Canadian Drug and Substance Watch : New and emerging substances

Emergence timeline

The emergence timeline shows the first and subsequent detections of a new or emerging psychoactive substance for each data source. The timeline also tracks the substance over time and, where possible, by location.

For each data source, a substance is counted a maximum of once per month in each province or territory, regardless of how many individual samples it was detected in each month (we call this the number of monthly detections). This approach standardizes detections across data sources to indicate presence or absence of a substance in each data source and in each province or territory.

Filter by pharmacological class and substance from the dropdown menu. Hover over or tap the location or tiles of the timeline to display the number of monthly detections in that location and during that time. To breakdown the identifications by data source, filter by location.

Emergence timeline: Text description

The text description table data for the emergence timeline figure can be found in the psychoactive substances table below.

Notes

• Only provinces and territories with at least one substance identification have been included within the emergence timeline.
• Canada and online is the number of identifications across Canada, including those found via web monitoring.
• Wastewater counts and trends may be influenced by the number of wastewater collection sites reporting in a given time period.
• "Not available (N/A)" indicates no geographic information is available (for web monitoring data)
• "Previously identified" indicates substances that were identified before January 2023 in DAS samples
• "Not collected" indicates regions and time periods where no wastewater samples were collected
