Quality of life of patients treated with opium tincture or methadone: A randomized controlled trial.

OBJECTIVE: Quality of life (QoL) is an increasingly recognized patient-centered treatment outcome in individuals with opioid use disorder. There is a gap in literature on the impact of opium tincture (OT) on patients' QoL compared to standard treatment options such as methadone. This study aimed to compare the QoL of participants with opioid use disorder receiving OAT using OT or methadone and identify the factors associated with their QoL during treatment. METHODS: The opium trial was a multicenter non-inferiority randomized clinical trial in four private OAT outpatient clinics in Iran. The study assigned patients to either OT (10 mg/ml) or methadone sirup (5 mg/ml) for a follow-up of 85 days. QoL was assessed using the brief version of the World Health Organization Quality of Life instrument (WHOQOL- BREF). RESULTS: A total of 83 participants, 35 (42.2%) in the OT arm and 48 (57.8%) in the methadone arm, completed the WHOQOL-BREF in full and were included in the primary analysis. The mean score of patients' QoL showed improvement compared to baseline, but differences were not statistically significant between OT and methadone arms (p = 0.786). Improvements were mainly observed within the first 30 days of receiving treatment. Being married and lower psychological distress were associated with an improved QoL. Within the social relationships domain, male gender showed significantly higher QoL compared to females. CONCLUSION: OT shows promise as an OAT medication, comparable to methadone in improving patients' QoL. There is a need to incorporate psychosocial interventions to further sustain and improve the QoL in this population. Identifying other social determinants of health which affect QoL and the cultural adaptation of assessments for individuals from various ethnocultural backgrounds are critical areas of inquiry.

Pain, psychological flexibility, and continued substance use in a predominantly hispanic adult sample receiving methadone treatment for opioid use disorder.

BACKGROUND: We explored pain, psychological flexibility, and continued substance use among 100 adults treated with methadone for opioid use disorder (OUD). All participants had co-occurring chronic pain. METHODS: Participants recruited from a community treatment center between 2009 and 2010 completed an interviewer-facilitated assessment. Chronic pain severity and interference, psychological flexibility (mindfulness, acceptance, values success), past 30-day substance use, and demographics were reported. We modeled a zero-inflated negative binomial regression to examine 1) the probability that an individual does not use illicit substances and 2) illicit substance use frequency among those expected to use. Pain severity and mindfulness were included as predictors in the logit (zero inflated) model. Pain interference, acceptance, and values success were included as predictors in the negative binomial (count) model. We controlled for age and gender in both models. RESULTS: Participants were predominantly (84%) Hispanic, and 64% used an illicit substance least once in the past 30 days. Greater degree of mindfulness significantly predicted the probability that an individual does not continue to use illicit substances (OR = 1.59, p < 0.05). Lower degree of values success significantly predicted greater illicit substance use frequency among those likely to use (IRR = 0.72, p < 0.01). No other variables were associated with continued substance use. CONCLUSIONS: Findings suggest psychological flexibility is associated with continued substance use in this predominantly Hispanic sample of adults treated for OUD with co-occurring chronic pain. Study findings may have implications for how to address the treatment needs of this complex population.

Treatment for Individuals With Severe Mental Illness Who Use Illicit Drugs While Maintained on Methadone: Mindfulness and Modification Therapy.

Substantial research has noted the serious consequences of 1) co-occurring severe mental illness (SMI) and substance use disorders, and 2) use of illicit drugs while maintained on methadone for opioid dependence. However, treatment needs of individuals who meet both of the above criteria remain largely unmet. This pilot study investigated the feasibility and acceptability of a 12-week, transdiagnostic group therapy (mindfulness and modification therapy [MMT]) tailored for opioid-dependent individuals (N = 6) with SMI and illicit drug use. Retention was 83%. At posttreatment and 2-month follow-up, participants rated the treatment as highly helpful (9 of 10; 8.67 of 10, respectively), reported routinely practicing the guided-mindfulness exercises, and reported high confidence that they would continue to practice. Assessments revealed clinically meaningful decreases in reported days of illicit drug use at posttreatment and follow-up, with large effect sizes. Preliminary evidence suggests that MMT may be a feasible and acceptable therapy that may improve treatment engagement in this underserved population.

