Observing from Afar: Continuous Pulse Oximetry for People Who Smoke Opioids to Prevent Overdose

Smoking has become the most common way that people take opioids in British Columbia. The proportion of overdose deaths from smoking unregulated drugs increased from 31% to 56% between 2016 and 2020.[1] Although smoking opioids is common, overdose prevention services do not have many tools to support people who smoke opioids.

Pulse oximeters check the amount of oxygen in people’s blood in real-time. Healthcare settings often use continuous pulse oximeters, which can be operated remotely. We wondered if overdose prevention services can also use continuous pulse oximeters to help people who smoke opioids.

In partnership with four overdose prevention services across British Columbia, we studied whether continuous pulse oximeters are effective at detecting overdoses, easy to use, and acceptable to staff and people who use opioids at these sites.

If you have questions, comments, or are adapting oximetry technology at your site, we'd be pleased to connect and to learn about your experiences. Feel free to email Dr. Moe at

Understanding Substance Use Patterns & Preferences: Informing Safe Supply and Safer Use Services

This study aims to gain an understanding of how and why people who use drugs use particular substances and modes of use as well as their Safe Supply needs and preferences, to identify opportunities and gaps in the design of Safe Supply frameworks and models. Consultation with people who use drugs ensures Safe Supply will be designed practically to increase accessibility, and better positions programs to anticipate and account for potential shifts in needs and preferences. To learn more about the project background see the overview below.

Good Samaritan Drug Overdose Act (GSDOA) Project

In May 2017, the Government of Canada introduced the Good Samaritan Drug Overdose Act (GSDOA). The act aims to ensure bystander response by providing legal protection for anyone who is at the scene of an overdose from simple possession (possession for personal use) of an illegal substance.

The GSDOA evaluation project aims to assess the implementation of the GSDOA and evaluate its effectiveness at increasing bystander response in the event of an overdose by assessing knowledge, attitudes, experiences and intentions regarding the GSDOA in British Columbia.

Concurrent Use and Transition to Methamphetamine among persons at risk of Overdose (CUT Meth OD)

There has been a big increase in the Methamphetamine (MA) use in British Columbia1.  Meth use has been associated with health problems and some people who use Meth choose to use it with other drugs like opioids. However, there is limited literature identifying the reasons for MA use on its own or with other substances.

This study, funded by CIHR, will help us understand, (1) why MA use has increased; (2) reasons for MA use with other drugs; (3) perceptions about the benefits and harms of MA use.

The findings from this study will help fill the knowledge gap to better understand the factors associated with MA use, and help to develop effective harm reduction interventions.

Communicating Drug Alerts (CDA) Project

British Columbia’s regional health authorities issue drug alerts to inform people who use substances about contaminated drugs in the community. Over the years, street drugs have become increasingly toxic which has only been worsened with the emergence of COVID-19. Drug markets have become gradually more volatile, resulting in unpredictable and increasingly toxic drug supplies and increasing rates of overdose-related deaths. We are looking to interview people who use substances to improve existing guidelines regarding drug alert communication. We are especially interested in hearing from youth, trades people, people who identify as GLBTQ2S+, and people who identify as South Asian, and how we can make drug alerts more relevant and accessible to these groups.

Media & Language: De-stigmatizing Language around Substance Use & Harm Reduction Reporting

Media contributes to stigmatizing substance use by using stereotypical and harmful images and words to describe people who use substances. These descriptions create a damaging discourse that substance use is a public burden driven by crime and deviance, rather than a public health concern. This project aims to de-stigmatize substance use and harm reduction reporting by encouraging journalists and media professionals to use person-first language and non-stigmatizing images in their reporting.

A rapid evidence literature review was performed and findings discussed by people with lived and living experience of substance use who shared their personal experiences of the impact of stigmatizing language and images in media. No Canadian reporting standards were identified. ​The report includes the review findings, perceptions of people with lived and living experience, and makes recommendations on how to reduce stigma in the media.
