Researchers find opioids, illicit drugs in Alberta wastewater samples

Researchers say the amount of opioids and other illicit drugs found in a monitoring of Alberta wastewater jumped in June.

Researchers say the amount of opioids and other illicit drugs found in a monitoring of Alberta wastewater jumped in June.

Wastewater testing is done weekly at six sites throughout the province as part of a pilot study funded by the Mathison Centre for Mental Health Research and Education at the Cumming School of Medicine and the Calgary Health Foundation that ends this fall.

There was four times the amount of carfentanil present in wastewater in June compared to earlier in the year, said Dr. Monty Ghosh, an internist, addictions specialist and assistant professor at the University of Calgary and University of Alberta.

“I don’t think people were aware of what was in the drug supply,” he said in an interview Wednesday.

“Our hypothesis, and we can’t confirm this of course, is that it was … a new cocktail of carfentanil, benzos and xylazine that might have come into the drug supply. We hadn’t seen this sort of this super concoction before.”

Studies have shown carfentanil to be 10,000 times more potent than morphine, 4,000 times more potent that heroin and 100 times more potent than fentanyl. It’s a synthetic opioid normally used in veterinary medicine to tranquilize large animals.

Ghosh said he’s saddened by the data, but not surprised. He said the subject of addictions is personal for him.

“I’ve lost so many patients to the drug poisoning crisis and there are people I knew who had worked in this field – peers, people with experience- who also lost their lives to this,” Ghosh said.