Specificity of personality relationships to particular forms of concurrent substance use among methadone maintenance therapy clients.

OBJECTIVE: A mainstay treatment for opioid addiction in North America is methadone maintenance therapy (MMT) - a form of opiate agonist therapy (OAT). While efficacious for treating opioid addiction, MMT fails to address the concurrent polysubstance use that is common among opioid dependent clients. Moreover, psychosocial approaches for addressing polysubstance use during MMT are lacking. Our study's goals were to validate the use of the four-factor personality model of substance use vulnerability in MMT clients, and to demonstrate theoretically-relevant relationships of personality to concurrent substance use while receiving MMT. METHOD: Respondents included 138 daily-witnessed MMT clients (65.9% male, 79.7% Caucasian), mean age (SD) 40.18 (11.56), recruited across four Canadian MMT clinics. Bayesian confirmatory factor analysis was used to establish the structural validity of the four-factor personality model of substance use vulnerability (operationalized with the Substance Use Risk Profile Scale [SURPS]) in MMT clients. SURPS personality scores were then used as predictors for specific forms of recent (past 30-day) substance use. RESULTS: Using a latent hierarchal model, hopelessness was associated with recent opioid use; anxiety sensitivity with recent tranquilizer use; and sensation seeking with recent alcohol, cannabis, and stimulant use. CONCLUSION: Personality is associated with substance use patterns and may be an appropriate target for intervention for those undergoing MMT to reduce opioid use, and potentially dangerous concurrent use of other drugs, while receiving methadone.

The Effectiveness of Group Spiritual Intervention on Self-esteem and Happiness Among Men Undergoing Methadone Maintenance Treatment.

BACKGROUND: Drug dependence or substance use disorder not only affects a person's life but also brings a lot of challenges for families and communities and imposes heavy burdens on them. There are various therapies in the domain of addiction whose main purposes are to reduce or to cut down substance abuse. OBJECTIVE: This study aimed to determine the effectiveness of group spiritual intervention on selfesteem and happiness among male clients undergoing methadone maintenance treatment. METHODS: This study was an intervention study in which 60 clients affected with substance abuse and undergoing methadone maintenance treatment were recruited. The study samples were selected through convenience sampling method and then divided randomly into two groups of 30 individuals: intervention and control. The intervention group attended group spiritual interventions for 10 sessions. Self-esteem and happiness among the study participants were also measured through Coopersmith Self-Esteem Inventory and Oxford Happiness Questionnaire before and after the intervention. RESULTS: The results showed a significant difference between both intervention and control groups in terms of self-esteem and happiness (P < 0.05); so that the participants in the intervention group demonstrated a significant improvement in their self-esteem and happiness. CONCLUSION: It was concluded that group spiritual intervention as a useful method could be effective in enhancing self-esteem and happiness among addicted individuals undergoing methadone maintenance treatment. The given treatment could be also used as a complementary therapy beside methadone maintenance treatment to reduce the likelihood of people returning to substance abuse.

Three-year retention in methadone opioid agonist treatment: A survival analysis of clients by dose, area deprivation, and availability of alcohol and cannabis outlets.

