Relapse to Opioid Use in Opioid-Dependent Individuals Released from Compulsory Drug Detention Centres Compared with Those from Voluntary Methadone Treatment Centres in Malaysia: A Two-Arm, Prospective Observational Study

Abstract
Detention of people who use drugs into compulsory drug detention centres (CDDCs) is common throughout East and Southeast Asia. Evidence-based pharmacological therapies for treating substance use disorders, such as opioid agonist treatments with methadone, are generally unavailable in these settings. We used a unique opportunity where CDDCs coexisted with voluntary drug treatment centres (VTCs) providing methadone in Malaysia to compare the timing and occurrence of opioid relapse (measured using urine drug testing) in individuals transitioning from CDDCs versus methadone maintenance in VTCs. Opioid-dependent individuals in CDDCs are significantly more likely to relapse to opioid use after release, and sooner, than those treated with evidence-based treatments such as methadone, suggesting that CDDCs have no role in the treatment of opioid-use disorders.

    Making Drug Treatment Work
    (World Bank, Washington, DC, 2018) Wegman, Martin P.; Altice, Frederick L.; Kaur, Sangeeth; Rajandaran, Vanesa; Osornprasop, Sutayut; Wilson, David; Wilson, David P.; Kamarulzaman, Adeeba
    Compulsory drug detention centers (CDDCs) are common throughout Asia. However, medical treatments for substance use disorders, such as opioid agonist treatment (OAT), are generally unavailable in these settings. In this report, the authors compare the effectiveness of CDDCs with voluntary drug treatment centers (VTCs) offering OAT in Malaysia. Positive urine drug testing (UDT) after release confirmed opioid relapse in both groups. Specifically, the authors measure the timing of relapse, that is, the authors compare when patients that have been discharged from CDDCs and VTCs relapse to opioid. The authors conducted a study on opioid dependent individuals from Malaysian CDDCs and VTCs from August 2012 to September 2014. Baseline (at the starting point of the study) and semi-monthly behavioral assessments and UDTs were conducted for up to one year after release and discharge. Relapse rates between the groups were compared using advanced statistical analysis. Screening occurred in 168 CDDC attendees and 113 VTC in-patients, with 89 (CDDC), and 95 (VTC) of these individuals, respectively, having a baseline interview and at least one UDT. The authors found that opioid-dependent persons that have been released from CDDCs relapse to opioid use significantly faster than those from VTC services. This suggests the services provided by CDDCs have little role in the treatment of opioid use disorders.

    Return on Investment and Cost-Effectiveness of Harm Reduction Program in Malaysia
    (Washington, DC, 2014-01) Naning, Herlianna; Kerr, Cliff; Kamarulzaman, Adeeba; Osornprasop, Sutayut; Dahlui, Maznah; Ng, Chiu-Wan; Wilson, David P.
    Cases of human immunodeficiency virus (HIV) infections were first detected in Malaysia in 1986. Since then, the number of new HIV cases has been increasing steadily to a peak of 6,978 new cases detected in 2002 then declining to 3,438 new cases in 2012. In response to the escalating epidemic, the Government of Malaysia (GOM) agreed the implementation of needle syringe program (NSP) and methadone maintenance therapy (MMT) programs against much public opposition which viewed these programs as being against the Islamic religion and will encourage more people to use drugs. The main objectives of this study are to evaluate whether the harm reduction program in Malaysia is cost-effective and also whether they provide return on investments (ROIs) to the government. The study used an epidemiologic mathematical model of HIV transmission and disease progression, called the projection and evaluation tool (Prevtool) developed by a team of investigators at the Kirby Institute, University of New South Wales, Australia to simulate the impact of MMT and NSP on the transmission of HIV among people who inject drugs (PWIDs) in Malaysia. Briefly, the model simulates the number of PWID who become infected with HIV over time as well as the extent of disease progression among those infected in the presence and absence of harm reduction program in the country. This study has shown that the combined MMT and NSP programs as implemented in Malaysia are cost-effective and are expected to produce net cost-savings to the government in the future. Evidence of cost-effectiveness and expected cost-savings support policy recommendation that both MMT and NSP programs should be maintained as part of the key strategy to control HIV spread among PWIDs in Malaysia. Study findings that even with the present program coverage, harm reduction activities are expected to become more cost-effective and cost-saving in the future suggest that policies towards program expansion may demonstrate higher value for money.

