"You Have to Be a Doctor First": Trauma Surgeons' Perspectives on Police Interactions in the Hospital

BACKGROUND

Police activity in emergency medical settings has been shown to complicate the care of patients and impact patient-provider relationships. Recent scholarship has called for clear hospital policy outlining the terms of police access to patients and the role of clinicians. Despite regular contact between trauma surgeons and police, research on the impact of police activity on trauma care has been limited.

METHODS

Semi-structured interviews were conducted with attending trauma surgeons and general surgery residents (N = 13) at 3 urban hospitals about their interactions with police in clinical settings. Participants were recruited using snowball sampling. Interviews were audio-recorded, transcribed, and analyzed for recurrent themes using an iterative grounded theory process.

RESULTS

Participants reported routine contact with police that required active negotiation of the scope of clinical and police authority in the hospital. These negotiations were shaped by prior experiences, perceptions of police, officer behavior, and institutional culture. Surgeons felt compelled to advocate for patients, but reported intimidation in moments of conflict. Participants noted uncertainty around the legal dimensions of their relationship to police and a lack of universal guidance on appropriate responses.

DISCUSSION

This data points to the need for improvements in both policy and workflow to regulate and reduce the burden of these interactions and protect clinicians' priorities from being subordinated to those of police. Further research is needed to understand how police presence impacts patient outcomes, and to guide best practices for regulating and mitigating potential negative impact.

Decreasing Stigma Toward People Who Inject Drugs: Harm Reduction Training for First-Year Medical Students

PROBLEM

Stigma in health care toward people who inject drugs (PWID) is a well described, significant barrier to quality care, resulting in poor health outcomes. Harm reduction offers a person-centered counter-framework for minimizing harm for people who use drugs. Despite the evidence in support of harm reduction, medical students typically receive minimal training on harm reduction and the care of PWID.

APPROACH

To fill this gap, medical students at University of California, Los Angeles organized around the principles of harm reduction to improve the medical school curriculum related to PWID. Students screened lectures for stigmatizing language and collaborated with faculty to improve lecture materials. They partnered with a community organizer and hosted a mandatory 1-hour lecture and 30-minute discussion introducing the principles of harm reduction within an overdose prevention, recognition, and response training for first-year medical students during medical school orientation in August 2022. An anonymous online pre- and posttest survey, assessing student attitudes toward PWID, was used to evaluate the effects of the training.

OUTCOMES

A total of 156 students completed the pretest survey, and 107 students completed the pre- and posttest survey (68.5% response rate). The overall posttest mean stigma score was 1.8 (standard deviation [SD] = 0.5) and was significantly lower than the pretest mean of 2.1 (SD = 0.7; P < .0001), indicating a reduction in stigma among medical student attitudes after the course. There was statistically significant improvement in attitudes for 7 of 13 component measures.

NEXT STEPS

This analysis demonstrated that the mandatory class has the capacity to improve medical student attitudes toward PWID. The authors plan to further evaluate the program's effectiveness through measuring and reporting outcomes for future student cohorts. The authors are working with curriculum directors to further incorporate harm reduction principles into other lectures and problem-based learning exercises.

A Qualitative Study of Perceptions and Preferences Regarding Social and Behavioral Risk Screening Among Primary Care Patients

BACKGROUND

Despite its relevance for healthcare settings, social and behavioral risk screening is not systematically performed by clinicians or healthcare systems.

OBJECTIVE

To address clinician concerns, such as social and behavioral risk screening disrupting the clinician-patient relationship and lack of resources to respond, we interviewed primary care patients at an academic medical center regarding their perceptions and preferences on social and behavioral risk screening.

PARTICIPANTS

Between September and December 2020, we recruited a convenience sample of 14 English-speaking primary care patients 18 years + from three clinics affiliated with an academic medical center.

APPROACH

Using a semi-structured interview guide, we asked about the importance of social and behavioral risk screening, whether or not and how to share social and behavioral risk factors, and how social and behavioral risk factors are addressed. We used a multi-step analytic process to identify the range and commonality of participants' responses thematically.

KEY RESULTS

Participants recognized that social and behavioral risk factor domains were relevant to primary care and important for treating the patient as a whole person. Participants preferred a conversation regarding social and behavioral risk factor with their primary care providers (PCPs), and suggested that, if surveys are used, they be followed with an open-ended, in-person discussion. Participants also suggested framing the discussion as something that is done routinely with all patients so that patients do not feel judged. Participants felt comfortable sharing social and behavioral risk factors when they trusted their PCPs, and felt that discussing social and behavioral risk factors with their PCPs built trust. Participants recognized that resources exist outside of the clinic, and suggested that PCPs distribute lists of relevant community resources to patients.

CONCLUSION

In our study of primary care patients on perceptions and preferences about screening and addressing social and behavioral risk factors, we found that patients were willing to share social and behavioral risk factors with their PCP, preferred an in-person discussions with or without a survey, and wanted a list of community resources to address their needs.

Rethinking urban-rural designations in public health surveillance of the overdose crisis and crafting an agenda for future monitoring

Rurality has served as a key concept in popular and scientific understandings of the US overdose crisis, with White, rural, and low-income areas thought to be most heavily affected. However, we observe that overdose trends have risen nearly uniformly across the urban-rural designations employed in most research, implying that their importance has likely been overstated or incorrectly conceptualized. Nevertheless, urbanicity/rurality does serve as a key axis to understand inequalities in overdose mortality when assessed with more nuanced modalities-employing a more granular analysis of geography at the sub-county level, and intersecting rurality sociodemographic indices such as race/ethnicity. Using national overdose data from 1999-2021, we illustrate the intersectional importance of rurality for overdose surveillance. Finally, we offer recommendations for integrating these insights into drug overdose surveillance moving forward.

Fentanyl, heroin, and methamphetamine-based counterfeit pills sold at tourist-oriented pharmacies in Mexico: An ethnographic and drug checking study

BACKGROUND

Fentanyl- and methamphetamine-based counterfeit prescription drugs have driven escalating overdose death rates in the US, however their presence in Mexico has not been assessed. Our ethnographic team has conducted longitudinal research focused on illicit drug markets in Northern Mexico since 2018. In 2021-2022, study participants described the arrival of new, unusually potent tablets sold as ostensibly controlled substances, without a prescription, directly from pharmacies that cater to US tourists.

AIMS

To characterize the availability of counterfeit and authentic controlled substances at pharmacies in Northern Mexico available to English-speaking tourists without a prescription.

METHODS

We employed an iterative, exploratory, mixed methods design. Longitudinal ethnographic data was used to characterize tourist-oriented micro-neighborhoods and guide the selection of n=40 pharmacies in n=4 cities in Northern Mexico. In each pharmacy, samples of "oxycodone", "Xanax", and "Adderall" were sought as single pills, during English-language encounters, after which detailed ethnographic accounts were recorded. We employed immunoassay-based testing strips to check each pill for the presence of fentanyls, benzodiazepines, amphetamines, and methamphetamines. We used Fourier-Transform Infrared Spectroscopy to further characterize drug contents.

RESULTS

Of n=40 pharmacies, one or more of the requested controlled substances could be obtained with no prescription (as single pills or in bottles) at 28 (70.0%) and as single pills at 19 (47.5%). Counterfeit pills were obtained at 11 pharmacies (27.5%). Of n=45 samples sold as one-off controlled substances, 18 were counterfeit. 7 of 11 (63.6%) samples sold as "Adderall" contained methamphetamine, 8 of 27 (29.6%) samples sold as "Oxycodone" contained fentanyl, and 3 "Oxycodone" samples contained heroin. Pharmacies providing counterfeit drugs were uniformly located in tourist-serving micro-neighborhoods, and generally featured English-language advertisements for erectile dysfunction medications and "painkillers". Pharmacy employees occasionally expressed concern about overdose risk and provided harm reduction guidance.

DISCUSSION

The availability of fentanyl-, heroin-, and methamphetamine-based counterfeit medications in tourist-oriented independent pharmacies in Northern Mexico represents a public health risk, and occurs in the context of 1) the normalization of medical tourism as a response to rising unaffordability of healthcare in the US, 2) plummeting rates of opioid prescription in the US, affecting both chronic pain patients and the availability of legitimate pharmaceuticals on the unregulated market, 3) the rise of fentanyl-based counterfeit opioids as a key driver of the fourth, and deadliest-to-date, wave of the opioid crisis. It was not possible to distinguish counterfeit medications based on appearance of pills or geography of pharmacies, because identically-appearing authentic and counterfeit versions were often sold in close geographic proximity. Nevertheless, people who consume drugs may be more trusting of controlled substances purchased directly from pharmacies. Due to Mexico's limited opioid overdose surveillance infrastructure, the current death rate from these substances remains unknown.