OBJECTIVE: To determine the effect of clinical, socio-demographic, and contextual characteristics on treatment retention in an opioid treatment program (OTP). METHODS: A retrospective longitudinal review of 851 clients who received methadone at the only state-funded OTP in Spokane County, Washington between 2015 and 2017. A time variable (the number of days in treatment) and a status indicator (to distinguish between clients who dropped out or censored) worked together to define retention in treatment. Our hypothesized covariates included: area deprivation, distance to the OTP, availability of cannabis retail outlets, availability of on-premise and off-premise alcohol outlets, methadone dosage, age, gender, race, and years on treatment. Cox regression within the family of survival analysis was used to model time-to-event data in the presence of censored cases. RESULTS: The median duration of retention was 394 (95%CI = 324-464) days. In the multivariable Cox regression, factors predicting treatment retention were area deprivation (HR = 1.79, 95%CI = 1.02-3.15, p = 0.04), age (HR=0.99, 95%CI=0.98-.99, p = 0.008), dosage of methadone (HR=0.98, 95%CI=0.98-0.98, p < 0.001), and the number of years on treatment (HR=1.12, 95%CI=1.06-1.18, p < 0.001). CONCLUSIONS: The findings of this study showed age and methadone dosage were protective factors and area deprivation and years on treatment were risk factors for treatment retention. After dichotomizing methadone dosage, a unique finding of this study was that higher dosage of methadone did not lead to increasingly smaller HRs for dropping out of treatment. Considering that opioid use disorder is a chronic condition, efforts need to be made to target factors associated with retention.

Overcoming medication stigma in peer recovery: A new paradigm.

BACKGROUND: Treatment for opioid use disorder involving opioid-based pharmacotherapies is considered most effective when accompanied by psychosocial interventions. Peer-led support groups are widely available and have been described by many as fundamental to the recovery process. However, some individuals using medications face stigma in these settings, which can be contradictory and counterproductive to their recovery. METHODS: This paper describes the development of the "Ability, Inspiration and Motivation" or "AIM" group, an alternative peer support group that aims to remove medication stigma from peer recovery. Qualitative interviews with staff, peers, and clients of a community-based buprenorphine treatment program were used to establish the core components of the curriculum to support client needs. RESULTS: Staff, peers, and clients of the buprenorphine program indicated a need and desire to establish a peer recovery group that recognizes persons on medication as being in recovery and destigmatizes use of medication to treat opioid addiction. A respectful environment, holistic perspective on health, spirituality, sharing, and celebration were all established as necessary pillars of the AIM group curriculum. CONCLUSIONS: The community-based effort to establish and develop the AIM group demonstrates that combining the strengths of a peer support with evidence-based medication treatment is both possible and desirable. Shifting the culture of peer recovery groups to support the use of medications may have implications for improving treatment retention and should be considered as a potential strategy to reduce the burden of the opioid epidemic.

Dietary Intake Among Opioid- and Alcohol-Using Pregnant Women.

BACKGROUND: Substance abuse in nonpregnant adults has been associated with increased intake in calories and decreased intake of nutrient-dense foods; however, studies examining dietary intake in opioid-using and alcohol-using pregnant women are lacking. OBJECTIVE: The objective of this study was to evaluate dietary intake in opioid-using pregnant women with or without concurrent light-to-moderate alcohol use as compared to abstaining controls. METHODS: This prospective birth cohort included 102 pregnant women classified into four study groups: controls (n = 27), medication-assisted treatment (MAT; n = 26), alcohol (ALC; n = 22), and concurrent use of both substances (MAT + ALC; n = 27). Percentage differences in macro- and micronutrient intake were estimated from the food frequency questionnaire and compared among the study groups. Proportions of participants with intakes below the estimated average requirements (EAR) based on diet and diet with supplements were estimated. RESULTS: Three exposed groups had lower prevalence of multivitamin use in periconceptional period (11.5-31.8%) than controls (44.4%). Unadjusted mean energy intake was significantly higher in the MAT + ALC group compared to controls, while micronutrient intake per 1000 kcal was the highest in the control group for almost all of the micronutrients analyzed. After adjustment for energy intake and sociodemographic characteristics, MAT group had lower estimated dietary intake of iron (-15.0%, p = 0.04) and folate (-16.8%, p = 0.04) compared to controls. A high proportion of participants in all study groups had dietary intake below the EAR for vitamin E, iron, and folate. CONCLUSION: Results highlight the need for targeted dietary interventions for opioid-using pregnant women.

Why People Who Inject Drugs Voluntarily Transition Off Methadone in Ukraine.

