Without a Trace

A note to readers: The need to write this essay came from conversations my friend and collaborator Denise Huskins and I had after curating What Were You Wearing? exhibits in Charleston and North Charleston, South Carolina, last month. Denise shared with me that she had heard stories about drink-spiking in local bars. Some of the stories were about cases where bartenders had facilitated spiking women’s drinks at the request of other patrons, resulting in drug-facilitated sexual assaults. We decided that we needed to look into this further. What follows is my initial research and analysis.

Evidence matters. We need evidence. We need to take it seriously. We need to collect it carefully, preserve it properly, and interpret it with scientific and moral clarity. Evidence is part of the record. Evidence can corroborate what happened. Evidence can interrupt denial. Evidence can expose patterns. Evidence can prevent institutions from treating a survivor’s word as if it exists alone, unsupported, and easy to dismiss.

But we also need to recognize that there is a class of cases—a class of assaults—in which the mechanism of harm is also a mechanism of disappearance.

Drug-facilitated sexual assault (DFSA) presents a particular challenge because the evidence may begin vanishing before the survivor understands what happened, before she can reach a hospital, before the right test is ordered, before law enforcement is called, before the incident is coded properly, before anyone in power agrees that what happened is worth documenting at all. That is the structural problem.

DFSA is not only an act of sexual violence. It is a form of violence that can erase or degrade the very record the survivor is later asked to produce.

DFSA is sexual violence accomplished or attempted through the administration of a substance that renders the victim unable to consent, resist, clearly perceive what is happening, or remember what occurred. It occurs in nightlife settings, dating and party contexts, marital and intimate-partner relationships, workplaces, residential settings, campus environments, rural communities, and tourist economies.

The public imagination often narrows this harm to the image of a stranger dropping something into a drink at a bar. That happens. But the harm is not confined to that story. Any substance capable of impairing consciousness, memory, judgment, coordination, perception, or physical resistance can be weaponized by a perpetrator.

And once it is weaponized, the survivor’s body becomes both the site of the harm and the site where the trace of that harm may begin to disappear.

Drug-facilitated sexual assault is not only an evidentiary problem. It is a biological and physiological one. The substances associated with DFSA can affect the central nervous system, memory, motor control, perception, consciousness, and the capacity to resist, seek help, or reconstruct what happened afterwards. Confusion, vomiting, loss of coordination, dissociation, blackout, delayed recognition, fragmented memory, and difficulty producing a linear account may all be consistent with the mechanism of harm. They should not be used to discredit the survivor. And yet, again and again, this is precisely what happens.

Survivors are asked to remember events that substances may have made impossible to remember. They are asked to report quickly after an assault they may not yet understand. They are asked to produce toxicology results after the detection window has closed. They are asked to provide chronological coherence when the substances involved may have disrupted memory and consciousness. This is not a survivor credibility problem. It is an institutional design problem. The system continues to demand evidence that the mechanism of harm may already have begun to erase.

Toxicology is often treated as the decisive evidentiary issue in suspected drink-spiking cases. That framing is misleading. Toxicology is important, but it cannot carry the entire evidentiary burden. The substances associated with drug-facilitated sexual assault vary widely in detectability. Some clear quickly. Some require specialized testing. Some are not included in routine emergency-department panels. Some may be detectable only if samples are collected within a narrow window. Some may be detectable in hair only later, and only through specialized testing that is not routinely available.

Alcohol may be present because it was voluntarily consumed, covertly administered, or both. The presence of a substance does not by itself establish consent. The absence of a substance does not establish that no drugging occurred.

This is the central toxicology problem: the system often waits for a kind of evidence that the mechanism of the assault is designed to erase.

Published forensic literature identifies GHB as especially difficult to document because it clears quickly. Blood and urine detection windows are measured in hours, not days. It is also a naturally occurring substance in the body, which adds another layer to the "toxicology trap"—making it even harder to prove "exogenous" (outside) administration. Most survivors of suspected drink spiking do not present to an emergency department within the GHB detection window, and many do not present within the window for other commonly associated substances either. So when institutions treat negative toxicology as if it settles the matter, they are not simply interpreting evidence. They are misreading the structure.

Negative toxicology does not prove spiking. But neither does it disprove spiking. The evidentiary limitations run in both directions. Any serious data system must be capable of recording suspected drug-facilitated sexual assault without requiring toxicology confirmation as the threshold for institutional recognition.

This distinction matters. The purpose is not to inflate prevalence claims beyond the evidence. The purpose is to show that the evidence infrastructure itself is too narrow to capture the phenomenon with accuracy.

This is not an argument against evidence. It is an argument for taking evidence seriously enough to understand its limits. What we know is that we need toxicology testing. We need forensic exams. We need hospital protocols. We need chain of custody. We need surveillance preservation. We need incident reports. We need trained responders. We need careful documentation. We need the record.

