SEATTLE, Wash. — Amid an opioid crisis with no end in sight, experts say a new opioid that’s even stronger than fentanyl is showing up on Seattle streets.

KOMO reports carfentanil is 100 times stronger than the synthetic opioid fentanyl, which has been blamed in a number of overdose deaths in Western Washington.

Carfentanil is 10,000 times stronger than morphine, and the state crime lab has detected it mixed with other drugs in a syringe found in a homeless camp in Seattle.

The DEA says its s drug that’s used on large animals and is very dangerous.

Public Health Seattle & King County says in a blog post that anyone who uses illicit drugs should never use alone and should always have the over-dose reversal drug nalaxone on hand.