"A lotta people switched playing hard ball to playing Russian roulette": Experiences with rising overdose incidence caused by drug supply changes during the COVID-19 pandemic in the San Diego-Tijuana border metroplex

Background

People who use drugs (PWUD) in the San Diego, USA and Tijuana, Mexico metroplex face high overdose risk related to historic methamphetamine use and relatively recent fentanyl introduction into local drug supplies. The personal overdose experiences of PWUD in this region are understudied, however, and may have been influenced by the COVID pandemic.

Methods

From September-November 2021, we conducted 28 qualitative interviews among PWUD ≥18 years old sampled from an ongoing cohort study in the San Diego-Tijuana metroplex. Interviews explored overdose experiences and changes in the drug supply. Thematic analysis of coded interview transcripts explored overdose experiences, perspectives on drug supply changes, interactions with harm reduction services, and naloxone access.

Results

Among 28 participants, 13 had experienced an overdose. Participants discussed rising levels of fentanyl in local drug supplies and increasing overdose incidents in their social networks. Participants discussed a general shift from injecting heroin to smoking fentanyl in their networks. Participants' most common concerns included having consistent access to a safe and potent drug supply and naloxone.

Conclusion

Participants prioritized adapting to drug supply changes and preventing overdose compared to other health concerns, such as HIV and COVID-19. Efforts to address overdose in this region could benefit from drug checking services and expanded, equitable delivery of naloxone.

Fentanyl, Heroin, and Methamphetamine-Based Counterfeit Pills Sold at Tourist-Oriented Pharmacies in Mexico: An Ethnographic and Drug Checking Study

Background

Our ethnographic team has conducted longitudinal research focused on illicit drug markets in Northern Mexico since 2018. In 2021-2022, study participants described the arrival of new, unusually potent tablets sold as ostensibly controlled substances, without a prescription, directly from pharmacies that cater to US tourists. Concurrently, fentanyl- and methamphetamine-based counterfeit prescription drugs have driven escalating overdose death rates in the US, however their presence in Mexico has not been assessed.

Aims

To characterize the availability of counterfeit and authentic controlled substances at pharmacies in Northern Mexico available to English-speaking tourists without a prescription.

We employed immunoassay-based testing strips to check each pill for the presence of fentanyls, benzodiazepines, amphetamines, and methamphetamines. We used Fourier-Transform Infrared Spectroscopy to further characterize drug contents.

Results

Of 40 pharmacies, these controlled substances could be obtained in any form with no prescription at 68.3% and as single pills at 46.3%. Counterfeit pills were obtained at n=11 (26.8%) of pharmacies. Of n=45 samples sold as one-off controlled substances, n=20 were counterfeit including 9 of 11 (81.8%) of samples sold as "Adderall" that contained methamphetamine, and 8 of 27 (29.6%) of samples sold as "Oxycodone" that contained fentanyl, and n=3 'Oxycodone' samples containing heroin. Pharmacies providing counterfeit drugs were uniformly located in tourist-serving micro-neighborhoods, and generally featured English-language advertisements for erectile dysfunction medications and 'painkillers'. Pharmacy employees occasionally expressed concern about overdose risk and provided harm reduction guidance.

Discussion

The availability of fentanyl-, heroin-, and methamphetamine-based counterfeit medications in Northern Mexico represents a public health risk, and occurs in the context of 1) the normalization of medical tourism as a response to rising unaffordability of healthcare in the US, 2) plummeting rates of opioid prescription in the US, affecting both chronic pain patients and the availability of legitimate pharmaceuticals on the unregulated market, 3) the rise of fentanyl-based counterfeit opioids as a key driver of the fourth, and deadliest-to-date, wave of the opioid crisis. It is not possible to distinguish counterfeit medications based on appearance, because identically-appearing authentic and counterfeit versions are often sold in close geographic proximity. Nevertheless, US tourist drug consumers may be more trusting of controlled substances purchased directly from pharmacies. Due to Mexico's limited opioid overdose surveillance infrastructure, the current death rate from these substances remains unknown.

Potency-Enhancing Synthetics in the Drug Overdose Epidemic: Xylazine ("Tranq"), Fentanyl, Methamphetamine, and the Displacement of Heroin in Philadelphia and Tijuana

Multiple transformations-referred to as "waves" in a panoply of recent public health and law enforcement publications-have rendered North American drug markets increasingly toxic since the early 2010s. The introduction of exceptionally potent synthetic sedatives and stimulants is initiating a new generation of drug injectors into co-use of opioids and methamphetamine, catapulting rates of deadly overdoses and infectious diseases. Drawing on extensive participant-observation research in Philadelphia (2007-present) and Tijuana (2018-present), we document the experience of street-based drug users across these two North American cities to focus on regional shifts in narcotics supplies and endpoint user preferences. We link the dramatic proliferation of fentanyl, methamphetamine, xylazine, and Mexican white powder heroin to: 1) pre-existing drug supply networks on the western and eastern coasts of the North American subcontinent; 2) material characteristics of local heroin supplies in pre-fentanyl opiate markets (Mexican black tar vs. Colombian off-white powder heroin); and 3) racialized repression/incarceration of drug sellers and users on both sides of the Mexico-US border. The article combines economic and medical anthropology to develop an ethnographically-informed political economy approach to an urgent public health challenge among street-based drug users with the highest overdose mortality rates in the US Northeastern Rust Belt and the Northwestern Mexican borderland metroplex anchored by Tijuana. It foregrounds street users' experiences in real time amidst rapidly shifting narcotics supply chains, linking market-driven logics of profit-seeking to the war on drugs' prohibitionist policy context, highlighting increasing toxic impacts on vulnerable sectors across regions.

Substance use policy and practice in the COVID-19 pandemic: Learning from early pandemic responses through internationally comparative field data

The COVID-19 pandemic has created an unprecedented natural experiment in drug policy, treatment delivery, and harm reduction strategies by exposing wide variation in public health infrastructures and social safety nets around the world. Using qualitative data including ethnographic methods, questionnaires, and semi-structured interviews with people who use drugs (PWUD) and Delphi-method with experts from field sites spanning 13 different countries, this paper compares national responses to substance use during the first wave of the COVID-19 pandemic. Field data was collected by the Substance Use x COVID-19 (SU x COVID) Data Collaborative, an international network of social scientists, public health scientists, and community health practitioners convened to identify and contextualise health service delivery models and social protections that influence the health and wellbeing of PWUD during COVID-19. Findings suggest that countries with stronger social welfare systems pre-COVID introduced durable interventions targeting structural drivers of health. Countries with fragmented social service infrastructures implemented temporary initiatives for PWUD led by non-governmental organisations. The paper summarises the most successful early pandemic responses seen across countries and ends by calling for greater systemic investments in social protections for PWUD, diversion away from criminal-legal systems toward health interventions, and integrated harm reduction, treatment and recovery supports for PWUD.

Correlates of recent overdose among people who inject drugs in the San Diego/Tijuana border region

BACKGROUND

Along the Mexico-US border, illicitly manufactured fentanyls (fentanyl) have been detected in other illicit drugs, including street opioid formulations known as 'china white.' We studied correlates of recent overdose among people who inject drugs (PWID), focusing on the risk of knowlingly or unknowingly using fentanyl in china white.

METHODS

From October 2020 - September, 2021 we surveyed participants in San Diego, California and Tijuana, Mexico and employed Poisson regression to identify correlates of recent overdose.

RESULTS

Of 612 PWID, most were male (74.0 %), Latinx (71.9 %), US residents (67.0 %). Mean age was 43 years. In the last six months, 15.8 % experienced overdose, 31.0 % knowingly used fentanyl and 11.1 % used china white, of whom 77.9 % did not think it contained fentanyl. After controlling for sex and race, factors independently associated with risk of overdose included knowingly using fentanyl, using china white and not believing it contained fentanyl, recent drug rehabilitation, being stopped/arrested by police, and homelessness. Further, PWID who believed china white contained fentanyl were less likely to use it.

CONCLUSIONS

Both intentional fentanyl use and unintentional exposure to fentanyl via china white were associated with overdose risk; however, PWID who believed china white contained fentanyl were less likely to use it. These data suggest that advanced drug checking systems should be implemented to empower PWID to avoid dangerous street formulations or to plan their drug use knowing its contents. Other overdose risk factors such as decreased tolerance following drug treatment, police interactions, and homelessness also require urgent intervention.