The Pelicot case makes this point unavoidable. Gisèle Pelicot was drugged and rendered unconscious while her then-husband Dominique Pelicot recruited men to rape her over a period of years. She did not know what had been done to her until police found images and videos of the assaults on Dominique Pelicot’s computer equipment. In that case, the record existed because the perpetrator had created it. That is what makes the case both horrifying and instructive: evidence matters, and when it exists, it can force a structure into view. But the Pelicot case should not comfort us. It should sharpen the question. What happens in the far more common cases where there is no perpetrator-created archive, no preserved video, no timely toxicology, and no institution willing to treat the survivor’s fragmented memory as part of the evidence rather than as a credibility defect?

Evidence does not collect itself. It requires systems willing and able to act within the window in which evidence can still be found. That is where DFSA exposes the failure.

If a survivor does not know what happened until the next day, the evidence may already be compromised. If the emergency department does not test, the evidence is not collected. If law enforcement treats the survivor’s uncertainty as unreliability, the evidence may never be pursued. If the venue fails to preserve video, the record narrows. If the incident is coded as intoxication, suspicious circumstances, or an alcohol-related event rather than suspected drug-facilitated assault, the case disappears into the wrong category.

At every stage, evidence can be lost. Not because the harm did not occur. Because the structure did not or could not preserve the record.

This is the particular challenge DFSA presents: it requires institutions to move with urgency while also understanding uncertainty. It requires them to collect evidence without demanding that the survivor already have a complete narrative. It requires them to recognize that memory gaps, confusion, delayed recognition, and negative toxicology may be features of the assault rather than evidence against the survivor. That requires a different epistemology. It requires institutions to stop treating the survivor as the weak link in the record, when the weak link is often the system itself.

The United States does not currently have a coherent data infrastructure capable of measuring drink spiking or drug-facilitated sexual assault with accuracy. Existing federal datasets capture sexual assault, victimization, law-enforcement reporting, and some drug-related offenses, but they do not distinguish drink spiking as a specific pathway into sexual violence. That absence is not merely a research gap. It is part of the problem under analysis.

No federal-level dataset distinguishes drink-spiking incidents from other sexual-assault statistics. State-level criminal codes vary significantly in how they categorize spiking, producing local data that cannot be aggregated even where local agencies record specific incident types. Hospital-level data is collected under HIPAA-governed frameworks that limit aggregation across institutions and jurisdictions. Toxicology-positive cases are a small and structurally non-representative subset because many suspected cases are never tested, are tested too late, or require specialized testing that is not ordered.

Survivor-built reporting infrastructure has begun to emerge in response to this gap. These platforms are methodologically limited, but they capture cases that the institutional record loses. That should tell us something.

We can already see this happening. In Nashville, Erika Gorman created SpikedInNash.com after a family member was drugged during a work event on Broadway, later waking disoriented and discovering that money had been taken from his accounts. The site allows people to anonymously submit details about suspected drink-spiking incidents, including where the incident occurred, whether they attempted to get a drug test, and what happened afterwards. More than two dozen incidents had already been submitted by the time local reporting covered the site. This is exactly the kind of survivor- and community-built infrastructure that emerges when official systems fail to capture the record. It is not a substitute for a coherent public data system. It is evidence that such a system is missing.

The absence of comprehensive data on drink spiking is not a neutral measurement problem awaiting a better survey instrument. It is a structural feature of the institutional response. The toxicology window prevents many cases from generating confirmatory evidence. Statutory frameworks prevent some cases from being charged unless additional harm occurs. Hospitals vary in whether testing is offered or performed. Law-enforcement agencies vary in how incidents are coded. Venues may have reputational and licensing incentives not to document incidents. Campuses may treat cases as alcohol-policy violations rather than evidence of predatory conduct. Tourist economies may have financial incentives to suppress the appearance of risk. Rural communities may lack anonymity, transportation, and forensic medical access.

In other words, the data gap is not accidental. It is produced. The architecture does not merely fail to count the harm. It helps make the harm disappear.

This is where the biological record becomes a credibility question.

If a survivor cannot remember, she may be treated as unreliable. If a survivor delays reporting, she may be treated as someone who just has “remorse.” If a survivor was drinking, the inquiry may be turned back onto her. If a survivor has a negative toxicology screen, the case may be treated as if it has already collapsed. If a survivor cannot provide a coherent linear account, the institutional response may turn into doubt rather than into an investigation.

This is the lexicon of the perpetrator functioning as public inquiry: What were you drinking? Why were you there? Were you alone? Weren’t you watching your drink? Why can’t you remember?

These questions are not random. They are the structural form of cultural disbelief. They move agency and accountability away from the perpetrator and back onto the victim.

In a culture where violence against women is normalized, women’s risk assessment is treated as distortion while men’s habits are treated as background. Survivors are trained to distrust our own perception. Pattern recognition becomes hysteria. Fear is pathologized. Fragmented memory becomes a credibility problem rather than a possible consequence of the mechanism itself. This is why survivor epistemology matters.

