Crystal Clear: Prevalence of fentanyl in methamphetamine and cocaine samples collected by community-based drug checking services
Year: 2023
Type: article
Study design: Observational Study
Abstract: Methods: We quantified prevalence of fentanyl in street methamphetamine and cocaine, stratified by crystalline texture, analyzing samples sent voluntarily to a public mail-in drug checking service (May 2021-June 2023). Samples from 77 harm reduction programs and clinics originated in 25 US states. Sample donors reported expected drug and physical descriptions. Substances were identified by gas chromatography-mass spectrometry . Negative binomial models were used to calculate fentanyl prevalence, adjusting for potential confounders related to sample selection. We also examined if xylazine modified donors’ expectations of fentanyl positivity.