Client Outreach in Los Angeles County's Assisted Outpatient Treatment Program: Strategies and Barriers to Engagement

Purpose

Assisted Outpatient Treatment (AOT) programs can compel treatment-refusing individuals to participate in mental health treatment via civil court order. In California's AOT programs, individuals first must be offered 30 days of outreach services and can accept services voluntarily. This study examines the use of outreach strategies in an AOT program with the potential for voluntary or involuntary enrollment.

Methods

Outreach staff completed a survey in which they reported and rated outreach strategies and barriers to treatment for 487 AOT-referred individuals.

Results

Outreach staff reported using a broad array of strategies to persuade and engage clients. Supportive and persuasive strategies were most common. More coercive strategies, including court order, were used when needed. More clients enrolled voluntarily (39.4%) than involuntarily (7.2%).

Conclusions

Outreach, coupled with the strategic used of potential court involvement, can lead to voluntary enrollment of treatment-refusing individuals with many, often severe, barriers to engaging in outpatient treatment.

Deported, homeless, and into the canal: Environmental structural violence in the binational Tijuana River

Introduction:

The US deports more Mexicans to Tijuana than any other borderland city. Returning involuntarily as members of a stigmatized underclass, many find themselves homeless and de-facto stateless. Subject to routinized police victimization, many take refuge in the Tijuana River Canal (El Bordo). Previous reports suggest Tijuana River water may be contaminated but prior studies have not accessed the health effects or contamination of the water closest to the river residents.

Methods:

A binational, transdisciplinary team undertook a socio-environmental, mixed methods assessment to simultaneously characterize Tijuana River water quality with chemical testing, assess the frequency of El Bordo residents’ water-related diseases, and trace water contacts with epidemiological survey methods (n = 85 adults, 18+) in 2019, and ethnographic methods in 2019–2021. Our analysis brings the structural violence framework into conversation with an environmental injustice perspective to documented how social forces drive poor health outcomes enacted through the environment.

Results:

The Tijuana River water most proximate to its human inhabitants fails numerous water-quality standards, posing acute health risks. Escherichia coli values were ∼40,000 times the Mexican regulatory standard for directly contacted water. Skin infections (47%), dehydration (40%) and diarrhea (28%) were commonly reported among El Bordo residents. Residents are aware the water is contaminated and strive to minimize harm to their health by differentially using local water sources. Their numerous survival constraints, however, are exacerbated by routine police violence which propels residents and other people who inject drugs into involuntary contact with contaminated water.

Discussion:

Human rights to drinking water, sanitation and hygiene are routinely violated among El Bordo in-habitants. This is exacerbated by violent policing practices that force unhoused deportees to seek refuge in waterways, and drive water contacts. Furthermore, US-Mexico ‘free-trade’ agreements drive rapid growth in Tijuana, restrict Mexican environmental regulation enforcement, and drive underinvestment in sewage systems and infrastructure.

The introduction of fentanyl on the US-Mexico border: An ethnographic account triangulated with drug checking data from Tijuana

BACKGROUND

Illicitly-manufactured fentanyls (fentanyl) have changed the risk environment of people who use drugs (PWUD). In California and many western US states, the opioid overdose rate spiked from 2016 to 2021, driven largely by fentanyl. Mexican border cities act as transit through-points for the illicit drug supply and similar evolving health risks are likely to be present. Nevertheless, due to data gaps in surveillance infrastructure, little is known about fentanyl prevalence in Mexico.

METHODS

We employ intensive ethnographic participant-observation among PWUD, as well as key informants including harm reduction professionals, EMTs, and physicians on the front lines in Tijuana, Mexico. We triangulate interview data and direct observations of consumption practices with n=652 immunoassay-based fentanyl tests of drug paraphernalia from mobile harm reduction clinics in various points throughout the city.

RESULTS

PWUD informants described a sharp increase in the psychoactive potency and availability of powder heroin-referred to as "china white"-and concomitant increases in frequency of overdose, soft tissue infection, and polysubstance methamphetamine use. Fentanyl positivity was found among 52.8% (95%CI: 48.9-56.6%) of syringes collected at harm reduction spaces, and varied strongly across sites, from 2.7% (0.0-5.7%) to 76.5% (68.2-84.7%), implying strong market heterogeneity. Controlling for location of collection, syringe-based fentanyl positivity increased by 21.7% (10.1-42.3%) during eight months of testing. Key informants confirm numerous increased public health risks from fentanyl and describe the absence of a systematic or evidence-based governmental response; naloxone remains difficult to access and recent austerity measures have cut funding for harm reduction in Mexico.

CONCLUSIONS

Fentanyl, linked to powder heroin, is changing the risk environment of PWUD on the US-Mexico border. Improved surveillance is needed to track the evolving street drug supply in Mexico and related health impacts for vulnerable populations. Structural factors limiting access to naloxone, harm reduction, substance use treatment, and healthcare, and minimal overdose surveillance, must be improved to provide an effective systemic response.

An Ethnographic Assessment of COVID-19‒Related Changes to the Risk Environment for People Who Use Drugs in Tijuana, Mexico

Objectives. To characterize the effects of the onset of the COVID-19 pandemic on the risk environment of people who use drugs (PWUD) in Tijuana, Mexico. Methods. We used intensive participant-observation ethnography among street-based PWUD and key informants, such as frontline physicians and harm reductionists. Results. PWUD described an unprecedented cessation of police violence and extortion during the initial pandemic-related lockdown, though this quickly reversed and police violence worsened. Government-provided housing and medical treatment with methadone were temporarily provided to PWUD in a dedicated clinic, yet only for PWUD with COVID-19 symptoms. Concurrently, non‒COVID-19‒related hospital care became virtually inaccessible, and many PWUD died of untreated, chronic illnesses, such as hepatitis C, and soft-tissue infections. Border closures, decreases in social interaction, and reduced drug and sex tourism resulted in worsening food, income, and housing insecurity for many PWUD. By contrast, potent illicit drugs remained easily accessible in open-air drug markets. Conclusions. The pandemic exacerbated health risks for PWUD but also offered profound glimpses of beneficial structural changes. Efforts are needed in Tijuana and elsewhere to institutionalize positive pandemic-related shifts and ameliorate novel harms for PWUD.

Prevalence and predictors of recent temporary psychiatric hold among a cohort of people who inject drugs in Los Angeles and San Francisco, California

California's Welfare and Institutions code 5150 allows for a temporary psychiatric hold (TPH) of individuals who present a danger to themselves or others and/or may be gravely disabled due to mental illness. Little is known about the frequency and predictors of involuntary holds among people who inject drugs (PWID).

METHODS

We sought to identify the prevalence and predictors of recent TPHs (within the past 12 months) among a community-recruited sample of PWID in Los Angeles and San Francisco, California during 2017-2018 (N = 531). Multivariable logistic regression modeling was used to evaluate demographic (e.g., age), economic (e.g., homelessness), drug use (e.g., types of drugs used), incarceration (e.g., recent arrest history) and mental health (e.g., lifetime mental health diagnosis) variables associated with recent TPH.

RESULTS

Age (40-49 years old vs age 50 or older: AOR = 5.85; 95 % CI = 2.18, 15.67), current homelessness (AOR = 3.75; 95 % CI = 1.28, 11.0), lifetime mental health history (AOR = 6.23; 95 % CI = 2.08, 18.66), and frequency of methamphetamine use (AOR = 1.01; 95 % CI = 1.00, 1.01) were statistically associated with increased odds of having experienced a TPH, while frequency of past month heroin/opioid use was associated with decreased odds of reporting a TPH (AOR = 0.99; 95 % CI = 0.99, 1.00) in multivariable analysis.

CONCLUSIONS

Diverse factors were associated with TPH among PWID. Our analysis underscores the need for research on PWID with co-occurring substance-use and mental illness disorders and homelessness. There is urgent need for expanding access to lower barrier publicly funded mental health treatment from a harm-reduction approach.

Racial/Ethnic, Social, and Geographic Trends in Overdose-Associated Cardiac Arrests Observed by US Emergency Medical Services During the COVID-19 Pandemic

IMPORTANCE

Provisional records from the US Centers for Disease Control and Prevention (CDC) through July 2020 indicate that overdose deaths spiked during the early months of the COVID-19 pandemic, yet more recent trends are not available, and the data are not disaggregated by month of occurrence, race/ethnicity, or other social categories. In contrast, data from emergency medical services (EMS) provide a source of information nearly in real time that may be useful for rapid and more granular surveillance of overdose mortality.

OBJECTIVE

To describe racial/ethnic, social, and geographic trends in EMS-observed overdose-associated cardiac arrests during the COVID-19 pandemic through December 2020 and assess the concordance with CDC-reported provisional total overdose mortality through May 2020.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study included more than 11 000 EMS agencies in 49 US states that participate in the National EMS Information System and 83.7 million EMS activations in which patient contact was made.