Survivors are not unreliable narrators by default. Embodied knowledge is knowledge. Fragmented memory is not proof of fabrication. Delayed recognition is not proof that nothing happened. And the absence of a chemical trace is not proof that violence did not occur.

Without an explicit framework in place to address and adequately and appropriately respond to these issues, survivors are asked to accept the terms of our own discrediting. That is what we are refusing.

Drug-facilitated sexual assault exposes a central problem in the institutional response to sexual violence: the system continues to demand perfect evidence from people harmed by a mechanism that often makes providing perfect evidence impossible.

The response cannot be limited to better testing, although better testing is needed. It cannot be limited to better police training, although better police training is needed. It also cannot be limited to better survivor education, because survivors are not the cause of the harm. The response must be structural.

That means recognizing drink spiking as a distinct form of violence and coercion. It means creating federal and state data systems capable of counting it. It means treating nonconsensual administration of a substance as a serious offense whether or not a sexual assault follows. It means building medical protocols that understand toxicology limits. It means funding SANE access where it does not exist. It means requiring venues, campuses, hospitals, law enforcement, prosecutors, and policymakers to act before harm disappears into institutional gaps.

It also means confronting the asymmetry in how we hold bars, restaurants, clubs, and other licensed venues accountable. We already understand, through dram shop laws, that licensed establishments can be held responsible when their practices contribute to foreseeable harm. In many jurisdictions, the law recognizes that over-serving an intoxicated patron is not simply a private matter between the patron and the bar. If that patron later harms someone, the venue’s conduct can become part of the legal and moral record. The law already knows how to ask whether a licensed establishment contributed to risk.

Tennessee lawmakers are now considering one version of that shift. As Madeleine Nolan recently reported for local Nashville media, House Bill 2301 would make intentional drink spiking a felony offense and require bars and restaurants licensed to sell alcohol to keep drink-testing devices available for customers who suspect their drinks have been tampered with. The bill would also require notices informing customers that testing devices are available. This matters because it begins to move the burden where it belongs: onto the systems and venues that profit from these environments and control access to the record.

But when the harm is covert drugging on the premises, the architecture changes. The venue may have every incentive to minimize, delay, miscode, or avoid documentation. The survivor may be treated as merely intoxicated. Staff may fail to preserve surveillance footage. Security may remove the victim rather than protect them. A report may never be made. A record may never form. That is the dram shop asymmetry.

The law has built pathways for holding venues accountable when over-service leads to harm by an intoxicated patron. But it has not, in the same systematic way, built comparable pathways for holding venues accountable when harm occurs to a patron through covert drugging on the premises.

That asymmetry matters. It reflects a deeper problem in how the law understands risk: harm caused by intoxicated patrons is legible; harm done to intoxicated or drugged women is too often treated as confusion, excess, or personal responsibility. That has to change.

This is especially important in cases where the venue is not a passive site of harm. If the harm runs through staff, then the question of venue accountability is not theoretical but concrete and urgent.

Testing strips may be one part of that response, but they are not enough. They do not preserve surveillance footage. They do not create an incident report. They do not train staff. They do not identify patterns. They do not answer the question of what happens when staff themselves are implicated in the harm.

Bars, clubs, restaurants, event spaces, hotels, and tourist venues should not be allowed to treat drink spiking as a reputational inconvenience. If venues profit from environments where intoxication is expected, where alcohol is sold, where surveillance exists, where staff control access, exits, security, and reporting pathways, then they must also carry affirmative duties to prevent, recognize, document, and respond to suspected drink spiking.

Most of all, it means refusing to treat the absence of evidence as the absence of violence when the absence itself has been produced by the structure. The task now is to build a structure that does not require survivors to become perfect evidence before institutions are willing to act.

Without a trace does not mean without harm. Without a trace may mean the evidence window closed before the survivor understood what happened. It may mean no one ordered the right test. It may mean the hospital did not have the protocol. It may mean the police misread the science. It may mean the case was coded into the wrong category. It may mean the venue had an incentive not to document the incident. It may mean the survivor anticipated disbelief and did not report. It may mean the institution refused to know.

This is not merely a problem of missing information. It is a problem of how systems decide what information matters, whose knowledge counts, and when the absence of a record is allowed to stand in for the absence of harm.

That is what forensic moral philosophy asks us to examine: not only what happened, but how the record was produced; how the record was narrowed; how credibility was granted, denied, or strategically dismantled; and how violence was made administratively survivable for the institutions that failed to see it.

We already hold bars and servers accountable in many states when over-service foreseeably contributes to harm. We need a comparable accountability framework for venues where drink spiking is reported, suspected, ignored, mishandled, or allowed to vanish without documentation.

The same legal infrastructure that recognizes venue responsibility in dram shop cases must be brought to bear here. Not because evidence does not matter, but because evidence matters so much that venues should not be allowed to let it disappear.

If you or someone you know has been affected by sexual violence, you are not alone.
