Safety TipsCounterfeit "prescription" pills and unexpected adulterants (like fentanyl and xylazine) are widespread. Fentanyl is a potent synthetic opioid that has driven large increases in overdose deaths. Xylazine ("tranq") is a non-opioid veterinary sedative that does not respond to naloxone and increases risk of severe wounds and prolonged sedation. Treat unknown pills as potentially lethal.

A class of synthetic opioids called orphines (mostly cychlorphine), estimated at roughly 10x the potency of fentanyl, is rising in the illicit supply across 22 states, Minnesota included. Detections surged starting in late 2025 (JAMA Psychiatry, Oct 7 2026). Assume any pressed pill or powder could be far stronger than expected: start low, go slow, test everything, never use alone.
Medetomidine, a veterinary sedative nicknamed "rhino tranq," is showing up in Minnesota's fentanyl supply. It causes deep, prolonged sedation with dangerously slowed breathing and heart rate, and naloxone does not reverse its sedative effects. Withdrawal can be severe and may need hospital care. If someone is heavily sedated but breathing, stay with them, keep them safe, and call for help early.
Alerts change fast. When in doubt, test before you trust and carry naloxone every time.
FTS are a fast, low-cost tool to check for fentanyl in pills, powders, or residue. They can lower risk by informing choices, but they are not perfect.
Reagent color tests (Marquis, Mecke, Mandelin) can indicate some drug classes (MDMA, some opioids, certain stimulants) but cannot reliably detect fentanyl and can be fooled by carefully pressed counterfeits. Use reagents as one tool, not the only tool.
For blotter sold as LSD: an Ehrlich reagent test is the relevant check. And remember the street rule: a bitter or metallic tasting tab is not LSD, it may be an NBOMe compound, which has caused deaths. Our psychedelics guide covers fake acid in detail.
FTIR / laboratory & event-based checking (spectrometers) identify a broader range of substances and are the most informative option when available. Many harm-reduction programs and some festivals offer FTIR or GC-MS testing events.
No testing method is 100% accurate. Always use multiple harm reduction strategies together.
Do not assume safety. Consider not using the substance. If someone chooses to use, use a very small test dose, do not use alone, avoid mixing depressants (alcohol, benzodiazepines), and have naloxone and a sober person present.
Legal protections: Minnesota's Good Samaritan / overdose immunity laws protect callers from certain drug possession charges when they call for medical assistance during an overdose. See Minnesota statute: Minn. Stat. §604A.05.
