Prevalence of fentanyl in methamphetamine and cocaine samples collected by community-based drug checking services

Recommended interventions include expanding community-based drug checking, naloxone and fentanyl test strip distribution for stimulant users, and supervised drug consumption sites. New strategies to dampen variability in street drug composition are needed to reduce inadvertent fentanyl exposure.
