Multiple Determinants of Specific Modes of Prescription Opioid Diversion.

Numerous national surveys and surveillance programs have shown a substantial rise in the abuse of prescription opioids over the past 15 years. Accessibility of these drugs to non-patients is the result of their unlawful channeling from legal sources to the illicit marketplace (diversion). Empirical data on diversion remain absent from the literature. This paper examines abusers' sources of diverted drugs from two large studies: 1) a national sample of opioid treatment clients (N=1983), and 2) a South Florida study targeting diverse populations of opioid abusers (N=782). The most common sources of diverted medications were dealers, sharing/trading, legitimate medical practice (e.g., unknowing medical providers), illegitimate medical practice (e.g., pill mills), and theft, in that order. Sources varied by users' age, gender, ethnicity, risk-aversiveness, primary opioid of abuse, injection drug use, physical health, drug dependence, and either access to health insurance or relative financial wealth. Implications for prescription drug control policy are discussed.

Correlates of heterosexual anal intercourse among substance-using club-goers.

Anal sexual intercourse represents the highest transmission risk for infection with the human immunodeficiency virus (HIV), yet much of what we know about anal sex is based on men who have sex with men (MSM). Less is known about heterosexual adults who practice anal sex, especially those who may be at risk for HIV such as substance users. The present study examined the demographic, sexual behaviors, substance use, and psychosocial correlates of recent anal intercourse among a heterosexual young adult sample of nightclub goers who also use substances. Data were drawn from an on-going natural history study of participants (n = 597) in Miami's club scene who use club drugs, use prescription medications for non-medical reasons, and were regular attendees of nightclubs. Participants who reported anal sex (n = 118) were more likely to be male, of moderate income, Latino, trade sex, have unprotected sex, and report victimization. Event-based and qualitative studies are needed to better understand the context in which anal sex occurs. Interventions that target heterosexual populations should include discussion about the risks of anal sex.

Prescription Drug Abuse & Diversion: Role of the Pain Clinic.

The goal of this research is to better understand the role that South Florida pain management clinics may be playing in the abuse and diversion of prescription drugs. This study explores 1) the characteristics and practices of pain clinics that may be facilitating the drug-seeking endeavors of prescription drug abusers and 2) the drug-seeking behaviors of prescription drug abusers who use pain clinics as a primary source for drugs. Thirty in-depth interviews were conducted with prescription drug abusers in South Florida. Interviews were transcribed verbatim and codes were generated based on thematic analyses of the data. Using grounded theory strategies, the analysis revealed six main themes: "pill mills", on-site pharmacies, liberal prescribing habits, "sponsoring" drug diversion, pain doctor/pharmacy shopping, and faking symptoms/documentation. These findings should provide insights for law enforcement, regulatory agencies, and industry as they attempt to develop appropriate policy initiatives and recommendations for best practices.

Integrating nine prescription opioid analgesics and/or four signal detection systems to summarize statewide prescription drug abuse in the United States in 2007.

PURPOSE: Integrate statewide rankings of abuse across different drugs and/or signal detection systems to summarize prescription drug abuse in each state in 2007. METHODS: Four signal detection systems (Opioid Treatment Programs, Key Informants, Drug Diversion, and Poison Centers) that covered heterogeneous populations collected data on the abuse of nine opioids: hydrocodone, immediate-release oxycodone, tramadol, extended-release [ER] oxycodone, fentanyl, morphine, methadone, hydromorphone, and buprenorphine). We introduce here linearized maps which integrate nine drugs within each system; four systems for each drug; or all drugs and systems. RESULTS: When rankings were integrated across drugs, Rhode Island, New Hampshire, Maine, West Virginia, and Michigan were in the highest tertile of abuse in three systems. When rankings were integrated across signal detection systems, there was a geographic clustering of states with the highest rates for ER oxycodone (in Tennessee, Mississippi, Kentucky, Ohio, Indiana, Michigan, and in Massachusetts, New Hampshire, Maine, and Vermont) and methadone (Massachusetts, Rhode Island, New Hampshire, Maine, Vermont, Connecticut, and New Jersey). When rankings were integrated across both drugs and signal detection systems, states with 3-digit ZIP codes below 269 (i.e., from Massachusetts to West Virginia): Massachusetts, New Hampshire, Maine, Vermont, Washington DC, Virginia, and West Virginia were in the highest tertile and only Delaware was in the lowest tertile. CONCLUSIONS: We have presented methods to integrate data on prescription opioid abuse collected by signal detection systems covering different populations. Linearized maps are effective graphical summaries that depict differences in the level of prescription opioid abuse at the state level.

