RESUMO

Background: We investigate the relationship between the supply of methamphetamine and overdose death risk in Ohio. Ohio and the overall US have experienced a marked increase in overdose deaths from methamphetamine combined with fentanyl over the last decade. The increasing use of methamphetamine may be increasing the risk of overdose death. However, if people are using it to substitute away from more dangerous synthetic opioids, it may reduce the overall risk of overdose death. Methods: Ohio's Bureau of Criminal Investigation's crime lab data include a detailed list of the content of drug samples from law enforcement seizures, which are used as a proxy for drug supply. We use linear regressions to estimate the relationship between the proportion of methamphetamine in lab samples and unintentional drug overdose death rates from January 2015 through September 2021. Results: Relatively more methamphetamine in crime lab data in a county-month has either no statistically significant relationship with overdose death rates (in small and medium population counties) or a negative and statistically significant relationship with overdose death rates (in large population counties). Past overdose death rates do not predict future increases in methamphetamine in crime lab data. Conclusions: The results are consistent with a relatively higher supply of methamphetamine reducing the general risk of overdose death, possibly due to substitution away from more dangerous synthetic opioids. However, the supply of methamphetamine appears unrelated to the past illicit drug risk environment. The non-lethal and yet serious health effects of MA use were not explored and, thus, even if the presence of MA reduces the population-level overdose mortality rate, the rise of other adverse health effects may counteract any public health benefits of fewer deaths.

RESUMO

BACKGROUND: Illicitly manufactured fentanyls and stimulants are implicated in the escalating US mortality from drug overdose. San Francisco, California (SF) has seen declining fentanyl injection while smoking has increased. Beliefs and behaviors surrounding this development are not well understood. METHODS: The study used rapid ethnography to explore fentanyl and methamphetamine use in SF. The team conducted semi-structured interviews (n = 34) with participants recruited from syringe service programs. Video-recorded smoking sequences (n = 12), photography and daily field notes supplemented interview data. RESULTS: Difficulty injecting and fear of overdose motivated transitions from injecting to smoking. Fentanyl was extremely cheap-$10/gram-with variability in quality. Foil was the most commonly used smoking material but glass bubbles, bongs and dabbing devices were also popular. No reliable visible methods for determining fentanyl quality existed, however, participants could gauge potency upon inhalation, and developed techniques to regulate dosage. Several participants reported at least hourly use, some reporting one or more grams of daily fentanyl consumption. Smoking was also very social, with people sharing equipment, drugs and information. Participants raised concerns about hygiene and overdose risk to others arising from shared equipment. Reportedly potent fentanyl 'residue' accumulated on smoking materials and was commonly shared/traded/stolen or consumed accidentally with diverse preferences for its use. CONCLUSION: Our data highlight fentanyl residue as a new overdose risk with potential mismatch between the potency of the residual drug and the recipient's tolerance. Further, large doses of fentanyl are being consumed (estimated at approximately 50 mg of pure fentanyl/day). Smoking fentanyl has potential health benefits over injecting and may be protective against overdose, but substantial uncertainty exists. However, SF overdose mortality hit a record high in 2023. Recommendations to reduce fentanyl smoking overdose risks through pacing, greater awareness of dosages consumed and checking tolerance of residue recipients are potentially viable interventions deserving further exploration.

RESUMO

This qualitative study explored the experiences of people living with HIV (PLWH) in the San Francisco Bay Area, United States, during the COVID-19 pandemic and subsequent public health restrictions at a safety net HIV clinic. Patients (N = 30) were recruited for Spanish/English language semi-structured interviews (n = 30), translated when necessary, and analyzed thematically. The recurring theme of "pandemic expertise" emerged from the data: skills and attitudes developed through living with HIV helped PLWH cope with the COVID-19 pandemic, including effective strategies for dealing with anxiety and depression; appreciation for life; and practical experience of changing behavior to protect their health. A subset did not consider living with HIV helped them adapt to the COVID-19 pandemic, with some describing their lives as chaotic due to housing issues and/or ongoing substance use. Overall, interviewees reported finding trustworthy health information that helped them follow COVID-19 prevention strategies. Although living with HIV is associated with a higher prevalence of mental health concerns, substance use, and stigma, these challenges can also contribute to increased self-efficacy, adaptation, and resilience. Addressing structural issues such as housing appears to be key to responding to both pandemics.

