Fentanyl Warning

For the first time in Multnomah County, pure fentanyl was found in fake black tar heroin.

The Oregon State Crime Lab tested what looks like black tar heroin. Results showed no heroin, but was positive for fentanyl.

Seized fentanyl that looks like heroin

This substance was involved in at least one accidental fatal overdose in early April 2019

If you or someone you know used heroin:

  • Know your tolerance - Even if you have a high tolerance, you can still overdose. Tolerance levels drop rapidly during any break in use.
  • Go slow - Always do a test shot when using a new supply. Always go slow, especially after any break from using (jail, detox, etc.).
  • Be careful when mixing drugs - Opioids, alcohol, and benzodiazepines (Xanax, valium, etc.) all slow down breathing. Mixing these increases overdose risk.
  • Have an overdose plan - Make sure someone can get to you when you use. It is safest to only use when you are with someone else.
  • Carry naloxone - Naloxone reverses the effects of opioid overdose. It is legal to carry and administer naloxone in Oregon.
  • Ask about fentanyl test strips - Some exchange sites have test strips available, ask staff. Knowing what is in your drugs can help you decide how to use safely.