Prescription opioid abuse and diversion in an urban community: the results of an ultrarapid assessment.

OBJECTIVE: Prescription-drug diversion is a topic about which comparatively little is known, and systematic information garnered from prescription-drug abusers and dealers on the specific mechanisms of diversion is extremely limited. DESIGN: A pilot ultrarapid assessment was carried out in Wilmington, Delaware, during December 2006 to better understand the scope and dynamics of prescription-drug abuse and diversion. This involved focus groups with prescription-drug abusers and key informant interviews with police, regulatory officials, prescription-drug dealers, and pill brokers. SETTING AND PATIENTS: The research team recruited focus group participants from the two residential substance abuse treatment programs in Wilmington reporting the highest proportions of prescription drug abusing clients. A total of six focus groups were conducted with 32 patients in these two programs. Dealers were recruited from the same treatment facilities, and three in-depth interviews were completed. In-depth interviews were also conducted with two prescription pill brokers recruited through the authors' existing contacts in the drug abusing community. Six in-depth interviews were conducted with representatives from a number of Delaware agencies-the Attorney General's Office, the Department of Professional Regulation, the State Police; the Wilmington Police Department, and the Newark Police Department. MEASURES: In-depth interview and focus group guides were developed for each of the target populations. The in-depth interviews with police and regulatory officials focused on the extent of prescription drug abuse and diversion in the community, the types of drugs most commonly diverted, and mechanisms being used to channel the drugs to the illicit market. The focus group areas of inquiry with prescription drug abusers included general perceptions of the prescription drug problem in Delaware, sources and mechanisms of access to prescription drugs, popularity and prices of prescription medications on the street, as well as the initiation and progression of prescription and illicit drug abuse. RESULTS: The primary sources of prescription drugs on the street were the elderly, patients with pain, and doctor shoppers, as well as pill brokers and dealers who work with all of the former. The popularity of prescription drugs in the street market was rooted in the abusers' perceptions of these drugs as 1) less stigmatizing; 2) less dangerous; and, 3) less subject to legal consequences than illicit drugs. For many, the abuse of prescription opioids also appeared to serve as a gateway to heroin use. CONCLUSION: The diversion of prescription opioids might be reduced through physician education focusing on 1) recognizing that a patient is misusing and/or diverting prescribed medications; 2) considering a patient's risk for opioid misuse before initiating opioid therapy; and 3) understanding the variation in the abuse potential of different opioid medications currently on the market. Patient education also appears appropriate in the areas of safeguarding medications, disposal of unused medications, and understanding the consequences of manipulating physicians and selling their medications.

Examination of an interventionist-led HIV intervention among criminal justice-involved female prisoners.

The purpose of this study was to examine the implementation, adherence and protocol fidelity for the Reducing Risky Relationships for HIV (RRR-HIV) study. The RRR-HIV study is a phase III trial of a randomized intervention to reduce human immunodeficiency virus (HIV) risk behaviors among incarcerated women in four US states: Connecticut, Delaware, Kentucky and Rhode Island. The intervention consists of five interventionist-led prison-based group sessions and a sixth individual community-based session. Data on adherence, implementation, acceptability and fidelity of the intervention were obtained from forms completed after the five prison-based sessions by both the interventionist and participant. Data from the sixth session were collected by the interventionist. Of the 363 women recruited to date, 173 (47.6%) have been randomly allocated to the experimental RRR intervention, of which implementation measures were available for 162 (93.6%). Almost three-quarters of women attended all five sessions, each of which lasted a median of 90 minutes, indicating successful implementation of the protocol across multiple study sites. Interventionists and participants alike reported that all of the topics for each session were discussed, suggesting adherence to the protocol. In addition, protocol interventionists indicated that more than 95% of the women were engaged/involved, interested, and understood the materials presented, indicating high levels of acceptability among the participants and fidelity to the intervention protocols. The majority of participants also answered all of the post-test questions correctly, which is another strong indicator of the fidelity to the intervention. Results suggest that the RRR-HIV study has been successfully implemented across multiple study sites. Adherence to the protocol, as well as protocol fidelity and acceptability, were also strong, which is essential to establish prior to examining outcome data.