RESUMO

BACKGROUND: Opioid and methamphetamine co-use is increasing across the USA with overdoses involving these drugs also rising. West Virginia (WV) has led the US in opioid overdose death rates since at least 2013 and rising co-use of methamphetamine with opioids has played a greater role in deaths over the last 5 years. METHODS: This study used rapid ethnography to examine methods and motivations behind opioids and methamphetamine co-use from the viewpoint of their consumers. Participants (n = 30) were people who injected heroin/fentanyl also using methamphetamine who participated in semi-structured interviews. RESULTS: We found multiple methods of co-using opioids and methamphetamine, whether alternately or simultaneously and in varying order. Most prioritized opioids, with motives for using methamphetamine forming three thematic categories: 'intrinsic use', encompassing both inherent pleasure of combined use greater than using both drugs separately or for self-medication of particular conditions; 'opioid assisting use' in which methamphetamine helped people manage their existing heroin/fentanyl use; and 'reluctant or indifferent use' for social participation, reflecting methamphetamine's low cost and easy availability. CONCLUSIONS: Methamphetamine serves multiple functions among people using opioids in WV. Beliefs persist that methamphetamine can play a role in preventing and reversing opioid overdose, including some arguments for sequential use being protective of overdose. 'Reluctant' uptake attests to methamphetamine's social use and the influence of supply. The impact on overdose risk of the many varied co-use patterns needs further investigation.

RESUMO

In the United States, HIV outbreaks are occurring in areas most affected by the opioid epidemic, including West Virginia (WV). Cultural Theory contends that multiple cultures co-exist within societies distinguished by their differing intensities of rules or norms of behavior ('grid') or degree of group allegiance/individual autonomy ('group'). Accordingly, we would expect that perceptions about HIV, including stigma, correspond with individuals' grid/group attributes. To explore this, we conducted qualitative interviews with people who inject drugs (PWID) recruited from a WV syringe service program. This paper focuses on our unexpected findings on stigma during a coinciding HIV outbreak. PWID living homeless identified as belonging to a 'street family'. Its members were mutually distrustful and constrained by poverty and drug dependence but despite their conflicts, reported openness between each other about HIV + status. Interviewees living with HIV perceived little enacted stigma from peers since the local outbreak. Contrasting stigmatizing attitudes were attributed to the town's mainstream society. The 'High Five' (Hi-V) Club, expressing defiance towards stigmatizing behavior outside the street family, epitomized the tensions between a desire for solidary and mutual support and a fatalistic tendency towards division and distrust. Fatalism may hinder cooperation, solidarity and HIV prevention but may explain perceived reductions in stigma.

RESUMO

BACKGROUND: West Virginia is a largely rural state with strong ties of kinship, mutual systems of support and charitable giving. At the same time, wealth inequalities are extreme and the state's drug overdose fatality rate stands above all others in the USA at 51.5/100,000 in 2018, largely opioid-related. In recent years, harm reduction services have been active in the state but in 2018 Charleston's needle and syringe program was forced to close. This paper considers the risk environment in which the state's drug-related loss of life, and those attempting to prevent it, exist. METHODS: This rapid ethnographic study involved semi-structured interviews (n = 21), observation and video recordings of injection sequences (n = 5), initially recruiting people who inject heroin/fentanyl (PWIH) at the Charleston needle and syringe program. Snowball sampling led the research team to surrounding towns in southern West Virginia. Telephone interviews (n = 2) with individuals involved in service provision were also carried out. RESULTS: PWIH in southern West Virginia described an often unsupportive, at times hostile risk environment that may increase the risk of overdose fatalities. Negative experiences, including from some emergency responders, and fears of punitive legal consequences from calling these services may deter PWIH from seeking essential help. Compassion fatigue and burnout may play a part in this, along with resentment regarding high demands placed by the overdose crisis on impoverished state resources. We also found low levels of knowledge about safe injection practices among PWIH. CONCLUSIONS: Hostility faced by PWIH may increase their risk of overdose fatalities, injection-related injury and the risk of HIV and hepatitis C transmission by deterring help-seeking and limiting the range of harm reduction services provided locally. Greater provision of overdose prevention education and naloxone for peer distribution could help PWIH to reverse overdoses while alleviating the burden on emergency services. Although essential for reducing mortality, measures that address drug use alone are not enough to safeguard longer-term public health. The new wave of psychostimulant-related deaths underline the urgency of addressing the deeper causes that feed high-risk patterns of drug use beyond drugs and drug use.

