Capturing illicit drug use where and when it happens: an ecological momentary assessment of the social, physical and activity environment of using versus craving illicit drugs.

To understand the environmental and contextual influences of illicit cocaine and heroin use and craving using mobile health (mHealth) methods. Interactive mHealth methods of ecological momentary assessment (EMA) were utilized in the Exposure Assessment in Current Time (EXACT) study to assess drug use and craving among urban drug users in real time. Participants were provided with mobile devices and asked to self-report every time they either craved (without using) or used heroin or cocaine for 30 days from November 2008 through May 2013. Baltimore, MD, USA. A total of 109 participants from the AIDS Linked to the IntraVenous Experience (ALIVE) study. For each drug use or craving event, participants answered questions concerning their drug use, current mood and their social, physical and activity environments. Odds ratios (OR) of drug use versus craving were obtained from logistic regression models with generalized estimating equations of all reported events. Participants were a median of 48.5 years old, 90% African American, 52% male and 59% HIV-infected. Participants were significantly more likely to report use rather than craving drugs if they were with someone who was using drugs [adjusted odds ratio (aOR) = 1.45, 95% confidence interval (CI) = 1.13, 1.86), in an abandoned space (aOR = 6.65, 95% CI = 1.78, 24.84) or walking/wandering (aOR = 1.68, 95% CI = 1.11, 2.54). Craving drugs was associated with being with a child (aOR = 0.26, 95% CI = 0.12, 0.59), eating (aOR = 0.54, 95% CI = 0.34, 0.85) or being at the doctor's office (aOR = 0.31, 95% CI = 0.12, 0.80). There are distinct drug using and craving environments among urban drug users, which may provide a framework for developing real-time context-sensitive interventions.

Urban vs. rural differences in prescription opioid misuse among adults in the United States: Informing region specific drug policies and interventions

BackgroundIn the United States, prescription opioid misuse (POM) has increased dramatically over the past two decades. However, there are still questions regarding whether rural/urban differences in adult POM exist, and more important, which factors might be driving these differences. MethodsUsing data from the 2011 and 2012 National Survey on Drug Use and Health, we conducted unadjusted and adjusted binary logistic regression analyses to determine the association between metropolitan status and POM. ResultsWe found that urban adults were more likely to engage in POM compared to rural adults because of their higher use of other substances, including alcohol, cannabis, and other illicit and prescription drugs, and because of their greater use of these substances as children. ConclusionThis study fills an important gap in the literature by not only identifying urban/rural differences in POM, but by also pointing out factors that mediate those differences. Because patterns and predictors of POM can be unique to geographic region, this research is critical to informing tailored interventions and drug policy decisions. Specifically, these findings suggest that interventions should be aimed at urban illicit drug users and adults in manual labor occupations.

Patterns, determinants and barriers of health and social service utilization among young urban crack users in Brazil

BackgroundCrack use is prevalent across the Americas, and specifically among marginalized urban street drug users in Brazil. Crack users commonly feature multiple physical and mental health problems, while low rates of and distinct barriers to help service use have been observed in these populations. This study examined profiles and determinants of social and health service utilization, and unmet service needs, in a two-city sample of young (18–24 years), marginalized crack users in Brazil.MethodsN = 160 study participants were recruited by community-based methods from impoverished neighborhoods in the cities of Rio de Janeiro (n = 81) and Salvador (n = 79). A mixed methods protocol was used. Participants’ drug use, health, and social and health service utilization characteristics were assessed by an anonymous interviewer-administered questionnaire completed in a community setting; descriptive statistics on variables of interest were computed. Service needs and barriers were further assessed by way of several focus groups with the study population; narrative data were qualitatively analyzed. The study protocol was approved by institutional ethics review boards; data were collected between November 2010 and June 2011.ResultsThe majority of the sample was male, without stable housing, and used other drugs (e.g., alcohol, marijuana). About half the sample reported physical and mental health problems, yet most had not received medical attention for these problems. Only small minorities had utilized locally available social or health services; utilization appeared to be influenced by sex, race and housing characteristics in both sites. Participants cited limited service resources, lack of needs-specific professional skills, bureaucratic barriers and stigma as obstacles to better service access. However, most respondents stated strong interest and need for general social, health and treatment services designed for the study population, for which various key features were emphasized as important.ConclusionsThe study contributes substantive evidence to current discussions about the development and utilization of health and treatment interventions for crack use in Brazil. Based on our data, crack users’ social, service needs are largely unmet; these gaps appear to partly root in systemic barriers of access to existing services, while improved targeted service offers for the target population seem to be needed also.