Tri-city study of Ecstasy use problems: a latent class analysis.

This study used latent class analysis to examine distinctive subtypes of Ecstasy users based on 24 abuse and dependence symptoms underlying standard DSM-IV criteria. Data came from a three site, population-based, epidemiological study to examine diagnostic nosology for Ecstasy use. Subject inclusion criteria included lifetime Ecstasy use exceeding five times and once in the past year, with participants ranging in age between 16 and 47 years of age from St. Louis, Miami, U.S. and Sydney, Australia. A satisfactory model typified four latent classes representing clearly differentiated diagnostic clusters including: (1) a group of sub-threshold users endorsing few abuse and dependence symptoms (negatives), (2) a group of 'diagnostic orphans' who had characteristic features of dependence for a select group of symptoms (mild dependent), (3) a 'transitional group' mimicking the orphans with regard to their profile of dependence also but reporting some abuse symptoms (moderate dependent), and (4) a 'severe dependent' group with a distinct profile of abuse and dependence symptoms. A multinomial logistic regression model indicated that certain latent classes showed unique associations with external non-diagnostic markers. Controlling for demographic characteristics and lifetime quantity of Ecstasy pill use, criminal behavior and motivational cues for Ecstasy use were the most efficient predictors of cluster membership. This study reinforces the heuristic utility of DSM-IV criteria applied to Ecstasy but with a different collage of symptoms that produced four distinct classes of Ecstasy users.

Integrating an HIV/HCV brief intervention in prisoner reentry: results of a multisite prospective study.

Brief interventions to reduce harmful or problem behaviors have become increasingly popular in a variety of health fields, including HIV and hepatitis risk reduction. A central issue in intervention research involves the evaluation of what constitutes an effective "dose" of an intervention. This research examines the relative effectiveness of three alternative brief interventions of varying intensity designed to change the risk behaviors of inmates who are reentering society: a DVD-based, peer delivered intervention; the NIDA Standard HIV Intervention; and a standard practice condition (HIV educational video). All participants randomly received one of the interventions and were tested for HIV and HCV prior to release from custody. Thirty and ninety-day follow-ups examined changes in high-risk behaviors. Results reported here for 343 subjects who have completed the 90-day follow up indicate significant reductions in reported sexual risk behaviors for those participating the DVD intervention, compared to the other two brief interventions. This study is among the first to report any positive impacts on sexual behaviors among a population of inmates returning to the community.

Partner relationships and HIV risk behaviors among women offenders.

The HIV infection rate is increasing among women in general and for female inmates specifically (Maruschak 2004), which makes understanding the correlates of risky sexual behaviors critical for this population. Partner relationships, particularly the extent to which women perceive they have power within the relationship, may be important in modeling risk behaviors. Few studies have considered the association between relationship power and HIV risk behaviors among women offenders. This study examines women's perceptions of their relationships using the Sexual Relationship Power Scale (Pulerwitz, Gortmaker, & DeJong 2000) and NIDA's HIV Risk Behavior Assessment (NIDA 1995). Data were collected from female inmates in four prisons as part of the Reducing Risky Relationships for HIV protocol being conducted through the NIDA's Criminal Justice Drug Abuse Treatment Studies (CJ-DATS) cooperative agreement. Women reported whether they had engaged in five types of unprotected sex in the month prior to incarceration. Logistic regression models of the associations between relationship power and five types of unprotected sex revealed some support for the importance of power as a protective factor in reducing the odds of unprotected sexual behaviors. Implications and findings are presented to add to understanding of partner relationships and HIV risk behaviors.

Trends in the use and abuse of branded and generic extended release oxycodone and fentanyl products in the United States.