Methadone maintenance therapy (MMT) treats opioid use disorder among people who inject drugs (PWID). To understand why PWID may voluntarily discontinue MMT, we analyzed data from 25 focus groups conducted in five Ukrainian cities from February to April 2013 with 199 participants who were currently, previously, or never on MMT. Using constant comparison method, we uncovered three themes explaining why PWID transition off MMT: (a) purposeful resistance to rigid social control associated with how MMT is delivered and to power asymmetries in provider-patient relationships, (b) self-management of a PWID's "wounded identity" that is common in socially stigmatized and physically sick persons-MMT serves as a reminder of their illness, and (c) the quest for a "normal life" uninterrupted by daily MMT site visits, harassment, and time inefficiencies, resources, and social capital. Focusing on holistic principles of recovery would improve addiction treatment and HIV prevention in Ukraine and globally.

Primary healthcare-based integrated care with opioid agonist treatment: First experience from Ukraine.

BACKGROUND: Ukraine's HIV epidemic is concentrated among people who inject drugs (PWID), however, coverage with opioid agonist therapies (OATs) available mostly at specialty addiction clinics is extremely low. OAT integrated into primary healthcare clinics (PHCs) provides an opportunity for integrating comprehensive healthcare services and scaling up OAT. METHODS: A pilot study of PHC-based integrated care for drug users conducted in two Ukrainian cities between 2014 and 2016 included three sub-studies: 1) cross-sectional treatment site preference assessment among current OAT patients (N=755); 2) observational cohort of 107 PWID who continued the standard of care versus transition of stabilized and newly enrolled PWID into PHC-based integrated care; and 3) pre/post analysis of attitudes toward PWID and HIV patients by PHC staff (N=26). RESULTS: Among 755 OAT patients, 53.5% preferred receiving OAT at PHCs, which was independently correlated with convenience, trust in physician, and treatment with methadone (vs. buprenorphine). In 107 PWID observed over 6 months, retention in treatment was high: 89% in PWID continuing OAT in specialty addiction treatment settings (standard of care) vs 94% in PWID transitioning to PHCs; and 80% among PWID newly initiating OAT in PHCs. Overall, satisfaction with treatment, subjective self-perception of well-being, and trust in physician significantly increased in patients prescribed OAT in PHCs. Among PHC staff, attitudes towards PWID and HIV patients significantly improved over time. CONCLUSIONS: OAT can be successfully integrated into primary care in low and middle-income countries and improves outcomes in both patients and clinicians while potentially scaling-up OAT for PWID.

Anxiety disorders are associated with early onset of heroin use and rapid transition to dependence in methadone maintained patients.

Early onset of heroin use is a severity marker of heroin use disorder. We studied the interaction between early onset and rapid transition to heroin dependence recorded with retrospective interviews in 213 patients with severe heroin dependence and history of methadone maintenance treatment. General linear models were used to identify independent factors associated with early onset, factors associated with rapid transition to dependence, and a multivariate model was used to study the interaction of those two dimensions. Lifetime history of anxiety disorders and age at onset of cannabis use are shared common risk factors and are associated with the interaction.

Methadone, buprenorphine and preferences for opioid agonist treatment: A qualitative analysis.

BACKGROUND: Patients and clinicians have begun to recognize the advantages and disadvantages of buprenorphine relative to methadone, but factors that influence choices between these two medications remain unclear. For example, we know little about how patients' preferences and previous experiences influence treatment decisions. Understanding these issues may enhance treatment engagement and retention. METHODS: Adults with opioid dependence (n=283) were recruited from two integrated health systems to participate in interviews focused on prior experiences with treatment for opioid dependence, knowledge of medication options, preferences for treatment, and experiences with treatment for chronic pain in the context of problems with opioids. Interviews were audio-recorded, transcribed verbatim, and coded using Atlas.ti. RESULTS: Our analysis revealed seven areas of consideration for opioid agonist treatment decision-making: (1) awareness of treatment options; (2) expectations and goals for duration of treatment and abstinence; (3) prior experience with buprenorphine or methadone; (4) need for accountability and structured support; (5) preference to avoid methadone clinics or associated stigma; (6) fear of continued addiction and perceived difficulty of withdrawal; and (7) pain control. CONCLUSION: The availability of medication options increases the need for clear communication between clinicians and patients, for additional patient education about these medications, and for collaboration and patient influence over choices in treatment decision-making. Our results suggest that access to both methadone and buprenorphine will increase treatment options and patient choice and may enhance treatment adherence and outcomes.