The prevalence and correlates of single cigarette selling among urban disadvantaged drug users in Baltimore, Maryland

BackgroundSelling of single cigarettes, also known as loosies, is a public health concern. Loosies allow for those with fewer resources to buy cigarettes without having to purchase a pack. Selling of loosies may cue smoking behaviors. In the US, socioeconomically disadvantaged populations have high rates of smoking and illicit drug use and the selling of loosies appears to be linked to the urban informal economy. We examined the proportion and frequency of cigarette selling and roles in the informal economy associated with selling loosies among a sample of urban drug users. MethodsThere were 801 participants, recruited by community outreach, assessed at baseline, who were enrolled in an HIV prevention intervention for drug users. ResultsMost (89%) smoked cigarettes in the prior 30 days, of whom 92% smoked daily. Self-reported selling of cigarettes was common with 58% reporting that they had sold cigarettes within the last six months; 20.4% reported selling cigarettes a few times a week and 7.4% reported daily selling of cigarettes. In a stepwise regression model, four sources of income were associated with frequent cigarette selling: providing street security (OR=2.214, 95% CI 1.177–4.164), selling food stamps (OR=1.461, 95% CI 1.003–2.126), pawning items (OR=2.15, 95% CI 1.475–3.135), and selling drugs (OR=1.634, 95% CI 1.008–2.648). ConclusionThere is a high rate of selling loosies among urban substance users. The wide availability of loosies may promote smoking. Smoking cessation programs with drug treatment and economic development programs may help to reduce economic pressures to sell loosies.

Boredom, Depressive Symptoms, and HIV Risk Behaviors Among Urban Injection Drug Users

Boredom is closely aligned with depression, but is understood to be conceptually distinct. Little is known about boredom among active drug users and the potential association with depression and HIV risk. Current IDUs (n = 845) completed a baseline behavioral survey including socio-demographic characteristics, self-reported boredom, depressive symptoms (CESD score), and HIV risk behaviors. One-third of the sample reported high boredom in the past week. In multivariate analysis, those who reported boredom were less likely to be older, African-American, have a main partner, and to be employed at least part-time. Controlling for covariates, those with high boredom were almost five times as likely to report high depressive symptoms. Co-occurrence of boredom and depressive symptoms (28 %) was strongly and independently associated with a range of injection risk behaviors and sex exchange. This study demonstrates the need for more thorough understanding of mental health and HIV risk among urban drug users.

A Comparison of Rural and Urban Nonmedical Prescription Opioid Users’ Lifetime and Recent Drug Use

Background: Nonmedical prescription opioid use has emerged as a major public health concern. The growing burden of nonmedical prescription opioid use in America may have unique manifestations and consequences in rural areas, which to a large extent have yet to be explored. Objectives: To describe rural–urban differences among drug users in recent and lifetime use and age of onset of use for alcohol, heroin, OxyContin®, oxycodone, hydrocodone, barbiturates, benzodiazepines, cocaine, crack, methamphetamine, amphetamine, marijuana, hallucinogens, and inhalants. Methods: A purposive sample of 212 prescription drug users was recruited from a rural Appalachian county (n = 101) and a major metropolitan area (n = 111) in Kentucky. Consenting participants were given an interviewer-administered questionnaire examining sociodemographics, psychiatric characteristics, and self-reported drug use. Results: Rural drug users had significantly earlier ages of onset for use of oxycodone, hydrocodone, benzodiazepines, cocaine, and crack. In age-, gender-, and race-adjusted logistic regression analyses, rural drug users had significantly higher odds of lifetime and recent use of methadone, OxyContin®, and oxycodone. Rural drug users also had significantly higher odds of lifetime cocaine and crack use. However, urban participants as expected had significantly higher odds of recent crack use. Conclusions: The findings demonstrate that, in this sample, nonmedical prescription opioid use is dissimilar among rural and urban drug users. Additional research is needed to better understand the individual, social, and structural level factors contributing to the burden of nonmedical opioid use, particularly in rural populations, with the aim of developing tailored substance abuse treatment and prevention.