    Scaling up HIV Treatment for MSM in Bangkok
    (World Bank, Washington, DC, 2015-05-01) Zhang, Lei; Phanuphak, Nittaya; Henderson, Klara; Nonenoy, Siriporn; Srikaew, Sasiwan; Shattock, Andrew J.; Kerr, Cliff C.; Omune, Brenda; van Griensven, Frits; Osornprasop, Sutayut; Oelrichs, Robert; Ananworanich, Jintanat; Wilson, David P.
    The HIV epidemic amongst men who have sex with men (MSM) in Bangkok is substantial. The population size of MSM in Bangkok is 120,000-250,000, with approximately one-third (33.5 percent) considered high-risk, characterized by their young age, multiple partnerships, frequent unprotected anal intercourse, and sexual activities around MSM hotspots. In metropolitan Bangkok, HIV prevalence among MSM reportedly increased from 21 percent to 28 percent between 2000 and 2012. The Thai Working Group of Estimation and Projection (2013) projected an estimate of 39,000 new HIV infections would occur in Thailand during 2012-2016, based on the AIDS Epidemic Model (AEM). MSM will account for 44 percent of these new HIV cases, and 25-30 percent of these infections will likely to occur in Bangkok. In 2011, the United Nations held a high-level meeting on HIV/AIDS where they adopted the ambitious epidemiological targets of the United Nations Political Declaration on HIV/AIDS (UNPD), to be met by 2015. Attaining these specific targets would lead to substantial progress towards ending AIDS. UNAIDS has also been prioritizing the “Getting to Zero” initiative (“Zero new HIV infections. Zero AIDS-related deaths. Zero discrimination.”). The Bangkok Metropolitan Administration (BMA) recently responded with the “Bangkok: Getting to Zero” initiative, which strategizes an increased focus on prevention amongst MSM in the city. The clinical trial, HPTN052, demonstrated a 96 percent reduction of HIV transmission among heterosexual discordant couples who received ART. “Treatment as prevention” has become an increasingly accepted strategy to prevent new infections. A cost-effectiveness analysis comparing current levels of investment in targeted HIV prevention interventions for MSM in Bangkok (including treatment), with scenarios of increased coverage, would provide evidence to shape efficient national and metropolitan strategies. A return-on-investment analysis would provide an economic rationale to finance this strategy in allocating sufficient resources to address the epidemic at the most appropriate scale. Demonstration by the study that a significant reduction in transmission (including potential elimination) are both feasible and cost effective, may galvanize global political support.

    The Drug Treatment Court Concept : The Jamaican Drug Courts
    (World Bank, Washington, DC, 2013-01) Haisley, Stephane Jackson
    The Drug Treatment Court (DTC) model was conceived out of the need to solve the numerous and intractable problems that drug related cases create for court systems. A DTC is generally seen as a court that deals specifically with offenders who have committed offenses while under the influence of drugs and provides an alternative to incarceration. DTCs make use of a multidisciplinary team involving judges, prosecutors, defense attorneys, probation officers, treatment providers, police officers, and educational and vocational experts. The criminal justice and health service systems join to provide drug-dependent offenders with the mechanisms to recover from drug addiction and lead a productive and crime-free life. The purpose of this paper is to explore the concept of DTCs. After providing an overview of the origins of the DTC, looking at its roots in the United States and Canada, the paper examines the foundation and present-day experiences of DTCs in Jamaica. It also refers to some efforts among various countries in the Western Hemisphere to monitor DTCs and evaluate their effectiveness. The paper concludes with a return to the achievements of DTCs in Jamaica and a brief look at the future of the DTC program worldwide.