Patient Satisfaction with Methadone Maintenance Treatment in Vietnam: A Comparison of Different Integrative-Service Delivery Models.

BACKGROUND: Patient satisfaction is an important component of quality in healthcare delivery. To inform the expansion of Methadone Maintenance Treatment (MMT) services in Vietnam, we examined the satisfaction of patients with regards to different services delivery models and identified its associated factors. METHODS: We interviewed 1,016 MMT patients at 5 clinics in Hanoi and Nam Dinh province. The modified SATIS instrument, a 10-item scale, was used to measure three dimensions: "Services quality and convenience", "Health workers' capacity and responsiveness" and "Inter-professional care". RESULTS: The average score was high across three SATIS dimensions. However, only one third of patients completely satisfied with general health services and treatment outcomes. Older age, higher education, having any problem in self-care and anxiety/depression were negatively associated with patient's satisfaction. Meanwhile, patients receiving MMT at clinics, where more comprehensive HIV and general health care services were available, were more likely to report a complete satisfaction. CONCLUSION: Patients were highly satisfied with MMT services in Vietnam. However, treatment for drug users should go beyond methadone maintenance to address complicated health demands of drug users. Integrating MMT with comprehensive HIV and general health services together with improving the capacity of health workers and efficiency of services organisation to provide interconnected health care for drug users are critical for improving the outcomes of the MMT program.

Variations in Cannabis Use Level and Correlates in Opiate-Users on Methadone Maintenance Treatment: A French Prospective Study.

INTRODUCTION: Concurrent cannabis use is very frequent among opioid users on methadone maintenance treatment (MMT), which could reflect a coping strategy during MMT. The aims of this study were to describe variations in cannabis use and to explore whether MMT could modify the patterns of cannabis use correlates. METHODS: The sample included 188 opioid-dependent individuals who initiated MMT and were prospectively followed for 12 months. Cannabis use was monitored at enrollment and at months 3, 6 and 12. The relationships between cannabis use level (non-daily use and daily use vs. no use in the previous month) and its determinants (socioeconomic factors, substance use characteristics and mental health) were explored using mixed multinomial logistic regressions. RESULTS: No significant variation trend in cannabis use levels was observed during the follow-up period among the 188 subjects analyzed (p=0.85). After adjustment for socio-demographic factors, opioid use was associated with both non-daily (OR=3.11, p=0.01) and daily cannabis use (OR=2.58, p=0.04). Moreover the number of health problems reported was associated with daily cannabis use (OR=1.12 per 1-problem increase, p=0.004). The factors associated with cannabis use appeared similar before and after starting treatment (no significant interaction observed between MMT and any factor). CONCLUSIONS: Cannabis use during MMT more likely reflects pre-existing common liability to substance use or self-medication practices towards health problems than a behavior aimed at managing problems with MMT. With recent research suggesting an interaction between cannabinoid and opioid systems, the benefit of cannabis-based pharmacotherapies during MMT should be further explored in addiction research.

Opioid addicted buprenorphine injectors: drug use during and after 12-weeks of buprenorphine-naloxone or methadone in the Republic of Georgia.

