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.
Higher levels of opioids and meth found in Vancouver waste water: StatsCan
Metro Vancouver has higher-than-average levels of opioids and methamphetamine in its waste-water system compared with other Canadian cities, according to a new Statistics Canada study analyzing cannabis and drug use in the country based on what Canadians flush down their toilets. In contrast, Vancouver reported less-than-average levels of cannabis in sewage, casting doubt on the city’s reputation as Canada’s cannabis capital.
