Fentanyl and other opioids have been found in trace amounts in Canada’s surface water and drinking water. When people use these drugs, some is absorbed into the body and the rest ends up in the wastewater stream and subsequently in the environment.
While the concentrations are very low and scientists say there’s no cause for panic, they are concerned about how drinking water sources may ultimately be affected and what long-term effect low dosages may have on humans and wildlife.
