Decrease in injection and rise in smoking and snorting of heroin and synthetic opioids, 2000-2021.

Background: Injecting, smoking, and snorting heroin/synthetic opioids is each associated with unique health risks. It is unclear how route of administration (ROA) preferences have shifted during the opioid epidemic.

Methods: Using 2000-2021 admissions data from SAMHSA TEDS-A, we analyzed trends in heroin/synthetic opioid ROA preferences and factors associated with these preferences.

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.

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.

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.

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.

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.

[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.

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.

"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.

Methuselah's medicine: pharmaceutical innovation and mortality in the United States, 1960-2000.

Although there is a good deal of speculation surrounding the role of pharmaceutical innovation in late 20th century mortality improvements in the United States, there is little empirical evidence on the topic and there remains a good deal of doubt regarding whether pharmaceuticals matter at all for mortality. Using a reliable indicator of pharmaceutical innovation-yearly approvals of new molecular entities (NMEs) by the Food and Drug Administration, along with information on priority status and disease-category indication-this study examines the relationship between pharmaceutical innovation and life expectancy between 1960 and 2000. The study demonstrates a significant relationship between pharmaceutical innovation and life expectancy at birth, which is robust to controls for gross domestic product, as well as controls for various forms of medical spending.