Prevalence of Human Immunodeficiency Virus (HIV), Risk Behavior, and Recent Substance Use in a Sample of Urban Drug Users: Findings by Race and Sex

The aim of the current study was to examine the prevalence of HIV, past six-month illicit drug use, and risk behaviors among a population of heavy drug users living in an urban setting. Although many studies investigate substance use, sex-risk behavior, and HIV by race and gender, no studies have examined these variables simultaneously. The current study seeks to fill this gap in the literature by exploring HIV prevalence among a predominantly heterosexual sample of recent substance users by injection drug use (IDU) status, race, and sex. Baseline data from the Baltimore site of the NEURO-HIV epidemiologic study was used in this study. This study examines neuropsychological and social-behavioral risk factors of HIV, hepatitis A, hepatitis B, and hepatitis C among both injection and non-injection drug users. Descriptive statistics and chi-square statistics were used in data analyses. Blood and urine samples were obtained to test for the presence of recent drug use, viral hepatitis, HIV, and other sexually transmitted diseases (STDs). Findings presented here have several important implications for HIV prevention and care among substance users. Intervention programs that incorporate substance use treatment in addition to HIV education, particularly with respect to substance use and sex risk behavior are imperative.

Neighborhood Disorder and Incarceration History Among Urban Substance Users

This research examines the relationship between neighborhood physical and social disorder and incarceration history among urban drug users. A cohort of 358 African American and White urban drug users completed a clinical interview and psychological assessment that emphasized cognitive and social-behavioral HIV risk factors. The Neighborhood Inventory for Environmental Typology was used to assess indicators of physical and social disorder. After controlling for age, gender, education, and having a place to live, multivariable analyses revealed that living in a neighborhood with moderate or high levels of disorder (odds ratio [OR] = 1.63; 95% confidence interval [CI] = [1.02, 2.59]) and drinking alcohol every day or nearly every day for 3 months or more (OR = 2.03; 95% CI [1.24, 3.31]) were associated with incarceration history. Findings suggest that select characteristics of disadvantaged communities may be important determinants of incarceration vulnerability among urban substance users. Residential improvements hold promise to enhance interventions aimed to reduce incarceration.

Prevalence and risk factors for unrecognized obstructive lung disease among urban drug users

BackgroundObstructive lung disease (OLD) is frequently unrecognized and undertreated. Urban drug users are at higher risk for OLD due to race, behavioral, and socioeconomic characteristics, yet little data exist on prevalence and risk factors associated with unrecognized OLD in this population.ObjectiveThe objective of this study is to determine the prevalence of unrecognized OLD in an urban population and identify the characteristics associated with lack of physician-diagnosed OLD.DesignCross-sectional analysis from the Acquired Immunodeficiency Syndrome Linked to the Intravenous Experience (ALIVE) study, an observational study of current and former injection drug users in Baltimore, Maryland, USA.ParticipantsAll participants with spirometry-defined airflow obstruction were stratified by the presence or absence of physician diagnosis of OLD.Main measuresUsing cross-sectional demographic, clinical, and spirometric measurements, multivariable regression models were generated to identify factors independently associated with unrecognized OLD.Key resultsOf the 1083 participants evaluated in the ALIVE lung substudy, 176 (16.3%) met spirometric criteria for OLD. Of those, only 88 (50%) had a physician diagnosis of OLD. The prevalence of unrecognized OLD decreased as severity of airflow obstruction increased. Factors independently associated with unrecognized OLD were absence of respiratory symptoms (prevalence ratio [PR], 1.70; 95% confidence interval [CI]: 1.29–2.23; P < 0.01) and less severe dyspnea (PR, 0.83; 95% CI: 0.72–0.96, per point increase in dyspnea scale; P = 0.01). In the subset of human immunodeficiency virus (HIV)–infected participants, the use of antiretroviral therapy (ART) was independently associated with an increased prevalence of unrecognized OLD (PR, 1.93; 95% CI: 1.05–3.56; P = 0.03).ConclusionsIn a cohort of current and former urban drug users, OLD is substantially underrecognized and associated with lack of respiratory symptoms. Relying on the presence of respiratory symptoms as a trigger to perform spirometry may result in a substantial underdiagnosis of OLD in this population. HIV-infected individuals receiving ART are a population particularly vulnerable to unrecognized OLD.