AIMS: The aim of this study is to assess the prevalence of non-opioid drug use among opioid-addicted, buprenorphine injecting individuals in Georgia, during and after a 12-week course of buprenorphine-naloxone (Suboxone®) or methadone. METHODS: Randomized controlled trial with daily observed Suboxone® or methadone and weekly counseling, urine tests and timeline followback (TLFB) in weeks 0-12 and 20, and the Addiction Severity Index (ASI) at weeks 0, 4, 8, 12, 20. RESULTS: Of the 80 patients (40/group, 4 women), 68 (85%) completed the 12-weeks of study treatment and 66 (82.5%) completed the 20-week follow-up. At baseline, injecting more than one drug in the last 30 days was reported by 68.4% of patients in the methadone and 72.5% in the Suboxone® groups. Drug use was markedly reduced in both treatment conditions but there were significant differences in the prevalence of specific drugs with more opioid (1.5 vs. 0.2%; p=0.03), less amphetamine (0.2 vs. 2.8%; p<0.001) and less marijuana (1.7 vs. 10.2%; p<0.001) positive urine tests in the methadone vs. Suboxone® groups. At the 20-week follow-up, TLFB results on the 34 that continued methadone or the 3 on Suboxone® showed less opioid (5.6 vs. 27.6%; p<0.001), illicit buprenorphine (2.7 vs. 13.8%; p=0.005), benzodiazepine (13.5 vs. 34.5%; p<0.001), and marijuana (2.8 vs. 20.7%; p<0.001) use than the 29 who did not continue opioid substitution therapy. CONCLUSIONS: Despite small but significant differences in opioid and other drug use, both treatments were highly effective in reducing opioid and non-opioid drug use.

Factors affecting noncompliance with buprenorphine maintenance treatment.

BACKGROUND: The current study aimed to identify risk factors for treatment noncompliance in a sample of veterans receiving buprenorphine/naloxone for an opioid use disorder. METHODS: Records from all patients who are currently or had previously been maintained on buprenorphine in the buprenorphine maintenance treatment program at the Atlanta VA Medical Center during the years 2006 to 2013 were evaluated. Of the 209 patients treated in the clinic between 2006 and 2013, 140 were excluded from the study because they did not have a call-back done at the time of data collection. Thus, 69 patient charts were selected for review. RESULTS: The multiple linear regression analysis of the predictable variables for noncompliance with the buprenorphine pill count showed that positive urine drug screen (UDS) for marijuana, benzodiazepines, and being a smoker (F = 3.08; P = 0.03) are significantly associated with noncompliance with buprenorphine pill count.Also, the multiple linear regression analysis of the predictable variables for noncompliance with the buprenorphine pill count showed that the psychiatric comorbidity independently (F = 4.88; P = 0.03) is significantly associated with noncompliance with buprenorphine pill count. CONCLUSIONS: Patients found to be noncompliant were more likely to suffer from comorbid psychiatric illness. Patients who tested positive for benzodiazepines or cannabis were more likely to be noncompliant with treatment. Although the rate of noncompliance (inaccurate pill count) was high, patients were still found to be taking their prescribed buprenorphine as evidenced by positive UDS for buprenorphine/norbuprenorphine. In addition, our sample had a high rate of negative UDS screens for opioids and cocaine.

The impact of buprenorphine/naloxone treatment on HIV risk behaviors among HIV-infected, opioid-dependent patients.

BACKGROUND: Opioid dependence is a major risk factor for HIV infection, however, the impact of buprenorphine/naloxone treatment on HIV risk behaviors among HIV-infected opioid-dependent patients is unknown. METHODS: We conducted a longitudinal analysis of 303 HIV-infected opioid-dependent patients initiating buprenorphine/naloxone treatment. Outcomes included self-reported past 90-day needle-sharing and non-condom use. We assessed trends over the 12 months using the Cochran-Armitage trend test. Using generalized estimating equations, after multiple imputation, we determined factors independently associated with needle-sharing and non-condom use, including time-updated variables. We then conducted a mediation analysis to determine whether substance use explained the relationship between time since treatment initiation and needle-sharing. RESULTS: Needle-sharing decreased from baseline to the fourth quarter following initiation of buprenorphine/naloxone (9% vs. 3%, p<0.001), while non-condom use did not (23% vs. 21%, p=0.10). HIV risk behaviors did not vary based on the presence of a detectable HIV-1 RNA viral load. Patients who were homeless and used heroin, cocaine/amphetamines or marijuana were more likely to report needle-sharing. Heroin use fully mediated the relationship between time since treatment initiation and needle-sharing. Women, patients who identified as being gay/lesbian/bisexual, those married or living with a partner and who reported heroin or alcohol use were more likely to report non-condom use. Older patients were less likely to report non-condom use. CONCLUSIONS: While buprenorphine/naloxone is associated with decreased needle-sharing among HIV-infected opioid-dependent patients, sexual risk behaviors persist regardless of viral load. Targeted interventions to address HIV risk behaviors among HIV-infected opioid-dependent populations receiving buprenorphine/naloxone are needed.