EXPOSURES

Year and month of occurrence of overdose-associated cardiac arrest; patient race/ethnicity; census region and division; county-level urbanicity; and zip code-level racial/ethnic composition, poverty, and educational attainment.

MAIN OUTCOMES AND MEASURES

Overdose-associated cardiac arrests per 100 000 EMS activations with patient contact in 2020 were compared with a baseline of values from 2018 and 2019. Aggregate numbers of overdose-associated cardiac arrests and percentage increases were compared with provisional total mortality in CDC records from rolling 12-month windows with end months spanning January 2018 through July 2020.

RESULTS

Among 33.4 million EMS activations in 2020, 16.8 million (50.2%) involved female patients and 16.3 million (48.8%) involved non-Hispanic White individuals. Overdose-associated cardiac arrests were elevated by 42.1% nationally in 2020 (42.3 per 100 000 EMS activations at baseline vs 60.1 per 100 000 EMS activations in 2020). The highest percentage increases were seen among Latinx individuals (49.7%; 38.8 per 100 000 activations at baseline vs 58.1 per 100 000 activations in 2020) and Black or African American individuals (50.3%; 21.5 per 100 000 activations at baseline vs 32.3 per 100 000 activations in 2020), people living in more impoverished neighborhoods (46.4%; 42.0 per 100 000 activations at baseline vs 61.5 per 100 000 activations in 2020), and the Pacific states (63.8%; 33.1 per 100 000 activations at baseline vs 54.2 per 100 000 activations in 2020), despite lower rates at baseline for these groups. The EMS records were available 6 to 12 months ahead of CDC mortality figures and showed a high concordance (r = 0.98) for months in which both data sets were available. If the historical association between EMS-observed and total overdose mortality holds true, an expected total of approximately 90 632 (95% CI, 85 737-95 525) overdose deaths may eventually be reported by the CDC for 2020.

CONCLUSIONS AND RELEVANCE

In this cohort study, records from EMS agencies provided an effective manner to rapidly surveil shifts in US overdose mortality. Unprecedented overdose deaths during the pandemic necessitate investments in overdose prevention as an essential aspect of the COVID-19 response and postpandemic recovery. This is particularly urgent for more socioeconomically disadvantaged and racial/ethnic minority communities subjected to the compounded burden of disproportionate COVID-19 mortality and rising overdose deaths.

Structural vulnerability to narcotics-driven firearm violence: An ethnographic and epidemiological study of Philadelphia's Puerto Rican inner-city

BACKGROUND

The United States is experiencing a continuing crisis of gun violence, and economically marginalized and racially segregated inner-city areas are among the most affected. To decrease this violence, public health interventions must engage with the complex social factors and structural drivers-especially with regard to the clandestine sale of narcotics-that have turned the neighborhood streets of specific vulnerable subgroups into concrete killing fields. Here we present a mixed-methods ethnographic and epidemiological assessment of narcotics-driven firearm violence in Philadelphia's impoverished, majority Puerto Rican neighborhoods.

METHODS

Using an exploratory sequential study design, we formulated hypotheses about ethnic/racial vulnerability to violence, based on half a dozen years of intensive participant-observation ethnographic fieldwork. We subsequently tested them statistically, by combining geo-referenced incidents of narcotics- and firearm-related crime from the Philadelphia police department with census information representing race and poverty levels. We explored the racialized relationships between poverty, narcotics, and violence, melding ethnography, graphing, and Poisson regression.

FINDINGS

Even controlling for poverty levels, impoverished majority-Puerto Rican areas in Philadelphia are exposed to significantly higher levels of gun violence than majority-white or black neighborhoods. Our mixed methods data suggest that this reflects the unique social position of these neighborhoods as a racial meeting ground in deeply segregated Philadelphia, which has converted them into a retail endpoint for the sale of astronomical levels of narcotics.

IMPLICATIONS

We document racial/ethnic and economic disparities in exposure to firearm violence and contextualize them ethnographically in the lived experience of community members. The exceptionally concentrated and high-volume retail narcotics trade, and the violence it generates in Philadelphia's poor Puerto Rican neighborhoods, reflect unique structural vulnerability and cultural factors. For most young people in these areas, the narcotics economy is the most readily accessible form of employment and social mobility. The performance of violence is an implicit part of survival in these lucrative, illegal narcotics markets, as well as in the overcrowded jails and prisons through which entry-level sellers cycle chronically. To address the structural drivers of violence, an inner-city Marshall Plan is needed that should include well-funded formal employment programs, gun control, re-training police officers to curb the routinization of brutality, reform of criminal justice to prioritize rehabilitation over punishment, and decriminalization of narcotics possession and low-level sales.

Assessment of Racial/Ethnic and Income Disparities in the Prescription of Opioids and Other Controlled Medications in California

Importance

Most drug epidemics in the United States have disproportionately affected nonwhite communities. Notably, the current opioid epidemic is heavily concentrated among low-income white communities, and the roots of this racial/ethnic phenomenon have not been adequately explained.

Objective

To examine the degree to which differential exposure to opioids via the health care system by race/ethnicity and income could be driving the observed social gradient of the current opioid epidemic, as well as to compare the trends in the prevalence of prescription opioids with those observed for stimulants and benzodiazepines.

Design, Setting, and Participants

This population-based study used 2011 through 2015 records from California's prescription drug monitoring program (Controlled Substance Utilization Review and Evaluation System), which longitudinally tracks all patients receiving controlled substance prescriptions in the state and contained unique records for 29.7 million individuals who received such a prescription from 2011 to 2015. Data were analyzed between January and May 2018.

Exposures

A total of 1760 zip code tabulation areas (ZCTAs) in California, with associated racial/ethnic composition and per capita income.

Main Outcomes and Measures

The percentage of individuals receiving at least 1 prescription each year was calculated for opioids, benzodiazepines, and stimulants.

Results

A nearly 300% difference in opioid prescription prevalence across the race/ethnicity-income gradient was observed in California, with 44.2% of adults in the quintile of ZCTAs with the lowest-income/highest proportion-white population receiving at least 1 opioid prescription each year compared with 16.1% in the quintile with the highest-income/lowest proportion-white population and 23.6% of all individuals 15 years or older. Stimulant prescriptions were highly concentrated in mostly white high-income areas, with a prevalence of 3.8% among individuals in the quintile with the highest-income/highest proportion-white population and a prevalence of 0.6% in the quintile with the lowest-income/lowest proportion-white population. Benzodiazepine prescriptions did not have an income gradient but were concentrated in mostly white areas, with 15.7% of adults in the quintile of ZCTAs with the highest proportion-white population receiving at least 1 prescription each year compared with 7.0% among the quintile with the lowest proportion-white population.

Conclusions and Relevance

The race/ethnicity and income pattern of opioid overdoses mirrored prescription rates, suggesting that differential exposure to opioids via the health care system may have induced the large, observed racial/ethnic gradient in the opioid epidemic. Across drug categories, controlled medications were much more likely to be prescribed to individuals living in majority-white areas. These discrepancies may have shielded nonwhite communities from the brunt of the prescription opioid epidemic but also represent disparities in treatment and access to all medications.

My Child's Journey Home: Perspectives of Adult Family Members on the Separation and Reunification of the "Disappeared" Children of El Salvador

This article explores family separation and reunification of the disappeared Salvadoran children separated from their families during El Salvador's civil war (1980-1992) from the perspectives of adult relatives. During separation, adult relatives experienced an "unresolvable loss." Following reunion, families experienced an immediate relief that was often accompanied by an "ambiguous reunification." Emotions were especially complicated and painful when the separation had been a "forced choice" by the parent under coercive wartime political conditions. Adoptive parents strongly influenced reunification. Findings suggest that disappeared children and biological and adoptive family members need psycho-social support throughout separation and reunification.

The Structural Violence of Hyperincarceration - A 44-Year-Old Man with Back Pain

Mr. M., an uninsured, 44-year-old Puerto Rican man with chronic back pain, diabetes, hypertension, asthma, and a history of incarceration presented to a free clinic with acute exacerbation of back pain triggered by carrying heavy loads of trash at work. A premedical student acting as his health care advocate accompanied him. Mr. M. was hesitant to seek health care because he had no health insurance and mistrusted institutions as a result of his extensive negative experiences with the criminal justice system. He was visibly nervous in the unfamiliar institutional environment of the clinic, which had no Latino staff and was located in a middle-class neighborhood far from his home. The advocate reassured him in Spanish that the doctor was trustworthy and urged him to speak frankly about his health problems, including his challenges in obtaining medication. Embarrassed, Mr. M. reported that during recent back-pain exacerbations he occasionally resorted to purchasing one or two 5-mg oxycodone tablets in the open-air drug market operating on the inner-city block where he lived. The physician gave Mr. M. ibuprofen and a prescription for five 5-mg oxycodone tablets, enrolled him in the clinic’s diabetes and hypertension programs, and scheduled a follow-up visit. Mr. M. never filled the prescription and did not return to the clinic, despite repeated entreaties by the advocate both in person and over the phone. Mr. M.’s pain had eased, and he claimed to be managing his diabetes, hypertension, and asthma by splitting medication with insured family members. To stretch their supply, they rationed their doses for use only on the days when they “felt symptoms.” Finally, 8 months later, Mr. M. admitted that he had not dared fill his prescription or return to the clinic for fear of being rearrested after admitting to the doctor that he had purchased oxycodone illegally.

