An experimental decriminalization program in the Canadian province of British Columbia, aimed at reducing overdose fatalities, has not demonstrably lowered the death toll, according to a new study published in the Canadian Medical Association Journal. The pilot scheme, which began in January 2023, allowed individuals found possessing less than 2.5 grams of hard drugs, including fentanyl, heroin, methamphetamine, and crack cocaine, to be directed to social support services instead of facing arrest or charges.
The study analyzed police-reported drug possession incidents and health outcome data from August 2020 to March 2025. Researchers found that while drug decriminalization was associated with a substantial decrease in police-reported drug possession incidents in British Columbia—a 39 percent drop—it did not lead to corresponding changes in drug toxicity deaths or hospitalizations when compared to other regions in Canada. For instance, while overdose deaths fell by 19 percent in British Columbia during the study period, they also decreased by 25 percent in Ontario over the same timeframe.
"Drug decriminalization and recriminalization in BC were associated with substantial changes in police-reported drug possession incidents, but no corresponding changes in drug toxicity deaths or hospitalizations when compared to other regions in Canada," the report states. "The findings suggest decriminalization is effective at reducing drug possession incidents but is insufficient in isolation to affect health outcomes."
Dr. Daniel Myran, one of the study's authors, noted that the observed health benefits in British Columbia were not unique to the province. "I do think that the premise of 'we're going to see these very large health benefits related to acute overdoses' has not been borne out by the data we're presenting here," he told the National Post.
When the pilot program was initiated, provincial health officer Dr. Bonnie Henry described it as "an important step to save lives as we continue to tackle the toxic drug crisis in BC." She added that the exemption would help reduce the stigma associated with substance use, which often leads individuals to use drugs alone, and facilitate connections to health and social supports.
However, the pilot was officially abandoned in January 2026. Josie Osborne, who served as BC's health minister, acknowledged that the program had not yielded the anticipated results. She also noted the difficulty in attributing specific changes or increases directly to decriminalization.
Partially in response to public concerns about increased drug use in public spaces, the decriminalization policy was scaled back. In May 2024, possession of any amount of drugs in public places was criminalized again, although possession of less than 2.5 grams by adults remained legal in private settings and at overdose prevention sites.
Over the five-year study period, researchers documented 97,630 instances of police encounters for drug possession across Canada. These included 75,485 for drug trafficking, 161,278 opioid-related hospitalizations, 113,747 stimulant-related hospitalizations, and 29,730 drug toxicity deaths in British Columbia, Ontario, and Alberta. Following the partial recriminalization in public areas, British Columbia saw a 68 percent increase in drug possession incidents. The research indicated that after recriminalization, British Columbia's trends in opioid-related hospitalizations and deaths did not significantly differ from other provinces.
British Columbia is situated near Washington state, where similar legislative approaches have also faced challenges. According to the latest available data from the Centers for Disease Control, Washington state, along with West Virginia, New Mexico, and Alaska, recorded the highest number of overdose deaths per capita among U.S. states in 2024.