BACKGROUND: A great deal of previous work on the pharmacoeconomics of alcohol, tobacco and illicit drug abuse indicates that as cost decreases, abuse increases and vice versa. The application of these cost principles to the abuse of prescribed medications is largely unknown. In this paper we assessed whether the introduction of generic products in the U.S. increased the therapeutic use and illicit abuse of extended release oxycodone products and the fentanyl patch. METHODS: As an index of therapeutic use, we purchased prescription data for each of the ZIP codes in which we had corresponding abuse data. To gather information about prescription drug abuse, we elicited cases with quarterly questionnaires completed by a key informant network. RESULTS: The introduction of generic extended release (ER) oxycodone and fentanyl patch did not significantly change the total prescriptions written for these products, but markedly altered the composition of sales: branded sales dropped precipitously over a very short time and this was compensated for by a corresponding increase in sales of generics. Surprisingly, the introduction of generic products did not increase the abuse of ER oxycodone or fentanyl products; the branded version was the drug of choice for at least 2 years. CONCLUSIONS: Our data suggest that drug costs alone do not increase the overall likelihood that a prescription opioid analgesic will be used therapeutically or abused. However, while generics are rapidly endorsed by insurance companies as a prescribed entity, abuse of the branded versions of ER oxycodone and fentanyl remains predominant for some time.

Predictors of substance abuse treatment entry for crime-involved, cocaine-dependent women.

A health services utilization model was used to examine predictors of treatment entry among a large sample (N=659) of crime-involved, cocaine-dependent women. Previous research in this area has focused on women already in treatment and resultantly excluded a critical population of drug-dependent women who are actively using but not in treatment. Thus, interviews were completed with women who were participating in substance abuse treatment programs and with women who were not currently in treatment to examine what factors may have inhibited or facilitated their entering treatment. The predisposing characteristics, enabling resources, and service needs of these women were assessed in relation to their treatment utilization status. Findings indicated that variables within each of the three categories of the health services model were related to treatment entry including race/ethnicity and education (predisposing characteristics), and alcohol use and having multiple chronic health problems (need). But, overall, enabling factors, such as being legally employed, having health insurance, having custody of children, and knowing where to go to get treatment, appeared to be the most influential predictors. Implications of this research include employing multiple tactics for increasing the likelihood of treatment entry such as aggressive outreach efforts focusing on at-risk women who have the fewest social ties and who are the least integrated into mainstream society.

Foundations of opioid risk management.

Increased abuse and diversion of prescription opioids has been a consequence of the increased availability of opioids to address the widespread problem of undertreated pain. Opioid risk management refers to the effort to minimize harms associated with opioid therapy while maintaining appropriate access to therapy. Management of these linked public health issues requires a coordinated and balanced effort among a disparate group of stakeholders at the federal, state, industry, practitioner, and patient levels. This paper reviews the principles of opioid risk management by examining the epidemiology of prescription opioid abuse in the United States; identifying key stakeholders involved in opioid risk management and their responsibilities for managing or monitoring opioid abuse and diversion; and summarizing the mechanisms currently used to monitor and address prescription opioid abuse. Limitations of current approaches, and emerging directions in opioid risk management, are also presented.

Brazilian female crack users show elevated serum aluminum levels.

OBJECTIVE: There is no information in the literature on the impact of crack smoking using crushed aluminum cans as makeshift pipes, a common form of crack use in Brazil. Since aluminum intake is associated with neurological damage, we measured serum aluminum levels in crack smokers. The objective of this study was to ascertain the levels of aluminum in crack users who smoke on makeshift aluminum pipes. METHOD: 71 female crack smokers, their mean age being 28.0 (+/- 7.7), provided information about their drug use, and had blood samples tested for serum aluminum level. RESULTS: 56 (79%) subjects smoked crack from crushed can pipes, while 15 (21%) smoked from other containers. Fifty-two (73.2%) out of the 71 subjects presented a serum aluminum level of 2 microg/l and 13 (18.3%) had a serum aluminum level of 6 microg/l cut-off point, which is above the reference value. When compared to non-drug users matched by their mean age and gender, they had similar median values and interquartile ranges for serum aluminum level [3 (2-4.6) for crack smokers; 2.9 (1.6-4.1) for controls], but with different means and standard deviations (4.7 +/- 4.9 and 2.9 +/- 1.7, respectively). DISCUSSION: Crack smokers have high serum aluminum level, but we are unsure of its complete association with aluminum cans. Further studies are needed. If such association is proven true in future research, further issues will be raised in dealing with this important disorder, including proper planning and evaluation of public health policies in this area.

