The US overdose crisis is driven by fentanyl, heroin, and prescription opioids. One evidence-based policy response has been to broaden naloxone distribution, but how much naloxone a community would need to reduce the incidence of fatal overdose is unclear. We aimed to estimate state-level US naloxone need in 2017 across three main naloxone access points (community-based programs, provider prescription, and pharmacy-initiated distribution) and by dominant opioid epidemic type (fentanyl, heroin, and prescription opioid).

Background: Drug checking uses analytical chemistry technologies to report on the composition of drugs from the unregulated market to reduce substance use-related risks, while additionally allowing for monitoring and reporting of the supply. In the context of an overdose crisis linked to fentanyl, we used drug checking data to examine variability within the illicit opioid supply.

Fueled by misinformation, fentanyl panic has harmed public health through complicating overdose rescue while rationalizing hyper-punitive criminal laws, wasteful expenditures, and proposals to curtail vital access to pain pharmacotherapy. To assess misinformation about health risk from casual contact with fentanyl, we characterize its diffusion and excess visibility in mainstream and social media.

In 2015, 33,091 persons in the United States died from an opioid-related drug overdose.The epidemic of opioid overdose deaths has led to expanding the use of naloxone in community settings by non–medically trained bystanders who are often people who use drugs (PWUD). Since 2013, illicitly manufactured fentanyl (IMF), fentanyl analogs, and other synthetic opioids have played an increasing role in overdose deaths in the United States. Illicitly manufactured fentanyl (IMF) prevalence has increased. However, there is uncertainty about naloxone dose(s) used by nonmedical bystanders to reverse opioid overdoses in the context of increasing IMF.

The current study examined the accuracy of sensory discernment strategies by measuring study participants’ descriptions of the last opioid injected and checked with a fentanyl test strip (FTS) by that test's positive/negative result. The primary objective was to determine associations between FTS results and descriptions of the illi it opioid's physical appearance and physiological effects.

Using data from 77 harm reduction programs in 25 US states, researchers found that 12-15% of powder methamphetamine and powder cocaine also contained fentanyl although the prevalence varied geographically. Prevalence of fentanyl in crystal methamphetamine and crack cocaine was lower. Heroin and xylazine were also found in unregulated stimulants. Xylazine reduced the ability to detect fentanyl.