Stigma and its determinants among male drug dependents receiving methadone maintenance treatment.

BACKGROUND: The stigma attached to substance use is considered as a barrier to treatment, resulting in continued dependence and harmful consequences for the health of drug abusers and society. METHODS: In the current study, stigma and its relation with patient characteristics and secrecy was examined in people who were in treatment of drug dependency. Participants were 144 patients from two referral methadone treatment centers who completed a survey containing questionnaires about stigma, secrecy and other measures of drug use. RESULTS: Patients reported high levels of self-stigma and moderate levels of stigma-related rejection and perceived stigma as well as commonly using secrecy, as a way of coping. More experiencing of self -stigma was associated with unemployment, positive history of IV drug use, incarceration and heroin consumption, compared to opium use. IV drug users and unemployed persons also reported more contacts with stigma- related rejection. No association was found between stigma and previous history of treatment for substance abuse. CONCLUSION: Findings indicate stigma in individuals who are in the treatment for substance dependence and highlight the need for more studies to clarify all aspects of drug use stigma.

Perceived stress and substance use in methadone-maintained smokers.

BACKGROUND: In methadone maintenance treatment programs (MMTPs), 80-90% of participants smoke cigarettes. Patients in MMTPs are at particular risk for life stress, and nicotine, as well as other substances like alcohol, benzodiazepines, cocaine, marijuana, and opiates have been shown to reduce the effects of stress. Use of these addictive substances to cope with stress may precipitate illicit opiate relapse in MMTP patients. In the current study, we examined the relationship between perceived stress and substance abuse. METHODS: Participants were 315 cigarette smokers recruited from nine MMTPs for a smoking cessation study. Logistic regression was used to evaluate the adjusted association of perceived stress with dichotomous indicators of hazardous alcohol use and recent substance use at baseline. RESULTS: After controlling for demographic and smoking-related variables, perceived stress was associated positively and significantly with the likelihood of screening positive for hazardous drinking or alcohol-related problems (OR=1.13, 95%CI 1.02; 1.25), with the likelihood of recent cocaine use (OR=1.18, 95%CI 1.02; 1.37), and with the likelihood of recent benzodiazepine use (OR=1.24, 95%CI 1.07). CONCLUSIONS: Perceived stress may be a marker of patients' risk for illicit substance use, a known risk factor for illicit opiate relapse. These findings indicate that cigarette use might not be sufficient in managing stress and methadone-maintained persons turn to other substances for relief.

Depression in male patients on methadone maintenance therapy.

INTRODUCTION: Depression is one of the most common psychiatric conditions in men. The aim of the study was to determine the depressive symptoms and associated factors among men on methadone maintenance therapy (MMT). METHODS: A cross-sectional study was conducted involving 108 subjects who attended the Drug Clinic at Hospital Kuala Lumpur. The instruments used include the Structured Clinical Interview for Diagnostic and Statistical Manual, Fourth Edition Axis-I Disorder, Beck Depression Inventory and the 15-item International Index of Erectile Function. RESULTS: The rate of depression was 44.4%. There were significant associations between Malay ethnicity, secondary education level and concurrent illicit cannabis use with depression (P < 0.05). However, there was no significant associations between depression and erectile dysfunction (P = 0.379). DISCUSSION: Even though depression is common among men on MMT, it is often missed by the treating doctors. It is important to make the treating doctors aware that depression is a serious clinical condition that has a profound impact on the individual and compliance to treatment.