Using thought mapping and structured stories to decrease HIV risk behaviors among cocaine injectors and crack smokers in the South of Brazil.

OBJECTIVES: To compare changes in AIDS knowledge and risk behaviors among Brazilian cocaine users in an intervention trial. METHOD: 119 participants were randomly assigned to either a standard or a standard plus "thought mapping" intervention, and re-interviewed 2 and 8 weeks after intake using standardized data collection instruments. Intervention effects were examined using generalized estimated equation model. RESULTS: Significant increases in AIDS knowledge and condom use were observed in the experimental group, as well as significant changes in the subscores for sexual and drug risks. The experimental intervention was less successful in decreasing mean days of cocaine use when compared to the standard. CONCLUSION: Although not robust, the findings nevertheless suggest that components of the experimental thought-mapping model might be useful in combination with other approaches.

A comparison of the abuse liability of tramadol, NSAIDs, and hydrocodone in patients with chronic pain.

Concern about abuse/dependence in chronic pain patients taking opioid analgesics may lead to undertreatment of pain, yet little is known about the prevalence of abuse/dependence in these patients and how it differs among analgesic agents. The objective of this study was to assess the prevalence of tramadol abuse compared to nonsteroidal anti-inflammatory drugs (NSAIDs) and hydrocodone-containing analgesics in patients with chronic noncancer pain (CNP). The study had three arms. The first arm consisted of subjects prescribed tramadol alone; the second of subjects randomized to either NSAIDs or tramadol; and the third of subjects randomized to hydrocodone or tramadol. Each investigator received two boxes of prescriptions randomized so that one in every four prescriptions was for tramadol. Upon deciding on the therapeutically appropriate arm, the physician selected the appropriate box, opened the next envelope and completed the enclosed prescription. After the initial randomization, physicians could prescribe whatever medication was therapeutically appropriate. A total of 11,352 subjects were enrolled. Up to nine interviews using a structured questionnaire were conducted over a 12-month period. An algorithm called the "Abuse Index" was developed to identify subjects who were abusing the drug. The primary components of the index were increasing dose without physician approval, use for purposes other than intended, inability to stop its use, and withdrawal. The percent of subjects who scored positive for abuse at least once during the 12-month follow-up were 2.5% for NSAIDs, 2.7% for tramadol, and 4.9% for hydrocodone. When more than one hit on the algorithm was used as a measure of persistence, abuse rates were 0.5% for NSAIDs, 0.7% for tramadol, and 1.2% for hydrocodone. Thus, the results of this study suggest that the prevalence of abuse/dependence over a 12-month period in a CNP population that was primarily female was equivalent for tramadol and NSAIDs, with both significantly less than the rate for hydrocodone.

The Diversion of Ultram, Ultracet, and generic tramadol HCL.

Ultram (tramadol HCL) was approved by the Food and Drug Administration in 1994 as a non-scheduled drug under the Controlled Substance Act. The non-scheduled status was contingent on the development and implementation of a comprehensive post-marketing surveillance program by an Independent Steering Committee external to Ortho-McNeil Pharmaceutical charged with monitoring abuse and recommending scheduling if unexpectedly high abuse occurred. The program developed by this committee was composed of a variety of studies, and the results of the first three years of the surveillance efforts revealed that the rate of Ultram abuse was low. At a meeting of the FDA in 1998 to reexamine the scheduling status of Ultram, it was recommended that the scope of the postmarketing surveillance program be broadened to include data on diversion. After a 1-year pilot study, by January 2002, a nationwide diversion survey was fully operational. This brief communication describes the experiences of this diversion study, and compares the findings on the diversion of Ultram and other tramadol HCL products with that of more widely abused drugs. Survey data suggest that the diversion of Ultram and other tramadol products is low, and overall, diversion investigators did not consider tramadol to be a problem in their respective jurisdictions.

Changing patterns of cocaine use and hiv risks in the south of Brazil.

