LOS ANGELES (AP) — One person was in grave condition after possible exposure to the drug fentanyl at a Los Angeles hotel early Tuesday, authorities said.
Three other people appeared to be in stable and fair condition, Fire Department spokeswoman Margaret Stewart said.
The incident occurred before 7 a.m. at an Extended Stay America hotel in Woodland Hills.
The hotel room was closed off and a hazardous materials squad was summoned to investigate a powdered substance.
Fentanyl is a synthetic opioid pain reliever.
According to the Centers for Disease Control and Prevention, fentanyl is 50 to 100 times more potent than morphine.
Most recent cases of fentanyl-related harm involve illegally made fentanyl, according to the CDC.
The illegally made drug is often mixed with heroin and cocain
