages, and nearly half of all items left the machines outside business hours. An outdoor, phone-registration machine in Ohio (Arendt, 2023) dispensed 10,155 fentanyl test strips and 3,360 naloxone doses in its first year.

Packaging and coil sizes for strip packs

A single strip in its wrapper is light, flat and flexible, the hardest shape for a spiral coil to release cleanly. Vend a pack, not a single strip:

Pack format	How it vends	Notes
Small carton of several strips plus an instruction leaflet	Cleanly from a coil sized to the carton	Best default; the leaflet carries the dilution and “negative isn’t safe” messages
Stiffened bag (strips + card insert + water cup)	From a coil if the card keeps it flat and rigid	Cheap to assemble in-house; check it does not fold in the coil
Combined kit: naloxone + strips	One wide coil, one vend	Simplest for the user; harder to split costs between funders
Loose single strips	Unreliable in a coil	Avoid

On our compact wall-mount machines, coil pitch is configurable per selection, so narrow coils (about 40–50 mm) for slim packs and wide coils (about 70–90 mm) for naloxone cartons sit in the same cabinet; our public health configurations use 40–60 mm coils for drug test kits and 60–80 mm for naloxone. Send a sample of each pack exactly as it will be loaded: if a supplier changes the pack, the coil pitch may need to change too.

Check the strip manufacturer’s storage range and expiry on the box. Compact wall-mount machines are ambient, so the room sets the temperature. If naloxone shares the cabinet, the naloxone label (2–25 °C, never frozen) is the stricter constraint, and the naloxone vending machine guide covers siting and optional temperature monitoring.

Instructions on the panel, in the pack and behind a QR code

The machine is the only educator present, so the instructions do the work a staff member would:

• On the pack: how to dissolve and dip, how long to wait, how to read the lines, the dilution rule for methamphetamine, and that a negative is not a guarantee.
• On the panel: a short “how to use this machine” sequence, a QR code to a demonstration video, the service phone number and the machine’s ID for fault reports. Howard County’s machines carry QR codes linking to overdose prevention training.
• On a touchscreen (optional): our compact machines take a 7- to 32-inch Android touchscreen that can play the video, or run screen-free with a QR code only.
• Language: NYC machines carry multilingual instructions; put the program’s main community languages on the panel and in the video.

Pairing strips with naloxone in one machine

Every program in the table also vends naloxone, for three reasons:

1. A positive result needs an action. The person can choose not to use, use less, not use alone, or keep naloxone ready, and the naloxone is in the next coil.
2. A negative result is not proof. The strip’s blind spots (potent analogues, lot variation) mean naloxone is the backstop either way.
3. Allocation. A 2025 simulation model (Zafarnejad et al.) found a base-case optimal split of machine capacity of about 48.5% FTS, 26.2% naloxone and 25.3% safer injection kits, shifting with local fentanyl prevalence and how willing people are to use strips. Treat that as a starting point and adjust to your own dispense data after the first months.

Under the April 2026 federal letter, keeping naloxone and strips as separate selections also keeps the naloxone in the fundable column.

Quotas and access control

The programs above span the full range: no information at all (New York State, Howard County), a ZIP code (New York City), a code from a QR scan with no personal details (Baltimore), a short sign-up survey and a weekly limit (Caracole), and a barcode inside a health system (VA). More control gives more data and more friction.

Every release on our machines is one controlled unit at a time from locked stock, with a per-vend limit and, if wanted, a per-person limit per period counted against a code in the cloud. Registration and any questions happen on the user’s phone or the optional touchscreen, and the machine only sees a code. That is how our HIVConnect and MyTest machines work: a few questions on the phone, a code released at the machine, a per-person quota (MyTest allows up to four kits a month) and an optional follow-up survey. We have not supplied a test-strip machine; the same platform and controls are what a test-strip program needs. The design choices for limits are in controlled dispensing on harm reduction vending machines, and the questions worth asking (first supply or refill, whether the last strips were used, ZIP or postcode) are in on-screen questions and forms.

What to specify if you are buying one

1. Products and packs: each strip pack, naloxone carton and any other kit, with dimensions as loaded.
2. Your legal basis: the state exception you rely on, for possession and for distribution, and the operating organisation.
3. Funding split: which funder pays for which product, so dispense reports can be separated.
4. Access model and limits: open, ZIP, code or card; units per vend; units per person per period.
5. Questions, if any: what you will ask, on the phone or on the touchscreen, and the rule that nobody is refused for skipping.
6. Instructions: panel text, QR destination, languages and whether you want a screen for video.
7. Site: indoor or sheltered, wall type, power and network, hours of access, and temperature if naloxone is stocked.