Differences in time to injection onset by drug in California: Implications for the emerging heroin epidemic

BACKGROUND

Heroin use is increasing in the US. Heroin use may predispose users towards injection routes of drug administration as compared to other illicit substances.

OBJECTIVE

To explore the relationship between heroin use and drug injection, we compared time from first use to first injection (referred to as time to injection onset by drug [TTIOD]) of heroin, methamphetamine/speed, cocaine, and crack cocaine among people who inject drugs (PWID).

METHODS

Age of first use and first injection by drug was collected from 776 PWID. Survival analyses were used to determine TTIOD and to examine demographic factors associated with TTIOD. Cox regression analysis was used to determine demographic factors associated with drug-specific injection onset.

RESULTS

The eventual injection onset rate by the drug was 99% for participants who used heroin, 85% for participants who used methamphetamine/speed, 80% for participants who used powder cocaine, and 38% for participants who used crack cocaine. Hazard ratios for injection use within one year of first use by drug were: 1.37 (median survival time [MST] = 0.61 years) for heroin, 0.66 (MST = 1.10 years) for methamphetamine/speed, 0.50 (MST = 2.93 years) for powder cocaine, and 0.12 (MST = 39.59 years) for crack cocaine. Demographic differences in TTIOD were found for each drug. Demographic differences were found for eventual injection by drug for all substances except heroin.

CONCLUSION

Among PWID, heroin use was associated with a more rapid transition to injection and a higher rate of eventual heroin injection regardless of demographics. More robust, innovative efforts to reduce heroin use and prevent injection initiation are urgently needed.

Decolonising drug studies in an era of predatory accumulation

The cultural and political-economic valences of psychoactive drugs in the Global South offer critical insights on local and international fault lines of social inequality and profiteering. Historically, in a classic primitive accumulation process the trafficking of industrially produced euphoric substances across the globe have wreaked havoc among vulnerable populations while extracting profit for the powerful. The complex flows of capital generated both by illegal addiction markets and also by the mobilisation of licit public funds to manage their mayhem, however, suggest the contemporary utility of the concept of 'predatory accumulation'. The Enlightenmentera concept of 'primitive accumulation' usefully highlighted state violence and forcible dispossession in the consolidation of European capitalism. A contemporary reframing of these processes as predatory accumulation, however, highlights contradictory, nonlinear relationships between the artificially high profits of illegal drug sales, repressive governmentality and corporate greed. It sets these patterns of destructive profiteering in the context of our moment in history.

Drug use generations and patterns of injection drug use: Birth cohort differences among people who inject drugs in Los Angeles and San Francisco, California

OBJECTIVES

A robust literature documents generational trends in drug use. We examined the implications of changing national drug use patterns on drug injection histories of diverse people who inject drugs (PWID).

METHODS

Drug use histories were collected from 776 active PWID in 2011-13. Using descriptive statistics, we examine drug use initiation by year and birth cohort (BC) differences in drug first injected. A multivariate linear regression model of time to injection initiation ([TTII] (year of first injection minus year of first illicit drug use) was developed to explore BC differences.

RESULTS

The first drug injected by BC changed in tandem with national drug use trends with heroin declining from 77% for the pre-1960's BC to 58% for the 1960's BC before increasing to 71% for the 1990's BC. Multivariate linear regression modeling found that shorter TTII was associated with the 1980's/1990's BC (-3.50 years; 95% Confidence Interval [CI]=-0.79, -6.21) as compared to the 1970's BC. Longer TTII was associated with being female (1.65 years; 95% CI=0.40, 2.90), African American (1.69 years; 95% CI=0.43, 2.95), any substance use treatment prior to injection (4.22 years; 95% CI=2.65, 5.79), and prior non-injection use of drug that was first injected (3.29 years; 95% CI=2.19, 4.40).

CONCLUSION

National drug trends appear to influence injection drug use patterns. The prescription opiate drug era is associated with shorter TTII. Culturally competent, demographically and generationally-targeted prevention strategies to combat transitions to drug injection are needed to prevent or shorten upstream increases in risky drug use practices on a national level.

Structural Vulnerability: Operationalizing the Concept to Address Health Disparities in Clinical Care

The authors propose reinvigorating and extending the traditional social history beyond its narrow range of risk behaviors to enable clinicians to address negative health outcomes imposed by social determinants of health. In this Perspective, they outline a novel, practical medical vulnerability assessment questionnaire that operationalizes for clinical practice the social science concept of "structural vulnerability." A structural vulnerability assessment tool designed to highlight the pathways through which specific local hierarchies and broader sets of power relationships exacerbate individual patients' health problems is presented to help clinicians identify patients likely to benefit from additional multidisciplinary health and social services. To illustrate how the tool could be implemented in time- and resource-limited settings (e.g., emergency department), the authors contrast two cases of structurally vulnerable patients with differing outcomes. Operationalizing structural vulnerability in clinical practice and introducing it in medical education can help health care practitioners think more clearly, critically, and practically about the ways social structures make people sick. Use of the assessment tool could promote "structural competency," a potential new medical education priority, to improve understanding of how social conditions and practical logistics undermine the capacities of patients to access health care, adhere to treatment, and modify lifestyles successfully. Adoption of a structural vulnerability framework in health care could also justify the mobilization of resources inside and outside clinical settings to improve a patient's immediate access to care and long-term health outcomes. Ultimately, the concept may orient health care providers toward policy leadership to reduce health disparities and foster health equity.

The Textures of Heroin: User Perspectives on "Black Tar" and Powder Heroin in Two U.S. Cities

Since the 1990s, U.S. heroin consumers have been divided from the full range of available products: east of the Mississippi River, Colombian-sourced powder heroin (PH) dominates the market while, to the west, Mexican-sourced "black tar" (BTH) is the main heroin available. By conducting qualitative research in two exemplar cities, Philadelphia (PH) and San Francisco (BTH), we compare users' experiences of heroin source-types, markets, health consequences, and consumption preferences. The strict division of heroin markets may be changing with novel forms of powder heroin appearing in San Francisco. Our researchers and interviewees perceived vein loss stemming from the injection of heroin alone to be a particular problem of BTH while, among the Philadelphia sample, those who avoided the temptations of nearby cocaine sales displayed healthier injecting sites and reported few vein problems. Abscesses were common across both sites, the Philadelphia sample generally blaming missing a vein when injecting cocaine and the San Francisco group finding several explanations, including the properties of BTH. Consumption preferences revealed a "connoisseurship of potency," with knowledge amassed and deployed to obtain the strongest heroin available. We discuss the reasons that their tastes take this narrow form and its relationship to the structural constraints of the heroin market.

Injecting drugs in tight spaces: HIV, cocaine and collinearity in the Downtown Eastside, Vancouver, Canada

This commentary revisits the political turmoil and scientific controversy over epidemiological study findings linking high HIV seroincidence to syringe exchange attendance in Vancouver in the mid-1990s. The association was mobilized polemically by US politicians and hard-line drug warriors to attack needle exchange policies and funding. In turn, program restrictions limiting access to syringes at the Vancouver exchange may have interfaced with a complex conjunction of historical, geographic, political economic and cultural forces and physiological vulnerabilities to create an extraordinary HIV risk environment: (1) ghettoization of services for indigent populations in a rapidly gentrifying, post-industrial city; (2) rural-urban migration of vulnerable populations subject to historical colonization and current patterns of racism; and (3) the flooding of North America with inexpensive powder cocaine and heroin, and the popularity of crack. In fact, we will never know with certainty the precise cause for the extreme seroincidence rates in Vancouver in the early to mid-1990s. The tendency for modern social epidemiology to decontextualize research subjects and assign excessive importance to discrete, "magic bullet" variables resulted in a counterproductive scientific and political debate in the late 1990s that has obfuscated potentially useful practical lessons for organizing the logistics of harm reduction services - especially syringe exchange - to better serve the needs of vulnerable populations and to mitigate the effects of political-economically imposed HIV risk environments. We would benefit from humbly acknowledging the limits of public health science and learn to recognize the unintended consequences of well-intentioned interventions rather than sweep embarrassing histories under the rug.

