Trend Reports
The CFSRE is developing quarterly trend reports associated with NPS occurrence in the United States. These trend reports are intended to provide near real-time information regarding NPS prevalence, positivity, and turnover. Testing was performed using toxicology samples and drug materials. The CFSRE receives funding from the National Institute of Justice (NIJ) of the Department of Justice (DOJ) to continue development of this initiative.

Year in Review
Since 2018, NPS Discovery has reported 154 newly discovered NPS in the United States (Figure 1). NPS opioids remain the largest subclass (Figure 2). In 2023, NPS Discovery reported the discovery of 17 NPS for the first time.

Figure 2: Breakdown by subclass of newly discovered NPS, 2018-2023.
Since 2018, NPS Discovery has identified 240 NPS in forensic samples (Figure 3). NPS opioids, stimulants, and cannabinoids represent the largest subclasses observed. In 2023, 79 total NPS were detected (Figure 4).

Figure 4: Individual NPS detected each year, cumulative since 2018.
In 2023, NPS Discovery observed more than 3,600 total NPS detections within examined sample populations (Figure 5), a portion of more than 15,000 total NPS detections since our program launched in 2018 (Figure 6).
