The lethal mixture of xylazine and fentanyl, also known as Tranq dope, may sound unfamiliar to many, but its impact is harming people who use drugs nationwide. Xylazine, approved by the U.S. Food and Drug Administration for veterinary use as a sedative, has become a major component in the illicit drug trade. When consumed by humans, xylazine causes […]

For the last 20 years or so, the U.S. has seen a significant increase in opioid and drug overdoses overall. And while there was a slight leveling before the pandemic, “we’ve seen huge increases since COVID-19,” said Margaret Lowenstein, an LDI Senior Fellow, addiction medicine physician, and an Assistant Professor of Medicine at the Perelman School of […]

The Center for Health Economics of Treatment Interventions for Substance Use Disorder, HCV, and HIV (CHERISH) is proud to welcome Margaret Lowenstein, assistant professor at the Perelman School of Medicine and senior fellow at the Leonard Davis Institute of Health Economics (LDI) at the University of Pennsylvania, as the new co-director of the Dissemination and […]

Overdose deaths continue to be a national tragedy. More than 800,000 Americans died from an overdose between 1999-2019, and the annual rate of overdoses has increased dramatically during the pandemic, according to the latest data from the Centers for Disease Control and Prevention. Roughly 7 in 10 current overdose deaths involve opioids, which means that […]

From April 2020 through April 2021, there were 100,300 drug overdose deaths across the country according to the CDC — a 28.5% increase over the previous year. Some 75% of these were opioid-related overdoses that killed an average of nine users an hour around the clock throughout the year. Looking forward, the just-published Stanford-Lancet Commission on […]

If you want to reform state laws to require detox facilities to include medications like buprenorphine and methadone in their treatments, you should start by changing the “hearts and minds” of those who oppose it, Rebekah Gee, MD, MPH, MHSPR, told the January 14, 2022 Penn LDI/CHERISH Virtual Conference at the University of Pennsylvania. Keynoting a gathering organized […]

In November 2020, Oregonians voted to pass Measure 110, a ballot initiative that decriminalizes the possession of small amounts of all drugs and increases access to low-barrier substance use disorder treatment and harm reduction services. Led by the Drug Policy Alliance, the ballot measure is a historic step forward to address drug-related arrests that disproportionally impact low-income and people of […]

Overdose deaths have reached unprecedented levels in the U.S., despite effective medications to treat opioid use disorders (OUDs). Because the regulatory and administrative barriers to treatment are high, only about 11% of people with OUD receive effective medications, which include buprenorphine, methadone, and naltrexone. In response, clinicians and advocates have looked to a “low-threshold” approach […]

In a new study in the American Journal of Emergency Medicine, my colleagues and I estimate the number and distribution of emergency visits for opioid use disorder (OUD) across the country. We found that nearly 2/3 of all emergency visits for OUD occurred in 25% of EDs nationwide. Why is this important? Patients with OUD come to the […]

In the summer of 2021, the National Institute on Drug Abuse (NIDA) awarded Bruce R. Schackman, CHERISH director and Saul P.