How Alcoholics Anonymous (AA) and Narcotics Anonymous (NA) Work: Cross-Disciplinary Perspectives

Evidence from multiple lines of research supports the effectiveness and practical importance of Alcoholics Anonymous and Narcotics Anonymous. Conference presenters discussed the relationship between 12-Step participation and abstinence among various populations, including adolescents, women, and urban drug users. Insight from the arts and humanities placed empirical findings in a holistic context.

Psychiatric context of Human Immunodeficiency Virus infection among former plasma donors in rural China

BackgroundChina's HIV epidemic commenced in its agrarian provinces through contaminated commercial plasma donation centers and is now becoming a public health concern nationwide. Little is known of the psychiatric and substance use disorder characteristics of this population, or their impact on everyday function, employment, and life quality. MethodsHIV-infected (HIV+) former plasma donors (N=203) and HIV-negative (HIV−) donor controls (N=198) completed the World Mental Health Survey Composite International Diagnostic Interview to determine lifetime major depressive disorder (MDD), substance use disorders, and suicidality. Current mood and suicidality were assessed with the Beck Depression Inventory-II. Everyday function was measured by an Activity of Daily Living questionnaire; life quality was evaluated by the Medical Outcomes Study — HIV. ResultsHIV+ participants had known their infected status for 2years on average. Most were taking antiretroviral treatment and had frank AIDS. Rates of current MDD were similar across groups (1–2%), but HIV+ had a higher frequency of lifetime MDD (14% vs. 5%, p<.05). Its onset preceded date of known infection in one-third of cases. Alcoholism was the only substance use disorder detected; HIV+ had a higher proportion of lifetime substance use diagnoses (14% vs. 6%, p<.05). Depression and AIDS independently predicted worse daily functioning and life quality, and unemployment. LimitationsThe epicenter of China HIV has moved into urban injection drug users, limiting the representativeness of this sample. ConclusionsHigh rates of MDD and its impact suggest that in China, as elsewhere, comprehensive care requires detection and treatment of mood disorder.

Route of administration for illicit prescription opioids: a comparison of rural and urban drug users

BackgroundNonmedical prescription opioid use has emerged as a major public health concern in recent years, particularly in rural Appalachia. Little is known about the routes of administration (ROA) involved in nonmedical prescription opioid use among rural and urban drug users. The purpose of this study was to describe rural-urban differences in ROA for nonmedical prescription opioid use.MethodsA purposive sample of 212 prescription drug users was recruited from a rural Appalachian county (n = 101) and a major metropolitan area (n = 111) in Kentucky. Consenting participants were given an interviewer-administered questionnaire examining sociodemographics, psychiatric disorders, and self-reported nonmedical use and ROA (swallowing, snorting, injecting) for the following prescription drugs: buprenorphine, fentanyl, hydrocodone, hydromorphone, methadone, morphine, OxyContin® and other oxycodone.ResultsAmong urban participants, swallowing was the most common ROA, contrasting sharply with substance-specific variation in ROA among rural participants. Among rural participants, snorting was the most frequent ROA for hydrocodone, methadone, OxyContin®, and oxycodone, while injection was most common for hydromorphone and morphine. In age-, gender-, and race-adjusted analyses, rural participants had significantly higher odds of snorting hydrocodone, OxyContin®, and oxycodone than urban participants. Urban participants had significantly higher odds of swallowing hydrocodone and oxycodone than did rural participants. Notably, among rural participants, 67% of hydromorphone users and 63% of morphine users had injected the drugs.ConclusionsAlternative ROA are common among rural drug users. This finding has implications for rural substance abuse treatment and harm reduction, in which interventions should incorporate methods to prevent and reduce route-specific health complications of drug use.

