BACKGROUND: The North American overdose crisis has continued at unprecedented rates with more than 100,000 overdose deaths estimated to have occurred in the United States in 2022. Regional variations in overdose rates signify differences in local drug supplies. State-level drug supply surveillance systems have been limited in their ability to document and communicate the rapidly changing drug supplies which can hinder harm reduction efforts at the community level. We sought to address by piloting a two-year, community-engaged local drug supply surveillance program in Rhode Island (RI).
METHODS: The first set of samples (n = 125) were collected from May 2022 to January 2023 across RI and included used paraphernalia (e.g., cookers), refuse (e.g., baggies), and product. Samples were tested using comprehensive toxicology testing approaches via liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS). Results were disseminated to participants and the broader public across platforms.
RESULTS: Fentanyl was detected in 67.2% of all samples tested. 39.2% (n = 49) of samples were expected to be fentanyl. Xylazine was detected in 41.6% of all samples-always in combination with fentanyl-and no samples were expected to contain xylazine. In expected stimulant samples (n = 39), 10% contained fentanyl and/or analogues as major substances and 30.8% contained trace amounts of fentanyl and/or analogues. In expected stimulant samples, 15.4% contained xylazine with fentanyl. No opioids or benzodiazepines were detected in expected hallucinogen or dissociative samples (n = 7). In expected benzodiazepine samples (n = 8), no opioids were detected.
CONCLUSIONS: Our results describe part of the local drug supply in Rhode Island, including a presence of NPS and adulterants (e.g., designer benzodiazepines, xylazine). Importantly, our findings underscore the feasibility of developing a community-driven drug supply surveillance database. Expanding drug supply surveillance initiatives is imperative for improving the health and safety of people who use drugs and informing public health approaches to addressing the overdose crisis.