RESUMO

BACKGROUND: Illicitly manufactured fentanyl and its analogues are appearing in countries throughout the world, often disguised as heroin or counterfeit prescription pills, with resulting high overdose mortality. Possible explanations for this phenomenon include reduced costs and risks to heroin suppliers, heroin shortages, user preferences for a strong, fast-acting opioid and the emergence of Dark Web cryptomarkets. This paper addresses these potential causes and asks three questions: (1) can users identify fentanyl; (2) do users desire fentanyl; and (3) if users want fentanyl, can they express this demand in a way that influences the supply? ARGUMENT/ANALYSIS: Existing evidence, while limited, suggests that some users can identify fentanyl, although not reliably, and some desire it, but because fentanyl is frequently marketed deceptively as other drugs, users lack information and choice to express demand effectively. Even when aware of fentanyl's presence, drug users may lack fentanyl-free alternatives. Cryptomarkets, while difficult to quantify, appear to offer buyers greater information and competition than offline markets. However, access barriers and patterns of fentanyl-related health consequences make cryptomarkets unlikely sources of user influence on the fentanyl supply. Market condition data indicate heroin supply shocks and shortages prior to the introduction of fentanyl in the United States and parts of Europe, but the much lower production cost of fentanyl compared with heroin may be a more significant factor CONCLUSION: Current evidence points to a supply-led addition of fentanyl to the drug market in response to heroin supply shocks and shortages, changing prescription opioid availability and/or reduced costs and risks to suppliers. Current drug users in affected regions of the United States, Canada and Europe appear largely to lack both concrete knowledge of fentanyl's presence in the drugs they buy and access to fentanyl-free alternatives.

RESUMO

BACKGROUND: Internationally, overdose is the primary cause of death among people injecting drugs. However, since 2001, heroin-related overdose deaths in the United States (US) have risen sixfold, paralleled by a rise in the death rate attributed to synthetic opioids, particularly the fentanyls. This paper considers the adaptations some US heroin injectors are making to protect themselves from these risks. METHODS: Between 2015 and 2016, a team of ethnographers collected data through semi-structured interviews and observation captured in field notes and video recording of heroin preparation/consumption. Ninety-one current heroin injectors were interviewed (Baltimore, n = 22; Chicago, n = 24; Massachusetts and New Hampshire, n = 36; San Francisco, n = 9). Experience injecting heroin ranged from < 1-47 years. Eight participants, who were exclusively heroin snorters, were also interviewed. Data were analyzed thematically. RESULTS: Across the study sites, multiple methods of sampling "heroin" were identified, sometimes used in combination, ranging from non-injecting routes (snorting, smoking or tasting a small amount prior to injection) to injecting a partial dose and waiting. Partial injection took different forms: a "slow shot" where the user injected a portion of the solution in the syringe, keeping the needle in the injection site, and continuing or withdrawing the syringe or a "tester shot" where the solution was divided into separate injections. Other techniques included getting feedback from others using heroin of the same batch or observing those with higher tolerance injecting heroin from the same batch before judging how much to inject themselves. Although a minority of those interviewed described using these drug sampling techniques, there is clearly receptivity among some users to protecting themselves by using a variety of methods. CONCLUSIONS: The use of drug sampling as a means of preventing an overdose from injection drug use reduces the quantity absorbed at any one time allowing users to monitor drug strength and titrate their dose accordingly. Given the highly unpredictable potency of the drugs currently being sold as heroin in the US, universal precautions should be adopted more widely. Further research is needed into facilitators and barriers to the uptake of these drug sampling methods.

RESUMO

Since 2001, heroin-related overdose deaths in the United States have risen six-fold, a rise unaccounted for by the expanding user population. Has heroin become a more dangerous drug? Reports of fentanyl and its analogs, often concealed in or sold as heroin, have also increased sharply. This article investigates heroin injectors' perceptions and experiences of changes in the heroin supply in the East Coast city of Baltimore, Maryland, currently facing an epidemic in heroin- and fentanyl-related overdose deaths. Unusually, Baltimore's heroin market is divided between two types: "Raw," believed to be Colombian in origin and relatively pure, and the more adulterated "Scramble" (raw heroin traditionally blended with quinine and lactose). Users reported that Scramble heroin, while gaining market share, has become a highly unstable product, varying dramatically in appearance, intensity of onset, duration of action, and effect. Some considered that Scramble was no longer "heroin," but was heavily adulterated or even replaced, mentioning fentanyl, benzodiazepines, and crushed opioid pills as additives. There was intense awareness of overdose as a present danger in users' lives, which they linked to the recent adulteration of the heroin supply. Responses to this perceived adulteration varied, including information gathering, attraction, avoidance, taking precautions, and acceptance.

