## TL;DR

Oregon's drug decriminalization law increased police engagement and overdose rates among people under community supervision, highlighting the need for better support and legal protections.

## Contribution

This study is the first to examine the impact of Oregon's partial drug decriminalization on individuals under community supervision.

## Key findings

- Community-supervised people who use drugs had higher rates of opioid-related overdose compared to those not under supervision.
- 82% of supervised individuals reported police stops in the past year.
- Supervised individuals were more likely to fear legal trouble for calling 911 during an overdose.

## Abstract

In 2020, the U.S. state of Oregon passed Measure 110 (M110), which aimed to address substance use disorder as a public health issue and reduce disparities in the criminal legal system by decriminalizing personal drug possession and increasing services. The impact of partial drug decriminalization on individuals under community supervision—whose release conditions often prohibit drug use and who M110 excluded—is understudied.

We used targeted sampling to recruit and survey people who use drugs (PWUD; N = 468) in eight Oregon counties in 2023. We compared PWUD under community supervision to those who were not to assess opioid-related overdose, naloxone access, and law enforcement engagement.

Compared to PWUD who were not under community supervision, those under supervision had higher prevalence of past year opioid-related overdose. There were no differences by naloxone access. Eighty-two percent (82%) of PWUD on community supervision were stopped by law enforcement in the past year. PWUD on community supervision were more likely than those not on community supervision to report in the past year being searched by law enforcement at least once (adjusted prevalence differences [APD]=0.33; 95% CI: 0.23, 0.43), spent time in jail at least once (APD=0.33; 95% CI: 0.23, 0.43), and to have concerns about getting into trouble if they called 911 for a drug-related health issue (APD=0.12; 95% CI: 0.00, 0.18).

Under M110, Oregon PWUD under community supervision experienced more police engagement and overdoses. Findings have implications for less police presence at overdose scenes, greater access to naloxone and support services, and protections under future decriminalization laws.

•Community-supervised PWUD had a high prevalence of past year overdose.•The majority of community-supervised PWUD (82%) reported high levels of past year police engagement.•Community-supervised PWUD had concerns about being sanctioned during drug decriminalization.•Community-supervised PWUD feared legal trouble regarding calling 911 for an overdose.