Hardware starts with the compact wall-mount machine at about US$800–1,500 per unit; floor-standing models start from US$1,200 (BG10X10). On a published free-vend project with a code and monthly quota, the software build was US$11,000 plus about US$200 a month. The breakdown is in harm reduction vending machine cost and the vending machine cost guide. Hardware and software are designed in-house; we sell direct and, in some regions, through local distributors. On-site installation is optional and, in some regions, provided through a local distributor, who then handles warranty and service; our support is by email.

Where a test strip machine is the wrong answer

• Where strips are not lawful to possess or hand out. In Iowa, North Dakota, Texas and the US Virgin Islands there was no drug checking exception as of August 2025; settle the law before the hardware.
• Where the program needs to explain results in person. A drug-checking service with a spectrometer, or a staffed session, gives far more information than a strip; a machine can only link to it.
• Where the only money is HHS money. Since April 2026 it cannot buy the strips. A naloxone-only machine is fundable; strips need another source.
• Where nobody will restock and rotate lots. Lot-to-lot variation is a reason to know what is in the coil.

Frequently asked questions

Can you get fentanyl test strips from a vending machine?

Yes, in many US cities and counties. Public health vending machines run by health departments and harm reduction services stock fentanyl test strips, and often xylazine test strips, next to naloxone. Published examples include New York State’s MATTERS network, Baltimore City, Howard County in Maryland, Boston, New York City and a Cincinnati service. They are usually free. Some machines need no information at all; others ask for a ZIP code or a code issued after a short registration, which may be done by scanning a QR code on the machine.

Are fentanyl test strips legal?

In most US states, yes, at least for some people. The Legislative Analysis and Public Policy Association found that, as of August 2025, possessing or using fentanyl test strips was not potentially subject to drug paraphernalia penalties for at least some individuals in 47 states, the District of Columbia and four territories. Iowa, North Dakota, Texas and the US Virgin Islands had no exception for any drug checking equipment. In some states the exception depends on who holds the strips or how they are used, so check your state law before stocking a machine. This is a planning summary, not legal advice.

Can federal grant money pay for test strips in a vending machine?

Not HHS money, since 24 April 2026. A SAMHSA Dear Colleague letter of that date says no HHS funding may be used to buy or distribute fentanyl test strips or other substance test kits, including xylazine and medetomidine strips, intended for use by people using drugs. That reverses the April 2021 CDC and SAMHSA position that allowed it. Naloxone, sharps disposal kits and distribution mechanisms such as metal boxes for overdose reversal medicines remain fundable. Programs now buy strips with state, county, opioid settlement or private funds.

What can a fentanyl test strip not tell you?

How much fentanyl is present, and whether something else dangerous is there. A strip shows presence above a detection threshold, not strength. Laboratory testing has found that strips can miss carfentanil at concentrations that may be dangerous, that sensitivity varied between manufacturing lots, and that diphenhydramine, lidocaine, MDMA and methamphetamine can cause false positives. CDC says methamphetamine samples must be diluted to 1 mg or less per mL of water. A negative result is not a safety guarantee, so instructions should always pair strips with naloxone and not using alone.

Should test strips and naloxone be in the same machine?

Usually, yes. Nearly every published US program that vends test strips also vends naloxone, because a positive test is most useful when the person can act on it and a negative test does not rule out overdose. In New York State’s evaluation of 15 machines, monthly medians were 529 naloxone kits, 245 fentanyl test strip packages and 169 xylazine test strip packages. Putting both in one cabinet also lets the program keep naloxone in a federally fundable part of the budget while paying for strips from other sources.

How should test strips be packed for a vending machine?

As a pack that vends as one rigid unit, not loose single strips. New York State’s evaluation counts strips dispensed as packages, and a pack can carry printed instructions alongside the strips. Thin, floppy packs are harder to dispense reliably from a coil than a small carton or stiffened bag. Send the pack as it will be loaded so coil pitch can be set; on KioskForce compact wall-mount machines coil pitch is configurable per selection, from narrow coils of about 40 to 50 mm to wide coils of about 70 to 90 mm.

Do people actually use test strips from vending machines?

Published figures say yes. An outdoor machine in Ohio dispensed 10,155 fentanyl test strips and 3,360 naloxone doses in its first year, and 12% of the 637 people who registered had not used harm reduction services before. Two touchscreen machines in Pennsylvania dispensed 2,755 drug testing strips in a year. In New York State, nearly half of all items were dispensed outside business hours. Those are dispensing counts; whether people tested, and what they did with the result, needs separate follow-up.
