The Rapid Response™ Xylazine Test Strip (Liquid / Powder) is a rapid visual immunoassay for the qualitative, presumptive detection of xylazine in suspicious substances (liquids or powders) at the cut-off concentration of 1000 ng/mL.
Xylazine is a non-opioid tranquilizer used as a sedative, analgesic, and muscle relaxant in animals such as horses and cattle[1],[3]. In recent years, xylazine has emerged as an adulterant in recreational drugs such as heroin[2]. Combining xylazine with other drugs that cause central nervous system depression compounds the sedative effects and can increase the risk of overdose and death[2].
* A negative result can be interpreted as soon as both the test (T) and control (C) lines appear. A positive result can be interpreted once the control line has appeared and the background has cleared to white, typically by 60 seconds. Do not read results after 10 minutes.
Philadelphia Department of Public Health found the BTNX Inc. Xylazine Test Strip’s performance to be deemed acceptable for drug checking purposes. Read the article here.

The Rapid Response™ Xylazine Test Strip Kit (Liquid / Powder) is a rapid visual immunoassay for the qualitative, presumptive detection of xylazine in suspicious substances (liquids or powders) at the cut-off concentration of 1000 ng/mL. The kit contains additional materials required to test liquid or powder samples for the presence of xylazine, including: strips, collection swabs, and prefilled liquid buffer tubes. For forensic use only. Not an IVD.
Xylazine (colloquially known as tranq/ tranq dope) is a non-opioid tranquilizer used as a sedative, analgesic, and muscle relaxant used in veterinary medicine for animals including horse and cattle[1],[3]. Recently, it has commonly been encountered in the recreational drug supply, most commonly in opioid “dope” (e.g., fentanyl, heroin)[2]. Combining xylazine with other drugs that cause central nervous system depression compounds the sedative effects and can increase the risk of overdose and death[2].

Benzodiazepines 300 related compounds
What are Benzos and what are they intended for in a medical setting?
Benzodiazepines are a controlled class of molecules which promote the binding of gamma-aminobutyric acid (GABA) to GABAA receptors in the body, resulting in reduced excitability of neurons and producing a calming effect on the brain.1 Due to the effects of benzodiazepines, they have been prescribed for a variety of uses, including to treat anxiety, insomnia, and muscle spasms.1,2 Xanax (alprazolam), Valium (diazepam), Halcion (triazolam), Ativan (lorazepam), and Klonopin (clonazepam) are currently among the most commonly prescribed pharmaceutical benzodiazepines.3
What drugs are adulterated with benzos?
Benzodiazepines, like many other drugs, are misused, being sourced through both legal avenues as well as through the illicit drug supply.2,3 When sourced through legal avenues, users can be assured of drug purity and contents. However, illicit benzodiazepines are rarely pure, and often co-occur with other drug substances.4-8 The most common and dangerous type of drugs co-identified with benzodiazepines are opioids, which include drugs like fentanyl and heroin.7,8 In fact, recent drug checking reports from Toronto and British Columbia have identified how prevalently the two drug classes are found together, with approximately 45-50% of all drugs expected to be of opioid origin also containing at least one benzodiazepine.7,9
What are the risks/outcomes of unknowingly taking benzos?
Benzodiazepine toxicity is often associated with central nervous system depression, such as slurred speech and loss of coordination; it is rare for vital processes, like respiration, to be severely depressed in cases of mono-substance benzodiazepine toxicity.9 However, benzodiazepines are often used with other drugs,7,8 such as opioids, and presents a heightened toxic effect in these situations. In such cases, benzodiazepines have been observed to significantly compound respiratory depression, a leading cause of overdose.2,9

Nitazene
Nitazenes are a class of synthetic drugs that have gained attention in the United States and other countries in recent years. The prevalence of nitazenes in the illegal drug supply has been on the rise since 2019. Recent evidence suggests nitazenes may be more potent than fentanyl and may require a higher dose of naloxone in case of overdose.1 In the same study, several individuals who overdosed on nitazenes were unaware that their drugs contained it.1