    Harm Reduction Policies and Interventions for Injection Drug Users in Thailand
    (World Bank, Washington, DC, 2011-08) Tyndall, Mark
    The World Bank initiated a review of HIV prevention among injection drug users in Thailand, with the objective of providing technical assistance to strengthen national capacity to develop state-of-the-art injecting drug use harm reduction interventions. Thailand has received international recognition for its successful interventions to reduce the transmission of HIV among female sex workers and military recruits. It is looked upon as a role model for HIV education and awareness campaigns that include the extensive promotion and wide acceptance of condoms as an HIV prevention strategy. Thailand has the most progressive and comprehensive antiretroviral program in the region with a reported coverage of over 80 percent of eligible individuals. In 2001, it embarked on a progressive universal health care program that provides free access to a wide array of health care diagnostics and therapeutics for the people of Thailand. With these impressive achievements, it is remarkable how poorly Thailand has responded to the HIV epidemic among injection drug users (IDUs). From available data, it appears that the HIV prevalence rates among IDUs have remained high and stagnant over the last decade. Failure to provide effective interventions to reduce HIV transmission among drug users has resulted in unnecessary suffering, and for many, HIV-related death. Continued inaction threatens to undermine successful HIV prevention efforts in the country through ongoing HIV transmission among injection drug users and their sexual partners. The current focus on enforcement and punishment, along with the reliance on compulsory drug treatment centers, has done little to control drug use in Thailand. The unintended consequence of this approach has been to push drug users into precarious and dangerous environments that have directly led to risky drug using patterns and persistently high rates of HIV transmission. Adopting a harm reduction approach to deal with injection drug use could have a major impact on reducing HIV transmission as well as engaging drug users into better health care and effective drug treatment. This will require strong leadership in key government Ministries and related agencies so that the central stakeholders can roll out harm reduction programs. Thailand has the potential to greatly reduce the transmission of HIV among injection drug users and become a regional leader in harm reduction.

    Housing Subsidies for Refugees
    (Washington, DC: World Bank, 2025-01-22) Tamim, Abdulrazzak; Smith, Emma; Palmer, I. Bailey; Miguel, Edward; Leone, Samuel; Rozo, Sandra V.; Stillman, Sarah
    Refugees require assistance for basic needs like housing but local host communities may feel excluded from that assistance, potentially affecting community relations. This study experimentally evaluates the effect of a housing assistance program for Syrian refugees in Jordan on both the recipients and their neighbors. The program offered full rental subsidies and landlord incentives for housing improvements, but saw only moderate uptake, in part due to landlord reluctance. The program improved short-run housing quality and lowered housing expenditures, but did not yield sustained economic benefits, partly due to redistribution of aid. The program unexpectedly led to a deterioration in child socio-emotional well-being, and also strained relations between Jordanian neighbors and refugees. In all, housing subsidies had limited measurable benefits for refugee well-being while worsening social cohesion, highlighting the possible need for alternative forms of aid.

    Ukraine Country Environmental Analysis
    (World Bank, Washington, DC, 2016-01) World Bank
    The objective of the Country Environmental Analysis (CEA) is to assess the adequacy and performance of the policy, legal, and institutional framework for environmental management in Ukraine, in light of the decentralization process of environmental governance and wider reform objectives, and to provide recommendations to government to address the key gaps identified. Ukraine is the second largest country in Europe and has a population of 43 million, the majority of whom live in urban areas. It is a lower middle income country, with the services, industry and agriculture sectors being main contributors to the country’s Gross Domestic Product (GDP). Ukraine faces a number of environmental challenges, as identified in its National Environmental Strategy 2020 (NES). Key among these are: air pollution; quality of water resources and land degradation; solid waste management; biodiversity loss; human health issues associated with environmental risk factors; in addition to climate change. The scope of Ukrainian environmental legislation is quite broad and comprehensive (more than 300 legal acts) and covers most areas of environmental protection and natural resources management. However, the environmental legislation faces a number of weaknesses:The environmental legislation is largely declaratory in nature and does not have all the essential enforcement mechanisms for the implementation of legal acts and international agreements; Many of the acts are not coordinated with each other; and Legislation undergoes limited analysis of its impact—for example, no in-depth analysis such as Regulatory Impact Analysis is conducted for proposed pieces of legislation.

    Digital Africa
    (Washington, DC: World Bank, 2023-03-13) Begazo, Tania; Dutz, Mark Andrew; Blimpo, Moussa
    All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.

    Thailand Monthly Economic Monitor, October 2025
    (Washington, DC: World Bank, 2025-10-22) World Bank
    Fiscal conditions remained stable, with a modest widening of the deficit to 3.1 percent of GDP. New stimulus measures are expected to support short-term demand without breaching the public debt ceiling. Inflation stayed negative, reflecting lower energy and food prices amid subdued domestic demand. The central bank kept the policy rate unchanged, citing limited policy space. Thailand’s growth momentum has slowed further as manufacturing activity and services weakened as projected. Tourism remained subdued, largely due to fewer Chinese visitors. Goods exports also slowed as earlier front-loaded orders faded, particularly in agriculture and industrial goods. The Thai baht depreciated in early October as the US dollar appreciated and the current account turned negative.
