Do Drug Consumption Rooms Reduce Drug-Related Hospitalizations? Evidence from Switzerland
Using a difference-in-differences approach on Swiss data from 1998 to 2022, this study finds that the opening of drug consumption rooms reduces drug-related hospitalization rates by approximately 35% within a 5 km radius, primarily by converting fatal overdoses into non-fatal hospitalizations and lowering mental disorder admissions.

Every year, millions of people around the world struggle with addiction, a condition that carries severe risks for both individual health and public safety. When people use illicit drugs, particularly through injection, they face dangers ranging from fatal overdoses to life-threatening infections like HIV and hepatitis. In response to these crises, many cities have established supervised facilities known as drug consumption rooms. These are not treatment centers where people are forced to stop using; rather, they are hygienic spaces where individuals can use drugs they have already obtained under the watch of medical staff. The goal is harm reduction: providing clean equipment, immediate help if an overdose occurs, and a bridge to other health services, all while keeping drug use out of public streets. For decades, policymakers and public health officials have debated whether these rooms actually improve health outcomes or simply enable drug use. The question remains urgent: do these facilities save lives and reduce the burden on hospitals, or do they create new problems?
A new study by Ana Armendariz, a researcher at the University of St. Gallen in Switzerland, offers a clear answer by looking at real-world data from across the country. Switzerland holds a unique place in this story, as it was the first nation to open a drug consumption room, doing so in the city of Bern in 1986. Over the following decades, more facilities opened in various cities, creating a natural experiment where researchers could compare areas with these rooms to those without them. Armendariz analyzed a massive database containing records of every hospital admission in Switzerland from 1998 to 2022. By tracking exactly when and where these rooms opened, and comparing the health records of people living nearby against those living further away, she was able to isolate the specific impact of the facilities on hospital visits.
The findings are striking. The study shows that opening a drug consumption room leads to a significant drop in drug-related hospitalizations for people living within five kilometers of the facility. Specifically, the rate of these hospital visits falls by roughly 35 percent in the years following the opening. This reduction is not just a small statistical blip; it is a substantial shift in public health outcomes. The data reveals that the most dramatic change happens with fatal events. Hospitalizations that would have ended in death drop by about 35 percent. At the same time, the number of hospital visits for non-fatal drug poisonings rises by a similar amount. This pattern suggests that the rooms are working exactly as intended: when a person overdoses inside the facility, staff intervene immediately, turning what would have been a fatal event outside into a survivable medical emergency inside a hospital. The room acts as a safety net, catching people before they fall to their deaths.
The study also looked at other health issues linked to drug use, such as mental health disorders and infectious diseases. Hospitalizations for mental and behavioral disorders related to drug use declined by about 32 percent. For infectious diseases like hepatitis, the data shows a slower but steady improvement, with hospital visits dropping gradually over several years after a room opens. This delay makes sense, as the benefits of using clean needles take time to prevent infections that might lead to hospitalization later. The results for HIV were less clear, with the data not showing a definitive change, likely because the number of cases is smaller and harder to track with precision. However, the overall picture is one of success: the facilities are converting potentially deadly situations into manageable medical events and reducing the overall strain on the hospital system.
One might wonder if these rooms simply move the problem elsewhere or encourage more drug use, but the evidence from this study points in the opposite direction. The reduction in fatal events and the rise in non-fatal, treatable overdoses indicate that the rooms are effectively saving lives. The study confirms that these facilities serve as a critical component of public health strategy, offering a practical solution to a deadly problem. By providing a safe space for consumption, Switzerland has demonstrated that it is possible to reduce the most severe consequences of drug addiction without requiring immediate abstinence, turning a public health crisis into a manageable medical challenge.
