To understand why safer supply and other harm-reduction measures exist, you have to start with the product on the street. Over the past decade, the unregulated drug supply in British Columbia and much of Canada became unpredictable and lethal. This article explains how, using the most recent official numbers.

The scale of the crisis

BC declared a public health emergency over overdoses in 2016. According to BC Coroners Service data reported in early 2026, 1,826 people died of unregulated drug toxicity in the province in 2025. That is about 21% fewer than in 2024, when the figure was 2,315, and it is the first year since 2020 with fewer than 2,000 deaths. Reports put the cumulative total since the emergency was declared at more than 18,000 people.

A decline is welcome, and nobody can say with certainty what caused it. Researchers have pointed to many possible contributors, including naloxone distribution, expanded treatment, changes in the supply, and a smaller pool of people at risk after years of loss. None of them has been shown to be the sole explanation. And 1,826 deaths still works out to roughly five a day in the first half of the year. Unregulated drug deaths remain the largest single source of unnatural death in BC, ahead of suicide, motor vehicle incidents, and homicide.

What is in the supply

Fentanyl is a synthetic opioid many times more potent than heroin. It is cheap to produce and easy to smuggle in small quantities, which is why it replaced much of the heroin market. Coroner reporting from 2025 found fentanyl or its analogues in a large majority of deaths, with figures ranging from about 70% to 84% depending on the reporting period and which cases had toxicology results available. Cocaine (about 52%) and methamphetamine (about 51%) were also commonly detected, which shows how often deaths involve several substances at once.

Coroners also noted an increase in deaths in which carfentanil was detected. Carfentanil is an extremely potent opioid, and even tiny amounts of it in a mixture can be deadly.

The central problem is inconsistency. Illicit drugs are not manufactured with quality control. Fentanyl can be unevenly distributed through a batch, so that one dose has little and the next has a lethal amount. A person who uses the same source every day can still get a very different product from one purchase to the next.

Who is dying

The pattern in 2025 data is consistent with earlier years:

• About 69% of those who died were between 30 and 59.
• About 77% to 78% were male.
• The highest numbers were in the Fraser and Vancouver Coastal health authorities, which together accounted for more than half of deaths. The highest per-capita rates were in Northern and Interior regions.
• Youth deaths (under 19) were relatively few but rose, from 21 in 2024 to 26 in 2025.

How people are using

Two details in the coroners’ data have shaped harm-reduction work. First, smoking has become the most common method of consumption, involved in about 64% of deaths where the information was available. That matters because most overdose-prevention infrastructure was built around injection. Second, about 48% of deaths occurred in private residences, compared with about 21% outdoors. People who use alone at home have no one to call for help or give naloxone.

This is why many harm-reduction measures focus on the moment of use: services that support inhalation, phone-in or app-based services that connect a person with someone who can send help, and encouragement not to use alone.

Why fentanyl changed the logic of risk

Before fentanyl, the main risks of opioid use were dependency, infection from injecting, and occasional overdoses. With fentanyl, the margin between a dose that a person tolerates and one that kills has narrowed sharply. Even people with long experience can misjudge. Stimulant users who never intended to take opioids can be exposed through contaminated cocaine or methamphetamine, and that group is easy to overlook.

What reduces the risk right now

Public-health and harm-reduction organizations commonly recommend the following steps:

• Carry naloxone and know how to use it. It temporarily reverses opioid overdoses, though more than one dose may be needed with potent opioids.
• Do not use alone. Use with someone, use at a supervised site, or use an overdose-detection phone service.
• Check your drugs where drug-checking services exist. Fentanyl test strips are one option, though they have limits (see Article 6).
• Learn the signs of overdose and call emergency services.
• Seek treatment when ready. Opioid agonist treatment lowers mortality, and a clinician can discuss options.

For general harm-reduction guidance, organizations such as DanceSafe (dancesafe.org) and TripSit (tripsit.me) publish reliable information, and local health authorities list services by community.

The takeaway

The toxic drug supply is not a metaphor. It is a manufacturing and distribution problem: an unregulated product of unknown strength, taken often in private and often alone. Every policy in this series, from safer supply to drug checking to naloxone, is an attempt to reduce the risk that follows from that fact.