Motivations for Sexual Risk Behavior Across Commercial and Casual Partners Among Male Urban Drug Users: Contextual Features and Clinical Correlates

The current study aimed to develop a measure for assessing the various motivations for sexual risk behavior (SRB) across commercial (involving the exchange of sex for money or drugs) and casual (nonregular) partners in a sample of inner-city, primarily African American drug users, and to examine the relationship of these motivations with a history of childhood trauma, as well as current symptoms of depression, posttraumatic stress disorder (PTSD), and borderline personality disorder (BPD). Exploratory factor analysis indicated a 5-factor solution for commercial partner type, and a 4-factor solution for casual partner type, including the motivations of sexual sensation-seeking, intimacy seeking, reassurance-seeking, emotional avoidance, and emotional expressivity. Emotional avoidance and emotional expressivity were strongly related to childhood trauma and PTSD and BPD symptoms. These results provide initial results for mechanisms underlying the relationship between SRB and a history of trauma and psychopathology.

Barriers and Opportunities for Recruitment for Nonintervention Studies on HIV Risk: Perspectives of Street Drug Users

This study used focus-group discussions in response to a video vignette to examine attitudes toward recruitment for nonintervention research involving HIV testing. Participants were 100 ethnically diverse, economically disadvantaged urban drug users, who were recruited from New York City and Hartford, Connecticut in the spring and summer of 2006. Content analyses revealed themes including (1) fears of stigma and legal trouble balanced by trustworthiness of the recruiter; (2) fears of learning one's HIV status balanced by prospects for health benefits, and (3) the right to receive fair monetary compensation balanced by risks of coercion during periods of cravings. Limitations and implications for recruitment practices have been discussed here.

Association between neighbourhood socioeconomic characteristics and high-risk injection behaviour amongst injection drug users living in inner and other city areas in Montréal, Canada

Background Area-level socioeconomic conditions are associated with epidemic rates of viral hepatitis and HIV amongst urban injection drug users (IDUs), but whether specific socioeconomic markers are uniformly related to IDU outcomes across different urban environments is unclear. We evaluated whether injection behaviour is differentially related to neighbourhood socioeconomic characteristics for IDUs in inner city vs. surrounding urban areas. Methods The study population was 468 active IDUs on the Island of Montréal. Neighbourhoods were represented as 500 m radius buffers around individual IDU dwelling places. High-risk injection behaviour (HRIB) was defined dichotomously. Relations between neighbourhood socioeconomic disadvantage (percentage households below low-income cutoff), neighbourhood educational attainment (percentage adults with university degree), and HRIB were assessed using multivariate logistic regression. Stratified analyses were conducted for inner city IDUs ( n = 219), and those in surrounding areas ( n = 249). Results Similar proportions of IDUs in inner city and surrounding areas reported HRIB. Neighbourhood socioeconomic characteristics were not associated with HRIB for IDUs in surrounding areas. For inner city IDUs, those in socioeconomically disadvantaged neighbourhoods were more likely to practice HRIB (OR 4.34; 95% CI 1.15–16.35). Conversely, inner city IDUs residing in lower educational attainment neighbourhoods had a lower odds of HRIB (OR 0.41; 95% CI 0.21–0.80). Conclusion HRIB did not vary according to urban environment but for inner-city IDUs was differentially related to socioeconomic markers. Associations between HRIB and neighbourhood socioeconomic disadvantage and lower educational attainment, positive and negative, respectively, indicate that adverse socioeconomic circumstances are not related to a uniformly greater likelihood of HRIB.

Structural and Personal Factors Related to Access to Housing and Housing Stability among Urban Drug Users in Hartford, Connecticut

Several policies criminalizing drug use significantly impact drug users' access to housing. This article explores the impact of housing policies on active drug users' access to housing and structural and personal factors related to their homelessness and housing stability. Qualitative interviews were conducted with 65 active cocaine or heroin users at baseline, three and six months. Participants were purposively sampled to reflect a variety of housed and homeless statuses. Interviews were analyzed to explore the processes associated with changes in housing status. Factors that led to homelessness included arrest, eviction, absence of housing subsidies, and lack of social support. Participants reported being evicted, and losing housing subsidies, welfare entitlements, and important social relationships following arrest. Criminal histories also limited their ability to find employment and permanent housing. Factors that led to housing stability included having family support, housing subsidies, and social supportive services. Active drug users can maintain independent housing when provided appropriate structural supports including rental subsidies and social services. But arrest disrupts drug users' housing stability. Programs to appropriately house those released from jail could help decrease homelessness among this population.

