What is Xylazine / Tranq Dope?

Xylazine, also known as “tranq,” “tranq dope,” and “zombie drug,” is a non-opioid veterinary tranquilizer being found in the U.S. illicit drug supply. Xylazine has become a popular cut for black market opioids, such as fentanyl and heroin. However, xylazine is a sedative, not an opioid, making it resistant to opioid reversal treatments, such as Narcan.

Xylazine causes strong drowsiness, amnesia, slowed breathing and heart rate, and low blood pressure. When cut with opioids, the combined sedation can increase the risk of overdose, drug-related injury, and even death. Frequent use of xylazine can cause severe ulcers, abscesses, necrosis, and other wounds to the skin, which may appear far from injection sites, and can also occur due to smoking, snorting, swallowing, and other means of ingestion.


Xylazine Test Strips Instructions

IMPORTANT: These Xylazine Test Strips should ONLY be used to test opioids. Please read these instructions carefully and dilute properly!

When using our Xylazine Test Strips, sample preparation is important. Any drug can produce false positives if over-concentrated (not enough water is used to dilute), or false negatives if not concentrated enough (too much water is used to dilute).

The proper dilution for any drug checking strip is initially determined by laboratory analyses, as well as relevant facts about the current status of the illicit drug supply, such as the average concentrations of various adulterants in specific drugs. Over time, field testing, supplemented by confirmatory lab analysis (like GC-MS) may change our understanding of the optimum dilution.

When properly diluted, our strips are capable of detecting even tiny, microgram levels of xylazine, and should not produce false positives even if the sample contains high concentrations of fentanyl, heroin, diphenhydramine, alprazolam, diazepam, etizolam, oxycodone, hydrocodone, or lidocaine.

Please refer to our instructions for the current optimum dilution ratios.
