There was a significant decline in low-level drug enforcement, as reflected by a reduction in arrests for drug possession near the OPCs of 82.7% (95% CI, \u221289.9% to \u221270.4%) and a reduction in their broader neighborhoods of 74.5% (95% CI, \u221287.0% to \u221250.0%). Significant declines in criminal court summonses issued in the immediate vicinity by 87.9% (95% CI, \u221291.9% to \u221281.9%) and in the neighborhoods around the OPCs by 59.7% (95% CI, \u221273.8% to \u221238.0%) were observed. Reductions in enforcement were consistent with the city government\u2019s support for the 2 OPCs, which may have resulted in a desire not to deter clients from using the sites by fear of arrest for drug possession.<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>In this difference-in-differences cohort study, the first 2 government-sanctioned OPCs in the US were not associated with significant changes in measures of crime or disorder. These observations suggest the expansion of OPCs can be managed without negative crime or disorder outcomes.<\/jats:p><\/jats:sec>","DOI":"10.1001\/jamanetworkopen.2023.42228","type":"journal-article","created":{"date-parts":[[2023,11,13]],"date-time":"2023-11-13T16:01:25Z","timestamp":1699891285000},"page":"e2342228","source":"Crossref","is-referenced-by-count":37,"title":["Overdose Prevention Centers, Crime, and Disorder in New York City"],"prefix":"10.1001","volume":"6","author":[{"given":"Aaron","family":"Chalfin","sequence":"first","affiliation":[{"name":"National Bureau of Economic Research, University of Pennsylvania, Philadelphia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brandon","family":"del Pozo","sequence":"additional","affiliation":[{"name":"Division of General Internal Medicine, Rhode Island Hospital, The Warren Alpert Medical School of Brown University, Providence"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Mitre-Becerril","sequence":"additional","affiliation":[{"name":"University of Connecticut School of Public Policy, Hartford"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10","published-online":{"date-parts":[[2023,11,13]]},"reference":[{"key":"zoi231224r2","doi-asserted-by":"publisher","first-page":"48","DOI":"10.1016\/j.drugalcdep.2014.10.012","article-title":"Supervised injection services: what has been demonstrated?