Prevalence of opioid analgesic injection among rural nonmedical opioid analgesic users

Objective The purpose of this study was to examine the prevalence and correlates of opioid analgesic injection (OAI) in a cohort of rural opioid analgesic users. Methods Cross-sectional study of 184 participants from rural Appalachian Kentucky. Results The majority of participants were male (54.9%), white (98.4%) and the median age was 30 years (interquartile range: 24–37). The self-reported lifetime prevalence of injection drug use (IDU) was 44.3%, with 35.3% of respondents reporting injection of oral opioid analgesic formulations. The prevalence of self-reported hepatitis C (HCV) was 14.8%, significantly greater than those not injecting opioid analgesics (1.7%) ( p < 0.001). Receptive needle sharing, distributive needle sharing and sharing of other injection paraphernalia was reported by 10.5%, 26.3%, and 42.1% of those currently injecting, respectively. Conclusions Opioid analgesic injection was more prevalent in this rural population than has been found in previous reports. This study suggests a rising problem with injecting among rural opioid users, a problem more typically associated with urban drug users. Educating injectors of opioid analgesics on safe needle practices is necessary in order to curb the transmission of HIV, HCV, and other infectious diseases. Further study on the longitudinal course of opioid analgesic injection in this population appears warranted.

Injection drug use and HIV/AIDS in China: review of current situation, prevention and policy implications.

Illicit drug abuse and HIV/AIDS have increased rapidly in the past 10 to 20 years in China. This paper reviews drug abuse in China, the HIV/AIDS epidemic and its association with injection drug use (IDU), and Chinese policies on illicit drug abuse and prevention of HIV/AIDS based on published literature and unpublished official data. As a major drug trans-shipment country with source drugs from the "Golden Triangle" and "Gold Crescent" areas in Asia, China has also become an increasingly important drug consuming market. About half of China's 1.14 million documented drug users inject, and many share needles. IDU has contributed to 42% of cumulatively reported HIV/AIDS cases thus far. Drug trafficking is illegal in China and can lead to the death penalty. The public security departments adopt "zero tolerance" approach to drug use, which conflict with harm reduction policies of the public health departments. Past experience in China suggests that cracking down on drug smuggling and prohibiting drug use alone can not prevent or solve all illicit drug related problems in the era of globalization. In recent years, the central government has outlined a series of pragmatic policies to encourage harm reduction programs; meanwhile, some local governments have not fully mobilized to deal with drug abuse and HIV/AIDS problems seriously. Strengthening government leadership at both central and local levels; scaling up methadone substitution and needle exchange programs; making HIV voluntary counseling and testing available and affordable to both urban and rural drug users; and increasing utilization of outreach and nongovernmental organizations are offered as additional strategies to help cope with China's HIV and drug abuse problem.

Ecstasy use and its Association with Sexual Behaviors Among Drug Users in New York City

In the past two decades, recreational use of ecstasy has become a growing concern in the United States, although most studies assessing ecstasy use have focused on white, middle-class adolescents who use ecstasy during raves and in clubs. We assessed the prevalence of recent ecstasy use among predominantly minority heroin, cocaine, and crack users in New York City and the association between ecstasy and sexual risk above and beyond that of the other drugs. Between 2002 and 2004, injection and non-injection heroin, crack and cocaine users (N= 534) completed a risk behavior questionnaire that included items on ecstasy use. Logistic regression was used to investigate the relation between current ecstasy use and sexual behaviors. Of 534 illicit drug users, 69.7% were aged 25 years or older, 65.2% were Hispanic, 27.9% Black and 77.4% male; 36.7% were injectors. 17.2% of respondents reported recent (last six months) ecstasy use. In a multivariable logistic regression model, current ecstasy use was associated both with initiating sex before age 14 (adjusted odds ratio (AOR) = 1.51) and having two or more partners in the past two months (AOR = 1.86) after adjusting for age at study entry, current cocaine and marijuana use and being an injection drug user. This study suggests that ecstasy use may be more prevalent among urban drug users. Ecstasy use in urban settings, beyond clubs and raves, should continue to be monitored.
