Morphine, methadone levels in Metro Vancouver wastewater Canada's highest

Levels of morphine and methadone in Metro Vancouver’s wastewater were Canada’s highest in 2019 and 2020, a reflection of high crime rates and heroin use, says a recent Statistics Canada report. However, codeine levels in B.C. wastewater dropped in 2020 — possibly due the cancellation of surgeries during the pandemic and changes to drug regulations in British Columbia. The study said morphine is produced as a metabolite when the human body consumes heroin and shows up in wastewater.