[Pax Narcotica : The Open-Air Drug Markets of Philadelphia's Puerto Rican Inner City]

Fondé sur un travail de terrain mené pendant cinq ans dans le ghetto portoricain de Philadelphie, cet article explore les logiques de violence et de paix à l’œuvre dans ce secteur situé en fin de circuit de l’industrie globale du narcotrafic. Tout en recourant à la violence armée pour éliminer leurs rivaux et défendre leur territoire, les patrons locaux de la drogue doivent simultanément renvoyer l’image de figures généreuses pour éviter que les habitants ne les dénoncent à la police, en se montrant responsables, prêts à redistribuer les ressources, à offrir des emplois bien rémunérés, à discipliner leurs employés et à contenir les excès de violence. Les chefs de la drogue sont donc contraints de transformer leur force brute en un pouvoir vertueux pour prospérer. Ils participent ainsi, avec voisins et employés, à une économie morale de relations patrimoniales et clientélistes au sein de laquelle ils s’imposent comme des leaders charismatiques. À partir d’une relecture du concept d’ « accumulation primitive », cet article revient à la fois : 1) sur la relation coloniale qui pousse la diaspora portoricaine ghettoïsée dans la niche économique que représente la revente de drogue au détail; 2) sur la violence symbolique à l’œuvre à tous les échelons de ce trafic; 3) sur les profits artificiellement élevés générés par cette industrie criminalisée par l’État; 4) et sur la prolifération opportuniste de secteurs spécialisés de l’économie légale et de la bureaucratie publique chargés de gérer les effets collatéraux de la coercition et des violences d’État.

Heroin-related overdose: The unexplored influences of markets, marketing and source-types in the United States

Heroin overdose, more accurately termed 'heroin-related overdose' due to the frequent involvement of other drugs, is the leading cause of mortality among regular heroin users. (Degenhardt et al., 2010) Heroin injectors are at greater risk of hospital admission for heroin-related overdose (HOD) in the eastern United States where Colombian-sourced powder heroin is sold than in the western US where black 'tar' heroin predominates. (Unick et al., 2014) This paper examines under-researched influences on HOD, both fatal and non-fatal, using data from a qualitative study of injecting drug users of black tar heroin in San Francisco and powder heroin in Philadelphia Data were collected through in-depth, semi-structured interviews carried out in 2012 that were conducted against a background of longer-term participant-observation, ethnographic studies of drug users and dealers in Philadelphia (2007-12) and of users in San Francisco (1994-2007, 2012). Our findings suggest three types of previously unconsidered influences on overdose risk that arise both from structural socio-economic factors and from the physical properties of the heroin source-types: 1) retail market structure including information flow between users; 2) marketing techniques such as branding, free samples and pricing and 3) differences in the physical characteristics of the two major heroin source forms and how they affect injecting techniques and vascular health. Although chosen for their contrasting source-forms, we found that the two cities have contrasting dominant models of drug retailing: San Francisco respondents tended to buy through private dealers and Philadelphia respondents frequented an open-air street market where heroin is branded and free samples are distributed, although each city included both types of drug sales. These market structures and marketing techniques shape the availability of information regarding heroin potency and its dissemination among users who tend to seek out the strongest heroin available on a given day. The physical characteristics of these two source-types, the way they are prepared for injecting and their effects on vein health also differ markedly. The purpose of this paper is to examine some of the unexplored factors that may lead to heroin-related overdose in the United States and to generate hypotheses for further study.

Examining the associations between sex trade involvement, rape, and symptomatology of sexual abuse trauma

The high prevalence of rape and sexual trauma symptomatology among women involved in street-based sex trades is well-established. Because prior research has lacked appropriate, non-sex trade involved comparison groups, it is unknown whether differences exist among similarly situated women who do and do not trade sex. This article explores experiences of childhood and adult rape and symptomatology of sexual abuse trauma among a community-based sample of 322 women who use methamphetamine in San Francisco, California, 61% of whom were involved in the sex trade. Study participants were recruited via respondent-driven sampling and eligible if they were cisgender women, aged 18 or older, current methamphetamine users, and sexually active with at least one cisgender man in the past 6 months. The dependent variable was sexual abuse trauma symptomatology, as measured by the Sexual Abuse Trauma Index (SATI) subscale of the Trauma Symptom Checklist-40 (TSC-40), and the explanatory variable was sex trade involvement. Potential covariates were age, current homelessness, methamphetamine dependence, and experiences of childhood and adult rape. Sixty-one percent of participants had a SATI subscale score suggestive of sexual abuse trauma. The overall prevalence of rape in childhood and adulthood was 52% and 73%, respectively. In bivariate analysis, sex trade involvement and all of the potential covariates except for homelessness and age were associated with a SATI score suggestive of sexual abuse trauma. In multivariate models controlling for significant covariates, there was no longer a statistically significant association between sex trade involvement or childhood rape and an elevated SATI score. Elevated levels of psychological dependence on methamphetamine and experiences of rape as an adult were still associated with a high SATI score. These findings highlight that urban poor women, regardless of sex trade involvement, suffer high levels of rape and related trauma symptomatology.

Non-partner violence against women who use drugs in San Francisco

This article examines non-partner violence among women who use methamphetamine (N = 322), recruited in an inner-city neighborhood of San Francisco. The combined prevalence of non-partner physical or sexual violence in the past 6 months was 28%, roughly equal to the prevalence of partner violence (26%). In multivariate analysis, factors associated with non-partner violence included frequent subsistence difficulty (adjusted odds ratio [AOR] = 2.43, 95% confidence interval [CI] = [1.3, 4.6]) and sex trade (AOR = 2.27, 95% CI = [1.4, 4.1]). Having a steady male partner was not protective against non-partner violence. Violence perpetrated by non-partners should be considered when assessing social and structural factors that influence women's health.

Urban segregation and the US heroin market: a quantitative model of anthropological hypotheses from an inner-city drug market

BACKGROUND

We hypothesize that the location of highly segregated Hispanic and in particular Puerto Rican neighborhoods can explain how Colombian-sourced heroin, which is associated with a large-scale decade long decline in heroin price and increase in purity, was able to enter and proliferate in the US.

METHODS

Our multidisciplinary analysis quantitatively operationalizes participant-observation ethnographic hypotheses informed by social science theory addressing complex political economic, historical, cultural and social processes. First, we ethnographically document the intersection of structural forces shaping Philadelphia's hypersegregated Puerto Rican community as a regional epicenter of the US heroin market. Second, we estimate the relationship between segregation and: (a) the entry of Colombian heroin into the US, and (b) the retail price per pure gram of heroin in 21 Metropolitan Statistical Areas.

RESULTS

Ethnographic evidence documents how poverty, historically-patterned antagonistic race relations, an interstitial socio-cultural political and geographic linkage to both Caribbean drug trafficking routes and the United States and kinship solidarities combine to position poor Puerto Rican neighborhoods as commercial distribution centers for high quality, low cost Colombian heroin. Quantitative analysis shows that heroin markets in cities with highly segregated Puerto Rican communities were more quickly saturated with Colombian-sourced heroin. The level of Hispanic segregation (specifically in cities with a high level of Puerto Rican segregation) had a significant negative association with heroin price from 1990 to 2000. By contrast, there is no correlation between African-American segregation and Colombian-sourced heroin prevalence or price.

CONCLUSION

Our iterative mixed methods dialogue allows for the development and testing of complex social science hypotheses and reduces the limitations specific to each method used in isolation. We build on prior research that assumes geographic proximity to source countries is the most important factor in determining illicit drug prices and purity, while we find more complex, potentially modifiable determinants of geographic variation in retail drug markets. We show that specific patterns of ethnic segregation, racism, poverty and the political economy of socio-cultural survival strategies combined to facilitate the entry of pure, inexpensive Colombian-sourced heroin.

