Drug checking is an evidence-informed harm reduction tool that allows people to check what’s in their drugs. Point of care drug checking services can test a range of substances, including opioids, stimulants, and other psychoactive drugs such as MDMA. Available in overdose prevention sites, music festivals and other community settings, these services give people results in less than 10-minutes.

To better understand the impact of drug checking on drug using behaviours and its value as a harm reduction tool, an evaluation of drug checking services provided at community organizations and events is being conducted.


This study intends to evaluate the point of care drug checking intervention currently being offered at select supervised consumption sites, overdose prevention sites, and other health authority-sanctioned sites in BC through a mixed-methods approach.

Specifically, this study aims to assess the performance of two point-of-care drug checking technologies - the Fourier-transform infrared spectroscopy - in the context of the overdose epidemic. An overview of technologies is available here: https://drugcheckingbc.ca/what-is-drug-checking/overview-of-technologies.

Additionally, the objectives of the study are to generate knowledge on the feasibility, uptake, and behavioural modifications that result from drug checking for the purposes of refining and informing future interventions, and learn about the accuracy of the point-of-care technologies.


We wish to thank the following partners and collaborators for their ongoing commitment to drug checking services in BC and Canada and for their support of this evaluation:

  • ASK Wellness
  • Drug Overdose and Alert Partnership
  • Fraser Health
  • Get Your Drugs Tested
  • Health Canada Drug Analysis Service
  • Interior Health
  • The International Centre for Science in Drug Policy
  • Insite