For well over a decade, researchers in Porto Alegre, Brazil, have been documenting the extent of the AIDS epidemic in the region, with a specific focus on the linkages between drug use and HIV seropositivity. Virtually all of the studies conducted during those years found injection drug use (IDU) to be the major vector for HIV seropositivity in this population. However, recent research found that the number of IDUs had declined significantly. Qualitative interviews and focus groups suggested many reasons for this decline: (1) many had died, because they had never heard of AIDS or HIV, and were unaware of how HIV is transmitted. As a result, they had become infected through the sharing of injection paraphernalia. (2) The quality of street cocaine had declined, making injection difficult. (3) Because of a fear of AIDS, some shifted to the smoking of crack, which had become a newly availability commodity in the street culture. Within this context, this article describes the qualitative data describing the decline of cocaine injecting and the corresponding emergence of crack use in Porto Alegre, Brazil, and related HIV risks.

Trends in abuse of Oxycontin and other opioid analgesics in the United States: 2002-2004.

UNLABELLED: OxyContin (Purdue Pharma L.P., Stamford, Conn) was approved by the Food and Drug Administration (FDA) in 1995 as a sustained-release preparation of oxycodone hydrochloride and was thought to have much lower abuse potential than immediate-release oxycodone because of its slow-release properties. However, beginning in 2000, widespread reports of OxyContin abuse surfaced. In response, Purdue Pharma L.P. sponsored the development of a proactive abuse surveillance program, named the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS) system. In this paper, we describe results obtained from one aspect of RADARS--the use of drug abuse experts (ie, key informants)--as a source of data on the prevalence and magnitude of abuse of prescription drugs. The results indicate that prescription drug abuse has become prevalent, with cases reported in 60% of the zip codes surveyed. The prevalence of abuse was rank ordered as follows: OxyContin >or= hydrocodone > other oxycodone > methadone > morphine > hydromorphone > fentanyl > buprenorphine. In terms of the magnitude of abuse (>or=5 cases/100,000 persons in a 3-digit zip code), modest growth was seen with all analgesics over the 10 calendar quarters we monitored, but was most pronounced with OxyContin and hydrocodone. These results indicate that OxyContin abuse is a pervasive problem in this country, but that it needs to be considered in the context of a general pattern of increasing prescription drug abuse. PERSPECTIVE: Over the past 5 years, there have been reports, frequently anecdotal, that opioid analgesic abuse has evolved into a national epidemic. In this study, we report systematic data to indicate that opioid analgesic abuse has in fact increased among street and recreational drug users, with OxyContin and hydrocodone products the most frequently abused. Steps need to be taken to reduce prescription drug abuse, but very great care needs to be exercised in the nature of these actions so the legitimate and appropriate use of these drugs in the treatment of pain is not compromised as a result.

Treatment during transition from prison to community and subsequent illicit drug use.

This study examined the effects of postrelease transitional therapeutic community treatment on the drug use and employment rates of drug involved prisoners in the Delaware corrections system followed for up to 5 years after release. A comparison group received standard postrelease supervision. Abstinence rates were 32.2% in the treatment group and 9.9% in the no-treatment group, and the treatment group had a higher overall proportion of time free of drug use. Time to relapse was a mean of 28.8 months in the treatment group versus 13.2 months in the no-treatment group. Relapse was defined as any use of any drug and was confirmed by urinalysis. Positive effects were seen even for those who did not complete treatment. The treatment group had a significantly higher rate of employment after leaving work release (54.6%) than did the no-treatment group (45.4%). Treatment during the transitional period between prison and community showed substantial and persistent benefits even for a cohort marked with extensive criminal history, low rates of marital bonds, and substantial unemployment.

Prescription drug abuse among ecstasy users in Miami.

This study examines the nature, extent and consequences of prescription drug abuse among 143 ecstasy users in Miami. Participants were recruited through nightclub and college campus outreach, and through respondent referrals. Instrumentation included the Risk Behavior Assessment, Substance Abuse Module and Center for Epidemiological Studies Depression Scale. Median age was 23, 42% were female and 50% Hispanic. An arrest history was reported by 44%, and 33% reported prior drug/alcohol treatment. Prescription drug abuse was reported by 87%; alprazolam (57%), oxycodone (36%), hydrocodone (32%) and diazepam (30%) were cited most often. Prescription drug abusers were more likely to report polydrug use, drug treatment histories, risky drug use behaviors, and symptoms of depression. They also reported numerous physical, psychological and social consequences of prescription drug abuse. Additional studies among larger samples are needed to understand the processes of prescription drug access and the extent of integration in club drug using cultures.
