Interior Health has issued a region-wide drug alert after samples of opioids, commonly known as “down,” were found to contain a highly toxic and unpredictable mix of substances.

The alert, dated February 11, 2026, warns of a very high risk of overdose from the contaminated supply. The substance, which appears as light purple chunks or pebbles, was found to contain carfentanil, medetomidine, fluorofentanyl, desalkylgabapentin, and multiple benzodiazepines, including ethylbromazolam, phenazolam, and bromazolam.

Health officials are highlighting the severe risks associated with this combination. Medetomidine, a potent sedative, can dangerously lower breathing and heart rate. When mixed with opioids and benzodiazepines, it can cause prolonged sedation, significantly increasing the chance of a fatal overdose.

Due to the extreme and unpredictable risk, Interior Health is strongly advising anyone who uses drugs to have them checked before consumption.

Harm reduction practices are crucial:

• Carry and know how to use naloxone.
• Use at a supervised consumption or overdose prevention site if possible.
• Never use alone.
• Start with a small amount and go slowly.

Drug checking services are available throughout the Interior to help identify the substances in a sample.