RESUMO

BACKGROUND: The US is experiencing an unprecedented opioid overdose epidemic fostered in recent years by regional contamination of the heroin supply with the fentanyl family of synthetic opioids. Since 2011 opioid-related overdose deaths in the East Coast state of Massachusetts have more than tripled, with 75% of the 1374 deaths with an available toxicology positive for fentanyl. Fentanyl is 30-50X more potent than heroin and its presence makes heroin use more unpredictable. A rapid ethnographic assessment was undertaken to understand the perceptions and experiences of people who inject drugs sold as 'heroin' and to observe the drugs and their use. METHODS: A team of ethnographers conducted research in northeast Massachusetts and Nashua, New Hampshire in June 2016, performing (n=38) qualitative interviews with persons who use heroin. RESULTS: (1) The composition and appearance of heroin changed in the last four years; (2) heroin is cheaper and more widely available than before; and (3) heroin 'types' have proliferated with several products being sold as 'heroin'. These consisted of two types of heroin (alone), fentanyl (alone), and heroin-fentanyl combinations. In the absence of available toxicological information on retail-level heroin, our research noted a hierarchy of fentanyl discernment methods, with embodied effects considered most reliable in determining fentanyl's presence, followed by taste, solution appearance and powder color. This paper presents a new 'heroin' typology based on users' reports. CONCLUSION: Massachusetts' heroin has new appearances and is widely adulterated by fentanyl. Persons who use heroin are trying to discern the substances sold as heroin and their preferences for each form vary. The heroin typology presented is inexact but can be validated by correlating users' discernment with drug toxicological testing. If validated, this typology would be a valuable harm reduction tool. Further research on adaptations to heroin adulteration could reduce risks of using heroin and synthetic opioid combinations.

RESUMO

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.

RESUMO

INTRODUCTION: Little is known about trends in national rates of injection-related skin and soft tissue infections (SSTI) and their relationship to the structural risk environment for heroin users. Use of Mexican-sourced "Black Tar" heroin, predominant in western US states, may have greater risk for SSTI compared with eastern US powder heroin (Colombian-sourced) due to its association with non-intravenous injection or from possible contamination. METHODS: Using nationally representative hospital admissions data from the Nationwide Inpatient Sample and heroin price and purity data from the Drug Enforcement Administration, we looked at rates of hospital admissions for opiate-related SSTI (O-SSTI) between 1993 and 2010. Regression analyses examined associations between O-SSTI and heroin source, form and price. RESULTS: Hospitalization rates of O-SSTI doubled from 4 to 9 per 100,000 nationally between 1993 and 2010; the increase concentrated among individuals aged 20-40. Heroin market features were strongly associated with changes in the rate of SSTI. Each $100 increase in yearly heroin price-per-gram-pure was associated with a 3% decrease in the rate of heroin-related SSTI admissions. Mexican-sourced-heroin-dominant cities had twice the rate of O-SSTI compared to Colombian-sourced-heroin-dominant cities. DISCUSSION: Heroin-related SSTI are increasing and structural factors, including heroin price and source-form, are associated with higher rates of SSTI hospital admissions. Clinical and harm reduction efforts should educate heroin users on local risk factors, e.g., heroin type, promote vein health strategies and provide culturally sensitive treatment services for persons suffering with SSTI.

RESUMO

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.

RESUMO

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.

RESUMO

Over the last 50 years, tobacco has been excluded from and then included in the category of addictive substances. We investigated influences on these opposing definitions and their application in expert witness testimony in litigation in the 1990s and 2000s. A scientist with ties to the tobacco industry influenced the selection of a definition of addiction that led to the classification of tobacco as a "habituation" in the 1964 Surgeon General's Advisory Committee report. Tobacco was later defined as addictive in the 1988 surgeon general's report. Expert witnesses for tobacco companies used the 1964 report's definition until Philip Morris Tobacco Company publicly changed its position in 1997 to agree that nicotine was addictive. Expert witnesses for plaintiffs suing the tobacco industry used the 1988 report's definition, arguing that new definitions were superior because of scientific advance.
