'Alarming' new drug found in Ottawa's unregulated supply

Ottawa Public Health (OPH) and emergency responders are warning about a new drug that they say could lead to more overdoses in the city.

In a joint statement Thursday, OPH, Ottawa police and thecity'soverdose prevention and response taskforce issued an alert after the first sample of a drug called "N-pyrrolidino etonitazene"also known as "Pyro"was detectedthis week.

According to OPH, the drug belongs to a class of substances referred to as nitazene opioids, and is considered to be roughly 10 times more toxic than fentanyl and 1,000 to 1,500 times more toxic than morphine.

The drugwas found in counterfeit hydromorphone(Dilaudid) M8 tablets. The white tablets were three-sided and labelled with the letter M and the number8.

The drug was most recently confirmed to be involved in an overdose in 2022, according to OPH. There were 22 deaths in 2022 and 39 deaths in 2021 where Nitaznese were present.

Morgan Dalgleish, supervisor of OPH's harm reduction program,said nitazene opioids are not new, but this is the first time they've appeared in Ottawa's unregulated drug supply. He called the discovery "alarming."

"They've been around for about 60 years as a synthetic opiate created by scientists not to replace morphine, but to be an alternative to morphine," Dalgleish said.

"There has been a steady increase in toxicity in this drug supply, which has made things unpredictableand definitely unsafe."

High toxicity, higher risk

Dalgleishsaid other unregulated opioidsincludingoxycodone (OxyContin), hydrocodone and Percocethave been found to contain nitazenes in Ontario.

He added that because of Pyro's toxicity, the risk of overdosing is higher and greater doses of naloxone may be required to help someone experiencing an overdose.

"This really paints the importance of carrying naloxone in the first place," Dalgleishsaid.

OPH is reminding those who use drugs not to usealone and to carrynaloxone, which is available for free through various programs in the city. To be effective, arepeat dose of naloxoneis needed every two to threeminutes until the person responds or first responders arrive.

"The buddy system is absolutely safer than using alone. So, if you are using with someone else, please at least use one at a time before the other person does," Dalgleish said.

"If people are using alone, please tell someone before you do use."

There arecurrently threesupervised consumption sites operating in Ottawa.
