Trust, place, and polysubstance use shape the feasibility of community-based drug checking in the Southern United States: A mixed-methods implementation study
This mixed-methods study in Fulton County, Georgia, reveals that while community-based drug checking is urgently needed to address the volatile drug supply, its implementation is significantly hindered by institutional mistrust, reliance on known drug sources, and the complexities of polysubstance use, indicating that legal reforms and testing tools alone are insufficient without addressing these social and contextual barriers.

In the United States, the supply of illegal drugs has become dangerously unpredictable. It is no longer just about one substance; pills and powders are frequently mixed with powerful synthetic opioids like fentanyl and a veterinary tranquilizer called xylazine. This volatile mixture has led to a sharp rise in overdose deaths, particularly in the Southern United States. To combat this, public health experts have turned to a strategy called drug checking. This is a harm reduction practice where people who use drugs can test their substances before consuming them to see if they contain unexpected or deadly ingredients. The goal is simple: knowing what is in a drug allows a person to make a safer choice, such as using less, using a different method, or not using at all. While this approach has shown promise in other parts of the country, its success depends heavily on whether people trust the system enough to use it.
A new study conducted in Fulton County, Georgia, investigates why drug checking has not been widely adopted in the South, despite the clear danger of the current drug supply. Researchers worked directly with people who use drugs to understand the real-world barriers preventing them from testing their substances. They found that the issue is not simply a lack of tools or laws. Instead, the decision to test is shaped by a complex mix of trust in drug dealers, the fear of police surveillance, and the reality that people often use multiple substances at once. The study suggests that simply handing out test strips or changing the law is not enough; for drug checking to work, it must be built on relationships and environments where people feel safe and understood.
The research team, led by scholars from Emory University and community partners, conducted a detailed investigation in Fulton County, a region that has seen some of the highest overdose rates in the state. They recruited 164 people who use drugs from various settings, including syringe service programs, bars, music festivals, and informal housing where drugs are sold and used. The study used a mix of surveys and in-depth interviews to ask participants about their drug use habits, their trust in the people who sell them drugs, and their willingness to use drug checking services. The researchers also spoke with a smaller group of 16 participants in greater detail to understand the personal reasons behind their choices.
The findings revealed a striking contradiction. Nearly two-thirds of the people surveyed said they had never tested their drugs, even though most were aware of the risk of overdose. The primary reason for not testing was not ignorance or a lack of concern, but rather a deep-seated trust in their drug sources. Many participants reported that they knew their dealers or suppliers personally and believed they would not sell them a product laced with something deadly. For these individuals, the relationship with the seller felt like a more reliable safety check than a piece of paper or a digital app. One participant noted that they had a specific dealer they trusted because that person shared information about the purity of each batch. This reliance on personal trust meant that the perceived need for formal testing was low.
However, this trust in dealers existed alongside a profound distrust of institutions. When the researchers asked about using official drug checking services or mobile apps, participants expressed significant fear. They worried that providing a sample or using an app could lead to police surveillance, arrest, or the loss of their privacy. Even though Georgia recently passed a law making drug checking equipment legal, the participants did not believe that law enforcement would respect these protections. They feared that authorities might use the data to target them rather than help them. This fear was compounded by the stigma surrounding drug use and, for some, the intersection of other marginalized identities, such as being part of the LGBTQ+ community. In public spaces, the risk of being seen or judged made people reluctant to seek out testing services, even if they were available.
Another major factor complicating the picture was the nature of drug use itself. The study found that most participants used multiple substances at the same time, a practice known as polysubstance use. This was often an intentional strategy to manage the effects of different drugs, such as balancing a stimulant with a depressant. Current drug checking tools, like test strips, usually only detect one specific substance at a time, such as fentanyl. Participants felt frustrated by this limitation. They wanted to know the full composition of what they were taking, including the concentration of different drugs and the presence of other adulterants. A test strip that only says "fentanyl present" or "fentanyl absent" did not give them the complete picture they needed to make a safe decision. They expressed a desire for more advanced technology that could analyze the entire mixture, but such tools were not readily available to them.
The researchers also looked at the practical side of getting a test done. Many participants said that testing felt like too much work or an extra step that interrupted their routine. If they had to wait for a test result or travel to a specific location, they often chose not to do it, especially if they were experiencing withdrawal or a strong urge to use. The urgency of the moment often overrode the intention to be safe. Furthermore, many people did not know how to use the testing tools correctly or where to find them. Those who were already connected to harm reduction services were more likely to know how to test and to have access to the supplies, highlighting a gap in education and access for those on the margins.
The study concludes that the path forward for drug checking in the South requires more than just legal changes or the distribution of test strips. While the new law in Georgia is a positive step, it does not automatically solve the problem of trust and access. The researchers argue that successful implementation must happen within trusted community spaces, led by people who have lived experience with drug use. Services need to be designed to protect privacy and anonymity, addressing the very real fear of police involvement. Additionally, the tools themselves need to evolve to match the reality of polysubstance use, offering more comprehensive analysis rather than single-substance checks.
Ultimately, the study shows that saving lives through drug checking is not just a technical challenge but a social one. It requires building a system where people feel safe enough to engage, where the tools match their complex needs, and where the community leads the way. Without addressing the deep-seated issues of mistrust, stigma, and the practical realities of daily life, even the best-intentioned harm reduction strategies may fail to reach the people who need them most. The work done in Fulton County provides a clear roadmap: to make drug checking effective, it must be embedded in the trust and relationships that already exist within the community.