"Every 'never' I ever said came true": transitions from opioid pills to heroin injecting

This qualitative study documents the pathways to injecting heroin by users in Philadelphia and San Francisco before and during a pharmaceutical opioid pill epidemic. Data was collected through in-depth, semi-structured interviews (conducted between 2010 and 2012) that were, conducted against a background of longer-term participant-observation, ethnographic studies of street-based drug users and dealers in Philadelphia (2007-12) and San Francisco (1994-2007, 2012). Philadelphia and San Francisco were selected for their contrasting political economies, immigration patterns and source type of heroin. In Philadelphia the ethnographers found heroin injectors, usually white users, who had started their opiate using careers with prescription opioids rather than transitioning from other drugs. In both Philadelphia and San Francisco, most of the young heroin injectors interviewed began, their drug-use trajectories with opioid pills--usually Percocet (oxycodone and acetaminophen), generic short acting oxycodone or, OxyContin (long-acting oxycodone)--before transitioning to heroin, usually by nasal inhalation (sniffing) or smoking at first, followed by injecting. While most of the Philadelphia users were born in the city or its suburbs and had started using both opioid pills and heroin there, many of the San Francisco users had initiated their pill and sometimes heroin use elsewhere and had migrated to the city from around the country. Nevertheless, patterns of transition of younger injectors were similar in both cities suggesting an evolving national pattern. In contrast, older users in both Philadelphia and San Francisco were more likely to have graduated to heroin injection from non-opiate drugs such as cannabis, methamphetamine and cocaine. Pharmaceutical opioid initiates typically reported switching to heroin for reasons of cost and ease-of-access to supply after becoming physically and emotionally dependent on opioid pills. Many expressed surprise and dismay at their progression to sniffing and subsequently to injecting heroin. Historically and structurally these users found themselves caught at the intersection of two major developments in the opiate supply: (1) an over 500% increase in opiate pill prescription from 1997 to 2005 resulting in easy access to diverted supplies of less stigmatized opiates than heroin and (2) a heroin supply glut, following the US entry of Colombian-sourced, heroin in the early 1990s, that decreased cost and increased purity at the retail level. A nationwide up-cycle of heroin use may be occurring among young inner city, suburban and rural youth fueled by widespread prescription opioid pill use.

Pathologizing poverty: new forms of diagnosis, disability, and structural stigma under welfare reform

In 1996 the U.S. severely restricted public support for low income people, ending "welfare as we know it." This led to dramatic increases in medicalized forms of support for indigent people, who increasingly rely on disability benefits justified by psychiatric diagnoses of chronic mental illness. We present case studies drawn from ethnographic data involving daily participant-observation between 2005 and 2012 in public clinics and impoverished neighborhoods in New York City, to describe the subjective experience of structural stigma imposed by the increasing medicalization of public support for the poor through a diagnosis of permanent mental disability. In some cases, disability benefits enable recipients to fulfill important social roles (sustaining a vulnerable household and promoting stable parenting). The status of family members who receive a monthly disability check improves within their kin and neighborhood-based networks, counterbalancing the felt stigma of being identified by doctors as "crazy". When a diagnosis of mental pathology becomes a valuable survival strategy constituting the basis for fulfillment of household responsibilities, stigmatizing processes are structurally altered. Through the decades, the stigmatized labels applied to the poor have shifted: from being a symptom of racial weakness, to the culture of poverty, and now to permanent medical pathology. The neoliberal bureaucratic requirement that the poor must repeatedly prove their "disabled" status through therapy and psychotropic medication appears to be generating a national and policy-maker discourse condemning SSI malingerers, resurrecting the 16th century specter of the "unworthy poor".

The Moral Economy of Violence in the US Inner City

In an 8-week period, there were 16 shootings with three fatalities, three stabbings, and 14 additional "aggravated assaults" in the four square blocks surrounding our field site in the Puerto Rican corner of North Philadelphia. In the aftermath of the shoot-outs, the drug sellers operating on our block were forced to close down their operations by several mothers who repeatedly called the police. Drawing on the concept of moral economy (Thompson, Scott, Taussig), Mauss's interpretation of gift exchange, and a political economy critique of hypercarceralization in the United States, we understand the high levels of US inner-city violence as operating within a moral logic framed by economic scarcity and hostile state relations. Residents seek security, self-respect, and profit in social networks that compel them to participate in solidary exchanges of assistive violence dynamized by kinship and gender obligations. A hierarchical, extractive drug economy fills the void left by deindustrialization, resulting in a dynamic of embodied primitive accumulation at the expense of addicted customers and chronically incarcerated just-in-time street sellers at high risk of assault. Nevertheless, the mobilization of violence organizing the illegal drug economy also follows ethical norms and obligations that are recognized as legitimate by many local residents.

The good-enough science-and-politics of anthropological collaboration with evidence-based clinical research: Four ethnographic case studies

The apolitical legitimacy of "evidence-based medicine" offers a practical means for ethnography and critical social-science-and-humanities-of-health theory to transfer survival resources to structurally vulnerable populations and to engage policy and services audiences with urgent political problems imposed on the urban poor in the United States that harm health: most notably, homelessness, hyperincarceration, social service cut-backs and the War on Drugs. We present four examples of collaborations between ethnography and clinical research projects that demonstrate the potentials and limits of promoting institutional reform, political debate and action through distinct strategies of cross-methodological dialog with epidemiological and clinical services research. Ethnographic methods alone, however, are simply a technocratic add-on. They must be informed by critical theory to contribute effectively and transformatively to applied health initiatives. Ironically, technocratic, neoliberal logics of cost-effectiveness can sometimes render radical service and policy reform initiatives institutionally credible, fundable and capable of generating wider political support, even though the rhetoric of economic efficacy is a double-edged sword. To extend the impact of ethnography and interdisciplinary theories of political-economic, cultural and disciplinary power relations into applied clinical and public health research, anthropologists - and their fellow travelers - have to be able to strategically, but respectfully learn to see through the positivist logics of clinical services research as well as epidemiological epistemology in order to help clinicians achieve - and extend - their applied priorities. In retrospect, these four very differently-structured collaborations suggest the potential for "good-enough" humble scientific and political strategies to work for, and with, structurally vulnerable populations in a punitive neoliberal era of rising social inequality, cutbacks of survival services, and hyperincarceration of the poor.

Low-frequency heroin injection among out-of-treatment, street-recruited injection drug users

In this paper, we explore the understudied phenomenon of "low-frequency" heroin injection in a sample of street-recruited heroin injectors not in drug treatment. We conducted a cross-sectional study of 2,410 active injection drug users (IDUs) recruited in San Francisco, California from 2000 to 2005. We compare the sociodemographic characteristics and injection risk behaviors of low-frequency heroin injectors (low-FHI; one to 10 self-reported heroin injections in the past 30 days) to high-frequency heroin injectors (high-FHI; 30 or more self-reported heroin injections in the past 30 days). Fifteen percent of the sample met criteria for low-FHI. African American race, men who have sex with men (MSM) behavior, and injection and noninjection methamphetamine use were independently associated with low-FHI. Compared to high-FHI, low-FHI were less likely to report syringe sharing and nonfatal heroin overdose. A small but significant proportion of heroin injectors inject heroin 10 or less times per month. Additional research is needed to qualitatively examine low-frequency heroin injection and its relationship to drug use trajectories.

[The Habit of Rage in a United States Ghetto.]

For five years, the open air drug sales block where the authors resided and conducted participant-observation fieldwork in the Puerto Rican corner of inner-city Philadelphia was subject to a routinized whirlwind of shootings, stabbings and assaults. The narcotics industry filled the void left by deindustrialization, turning the city's former factory district into an open-air narcotics supermarket staffed at the entry level by young Puerto Ricans serving primarily poor white injectors. A capacity to mobilize rage ensures success in the drug economy, protection in prison, and minimal income for the no-longer-worthy poor who are diagnosed as cognitively disabled. Many residents seek alliances in social networks that oblige them to participate in solidary exchanges of assistive violence. A dynamic of embodied, primitive accumulation kills, maims, disables or incarcerates most of this industry's entry-level employees and customers. Artificially high profit margins depend on violence and coercion. A rage-filled habitus propels street-level sellers into violently defending the micro-monopoly power of their bosses in the underground economy as if it were fun. They rush to enforce commercial transactions in the absence of protective legal sanctions in an environment of scarcity that is flooded by streams of cash, addictive drugs and automatic weapons. With the end of welfare entitlements, the left hand of the state, in the form of social services, attempts to continue subsidies for vulnerable individuals by diagnosing scarred bodies and brains as proof of permanent cognitive disability in need of heavy pharmaceutical medication. Periodic outbursts of interpersonal or of self-inflicted rage-filled violence emerge as the best way to ensure the continuity of that fragile public subsidy. Simultaneously, within the bowels of the right hand of the state, in overcrowded, hostilely-supervised violent prisons, rage becomes a valuable physical self-protection strategy for inmates. In short, expressive violence becomes a practical basis for economic sustenance and masculine and feminine self respect.

Sexual pleasure and sexual risk among women who use methamphetamine: a mixed methods study

BACKGROUND

The intersection of drug use, sexual pleasure and sexual risk behaviour is rarely explored when it comes to poor women who use drugs. This paper explores the relationship between sexual behaviour and methamphetamine use in a community-based sample of women, exploring not only risk, but also desire, pleasure and the challenges of overcoming trauma.

