Decriminalization of Drug Paraphernalia: Reviewing Evidence of Syringe Services Programs and its Intersection with the Law
Write-up by IRIS team member: Yali Deng
Syringe Services Programs (SSP) are community-based prevention initiatives designed to increase access to harm reduction services for people who use or inject drugs. The services often include access to sterile syringes, disposal of used injection equipment, testing, vaccination, linkage to treatment for infectious diseases, and linkage to treatment for substance use disorder (CDC, 2024). Decades of research indicate that SSPs are a safe, effective, and cost-saving method to reduce transmission of infectious diseases and improve health among people who use or inject drugs (CDC, 2024). These studies have also demonstrated that SSPs do not increase illegal drug use or crime (HIV.gov, 2026). SSPs are one proven practice within the harm reduction umbrella, an evidence-based approach that lowers health risks of people who use drugs, while providing pathways towards enhanced well-being (Salisbury-Afshar et al., 2024).
​
To support effective implementation of SSP, decriminalizing the possession drug paraphernalia is one way to reduce barriers to vital harm reduction services (Davis et al., 2019). In the current Maryland General Assembly (MD GA) session, SB327/HB0551 were cross-filed bills proposed that would repeal current criminal law which prohibits and penalizes possession and distribution of drug and controlled paraphernalia. Such decriminalization was attempted in the 2021 MD GA through SB420. While this bill was approved in both chambers, Governor Hogan (2021) vetoed the bill. Legislation was updated and signed into law in 2024 with HB0260/SB1009, which altered certain penalties for using or possessing drug paraphernalia with intent to sell, deliver or use. The current bills SB327/HB0551 would repeal current prohibitions from Maryland’s criminal law. Please see below for summaries of two relevant research articles, which speak to the effectiveness of SSPs and the value of removing barriers to vital harm reduction services.
In this research corner, we present two complementary articles. The first is a comprehensive systematic review conducted by the U.S Department of Veterans Affairs Evidence Synthesis Program to assess benefits and potential harms of SSP. The second is a mixed-methods evaluation study that examined a community-based syringe access program in Southern Appalachia. This study author identified broader themes from program staff and consumer perspectives about how punitive law enforcement and healthcare policies present barriers for harm reduction service utilization and overdose prevention.

"Effectiveness of syringe services programs: A systematic review"

To assess the benefits and potential harms of SSP, report authors reviewed 399 potentially relevant articles that were published before March 2023. They relied on a 2022 systematic review of the effectiveness of SSPs on HIV and HCV transmission, as well as injection risk behaviors. They prioritized synthesis of 48 primary studies on outcomes including injection frequency, naloxone distribution and overdose education, linkage to substance use treatment and utilization of treatment services, syringe disposal practices, and neighborhood crime rates. Most studies were conducted in large U.S. cities, particularly Baltimore, with some conducted in other countries. Most studies were conducted before the era of increased illicit synthetic opioids.
​
This review found sufficient evidence that SSPs are effective in preventing HIV transmission and reducing injection risk behaviors such as syringe sharing and re-use, while also potentially preventing Hepatitis C transmission. Importantly, the vast majority of evidence showed that SSP use does not increase injection frequency, unsafe syringe disposal, or neighborhood crime rates. In addition, SSPs serve as essential gateways to substance use treatment and overdose prevention. Most studies in this review indicate that SSP use was associated with increased use of treatment services, higher rates of carrying naloxone, and receiving overdose education. Preliminary evidence also showed that coordinated or co-located SSPs and opioid use disorder treatment have improved outcomes in the reduction of HCV transmission and needle sharing compared to either program alone.

This systematic review organized the evidence by each outcome and included a summary table of all included primary studies (e.g., citation, location, study design, sample size and results). Our readers can use this review to locate a specific article of interest.

“When people who use drugs can’t differentiate between medical care and cops, it’s a problem.” Compounding risks of law enforcement harassment & punitive healthcare policies
Ostrach, B., Hixon, V. & Bryce, A. (2024). “When people who use drugs can’t differentiate between medical care and cops, it’s a problem.” Compounding risks of law enforcement harassment & punitive healthcare policies. Health Justice, 12(3). https://doi.org/10.1186/s40352-023-00256-3
This mixed methods study evaluates a syringe access program in a mostly urban Southern Appalachian county where the Syringe Access Program (SAP) operated at multiple sites, including a public housing area and a local business. Data were collected from 2019 to 2021, including secondary program data and primary data, including informal interviews with 10 SAP participants, semi-structured interviews and focus groups with 3 SAP staff, and participant-observation at three outreach sites. The current review focuses on qualitative findings and omits program utilization results, based on the relevance of each to the bill and current research corner.
​
The study indicates that SAP served approximately 1900 participants during the study period. SAP staff reported that the majority of participants had a history of justice involvement, and the most common arrest was for possession of drug paraphernalia because local law enforcement often disregarded a limited immunity clause in the North Carolina syringe exchange law. This law provides immunity from arrest for possession of injection supplies, including used syringes, if the person presents a state-registered SSP participant card.
One of the major study themes that resulted from qualitative analysis was that law enforcement presented barriers to overdose prevention. One participant reported that he called 911 after someone in his car overdosed, but was arrested for paraphernalia possession despite disclosing the syringes in his car and presenting a valid SAP participation card. The case was dropped after he went to court. However, this experience has made him avoid calling 911 in the event of an overdose. Another participant also reported that fear of arrest deterred them from using emergency services because “police come first [before EMS]”. One participant stated, “I would be more likely to call 911 [for an overdose] if I hadn’t been cuffed, searched, and charged after doing so.”
Increased law enforcement presence near SAP outreach sites also deterred some participants from accessing harm reduction supplies and services. Participants reported that being stopped by law enforcement repeatedly made it harder to pick up overdose and infection prevention supplies from the SAP. SAP staff estimated that local law enforcement ignored SAP participants’ cards “about 40% of the time”, which should have provided legal immunity.
Based on the findings, authors recommended increased training for law enforcement on relevant public health laws. They further recommended expanding legal immunity beyond syringes to include all harm reduction supplies including snorting or smoking equipment, which may have greater potential to reduce overdose deaths. Authors note that since non-injection supplies were more commonly used by non-White SAP participants, and these residents were disproportionately targeted by law enforcement, that expanding these protections would help increase service access and support improved health outcomes for diverse populations. Overall, authors findings were consistent with the broader literature on this topic – that punitive policies and enforcement around drug paraphernalia act as deterrents to care-seeking and harm reduction services, which in turn create barriers to vital disease and overdose prevention among people who use drugs.
Conclusion
These two articles together provide compelling evidence for policies that protect harm reduction services. The VA systematic review demonstrates the benefits of SSPs in preventing risky injection behaviors and HIV and Hepatitis C transmission and facilitating connections to overdose education and substance use treatment. The mostly urban Southern Appalachia study reveals that real-world legal and law enforcement barriers can limit the access and effectiveness of these evidence-based interventions. To maximize the benefit of harm reduction services, it is important to provide legal protections for people to access these vital programs safely.