METHODS

Quantitative data were collected using standard epidemiological methods (N=322) for community-based studies. In addition, using purposive sampling, qualitative data were collected among a subset of participants (n=34). Data were integrated for mixed methods analysis.

RESULTS

While many participants reported sexual risk behaviour (unprotected vaginal or anal intercourse) in the quantitative survey, sexual risk was not the central narrative pertaining to sexual behaviour and methamphetamine use in qualitative findings. Rather, desire, pleasure and disinhibition arose as central themes. Women described feelings of power and agency related to sexual behaviour while high on methamphetamine. Findings were mixed on whether methamphetamine use increased sexual risk behaviour.

CONCLUSION

The use of mixed methods afforded important insights into the sexual behaviour and priorities of methamphetamine-using women. Efforts to reduce sexual risk should recognize and valorize the positive aspects of methamphetamine use for some women, building on positive feelings of power and agency as an approach to harm minimization.

Bringing HIV, Substance Abuse and Homelessness into the University of Pennsylvania Anthropology Museum through Photo-Ethnography

In the fall of 1994 I befriended a community of some two dozen heroin injectors and crack smokers surviving under the overpasses of a tangle of freeways six blocks from where I lived in San Francisco. The full force of the Reagan-era cutbacks from the 1980s had trickled down to the street, shredding the already rachitic U.S. welfare safety-net. Inner-cities were gentrifying (especially those linked to the epicenters of global finance capital such as San Francisco). The former skid row habitat for the unstable urban poor-cheap single-residency hotels-was being converted into multi-million dollar condominiums. Urban police forces had not yet systematized, routinized and replicated their zero-tolerance enforcement, harassment/incarceration dragnets (Wacquant 2009) and homelessness, consequently, was at its most visible. Bourgeois residents like me could not walk down a block or drive up a freeway entrance ramp in downtown San Francisco without being solicited for spare change. I obtained a National Institutes of Health HIV prevention grant and for the next 12 years, together with a photographer/anthropologist collaborator Jeff Schonberg and several additional ethnographic team members, we followed the social network of homeless addicts surviving in my neighborhood, documenting the unhealthy effects of indigence and substance abuse.

Théoriser la violence en Améerique: Retour sur trente ans d'ethnographie

PHILIPPE BOURGOIS THEORIZING VIOLENCE IN THE AMERICAS A THIRTY-YEAR ETHNOGRAPHIC RETROSPECTIVE

This thirty year retrospective analysis of violence at my fieldwork sites in the Americas (Nicaragua, El Salvador, Costa Rica, Panama, USA) explores the importance and difficulty of recognizing the continuities of violence across historical eras as an ethnographer. Expanding on the continuum of violence concept, I propose the utility of identifying the mutually reinforcing interface of three overlapping categories of invisible violence: structural, symbolic and normalized. If theory is meant to help us see more, then theorizing violence through a continuum of categories of invisibility is useful because it contravenes the political effects of the contemporary hyper-visibility of interpersonal and petty criminal street violence. The increasing global reach of a punitive version of corporate neoliberalism over the past two decades has lumpenized large sectors of the urban and rural poor. Recognizing the links between categories of invisible violence in this globalized context of social inequality explains the demobilization of class-based demands for economic redistribution and populist support for physically repressive forms of governmentality that punish the poor deemed unworthy.

Structural vulnerability and health: Latino migrant laborers in the United States

Latino immigrants in the United States constitute a paradigmatic case of a population group subject to structural violence. Their subordinated location in the global economy and their culturally depreciated status in the United States are exacerbated by legal persecution. Medical Anthropology, Volume 30, Numbers 4 and 5, include a series of ethnographic analyses of the processes that render undocumented Latino immigrants structurally vulnerable to ill health. We hope to extend the social science concept of "structural vulnerability" to make it a useful concept for health care. Defined as a positionality that imposes physical/emotional suffering on specific population groups and individuals in patterned ways, structural vulnerability is a product of class-based economic exploitation and cultural, gender/sexual, and racialized discrimination, as well as complementary processes of depreciated subjectivity formation. A good-enough medicalized recognition of the condition of structural vulnerability offers a tool for developing practical therapeutic resources. It also facilitates political alternatives to the punitive neoliberal policies and discourses of individual unworthiness that have become increasingly dominant in the United States since the 1980s.

Education, empowerment and community based structural reinforcement: an HIV prevention response to mass incarceration and removal

In the context of US urban jails, incarceration is often seen as an opportune intervention point for prevention interventions in public health. For the detained individual, it is an opportunity to reflect on individual choices and the potential for changes in one's life course. For population focused public health professionals, jail detention facilities represent a concentration of health risks, and an opportunity to have an impact on a significant portion of those at risk for HIV and other health concerns. This paper presents an innovative education and empowerment model that bridges across jail walls, beginning on the inside, and continuing on the outside of jail where individuals continue to be challenged and supported toward positive health and social choices. The intervention also seeks to foment community activism in the communities to which jail detainees return, thus aiming to have a structural impact. This paper examines both the intervention model and the challenges of examining the effectiveness claims for the intervention at multiple levels.

Lumpen Abuse: The Human Cost of Righteous Neoliberalism

I thank the Society for Urban Anthropology for the Anthony Leeds Book Prize. The award gives me special pleasure because I think of myself primarily as an urban anthropologist. I was trained in "peasant studies" as a student of Eric Wolf's in the late 1970s and early 1980s eager to conduct participant-observation fieldwork on the revolutionary movements taking place in Central America in those decades. It was a hopeful - even inspiring - moment in history at my doctoral fieldwork theme/sites: the agrarian reform in the Amerindian Moskitia territory of Sandinista Nicaragua (1979-80, 1984), guerrilla warfare in an FMLN-controlled territory in El Salvador (1981), and farmworker organizing on a United Fruit Company plantation enclave spanning the Costa Rica/Panama Caribbean border (1982-1984). During these exciting years of fieldwork, however, I found myself longing to return to my hometown to conduct ethnography on the same themes that I was witnessing in the countryside of Central America: the political mobilization/demobilization of class struggle in the context of racialized ethnicity and extreme social inequality. Consequently, while writing up my dissertation (Bourgois 1989), I moved to East Harlem two dozen blocks from where I had grown up in New York City to document what I came to call "US inner-city apartheid." That was in March of 1985 and ever since, my work has been primarily dedicated to understanding urban social inequality.

Drug use patterns in the presence of crack in downtown Montréal

INTRODUCTION AND AIMS

A study was undertaken to verify reports of an increasing presence of crack in downtown Montréal, and to investigate the influence of crack availability on current drug use patterns among street-based cocaine users.

DESIGN AND METHODS

The study combined both qualitative and quantitative methods. These included long-term intensive participant observation carried out by an ethnographer familiar with the field and a survey. The ethnographic component involved observations and unstructured interviews with 64 street-based cocaine users. Sampling was based on a combination of snowballing and purposeful recruitment methods. For the survey, structured interviews were conducted with a convenience sample of 387 cocaine users attending HIV/HCV prevention programs, downtown Montréal.

RESULTS

A gradual shift has occurred in the last 10 years, with the crack street market overtaking the powder cocaine street market. Although the data pointed to an increase in crack smoking, 54.5% of survey participants both smoked and injected cocaine. Drug market forces were major contributing factors to the observed modes of cocaine consumption. While the study focused primarily on cocaine users, it became apparent from the ethnographic fieldwork that prescription opioids (POs) were very present on the streets. According to the survey, 52.7% of participants consumed opioids, essentially POs, with 88% of them injecting these drugs.

DISCUSSION AND CONCLUSIONS

Despite the increased availability of crack, injection is still present among cocaine users due at least in part to the concurrent increasing popularity of POs.

The challenge of pregnancy among homeless youth: reclaiming a lost opportunity

Young, homeless women often become pregnant, but little is known about how street youth experience their pregnancies. We documented 26 pregnancy outcomes among 13 homeless women (ages 18-26) and eight homeless men through interviews and participant-observation. Eight pregnancies were voluntarily terminated, three were miscarried, and fifteen were carried to term. Regardless of pregnancy outcome, street youths' narratives focused on ambivalence about parenting, traumatic childhood experiences, and current challenges. Despite significant obstacles, almost all were convinced of their personal capacity to change their lives. While most wanted to be parents, the majority lost custody of their newborns and consequently associated contact with medical and social services with punitive outcomes. Most of the youth who chose to terminate successfully sought safe medical care. We offer recommendations for changing the approach of services to take full advantage of pregnancy as a potential catalyst event for change in this highly vulnerable and underserved population.
