Drug policy and the public good: A summary of the second edition

The second edition of Drug Policy and the Public Good presents up-to-date evidence relating to the development of drug policy at local, national, and international levels. The book explores both illicit drug use and nonmedical use of prescription medications from a public health perspective. The core of the book is a critical review of the scientific evidence in five areas of drug policy: 1) primary prevention programs in schools and other settings; 2) treatment interventions and harm reduction approaches; 3) attempts to control the supply of illicit drugs, including drug interdiction and law enforcement; 4) penal approaches, decriminalization and other alternatives; and 5) control of the legal market through prescription drug regimes. It also discusses the trend toward legalization of some psychoactive substances in some countries and the need for a new approach to drug policy that is evidence-based, realistic, and coordinated. The accumulated evidence provides important information about effective and ineffective policies. Shifting the emphasis toward a public health approach should reduce the extent of illicit drug use, prevent the escalation of new epidemics, and avoid the unintended consequences arising from the marginalization of drug users through severe criminal penalties

Neurosurgical treatment for addiction:Lessons from an untold story in China and a path forward

Addiction is a major public-health crisis associated with significant disability and mortality. Although various pharmacological and behavioral treatments are currently available, the clinical efficacy of these treatments is limited. Given this situation, there is a growing interest in finding an effective neurosurgical treatment for addiction. First, we discuss the use of ablative surgery in treating addiction. We focus on the rise and fall of nucleus accumbens ablation for addiction in China. Subsequently, we review recent studies that have explored the efficacy and safety of deep-brain-stimulation treatment for addiction. We conclude that neurosurgical procedures, particularly deep-brain stimulation, have a potentially valuable role in the management of otherwise intractable addictive disorders. Larger well-controlled clinical trials, however, are needed to assess clinical efficacy and safety. We end by discussing several key issues involved in this clinical field and identifying some areas of progress

Barriers to community-based drug dependence treatment: implications for police roles, collaborations and performance indicators

ntroduction: Worldwide, people who use drugs (PWUD) are among the populations at highest risk for HIV infection. In China, PWUD are primarily sentenced to compulsory detainment centres, in which access to healthcare, including HIV treatment and prevention services, is limited or non-existent. In 2008, China's 2008 Anti-Drug Law encouraged the development and use of community-based drug dependence rehabilitation, yet there is limited evidence evaluating the efficacy and challenges of this model in China. In this study, we explore these challenges and describe how cooperation between law enforcement and health departments can meet the needs of PWUD. Methods: In 2015, we conducted semi-structured, in-depth interviews with all four staff members and 16 clients of the Ping An Centre No. 1 for community-based drug treatment, three local police officers and three officials from the local Centre for Disease Control. Interviews explored obstacles in implementing community-based drug dependence treatment and efforts to resolve these difficulties. Transcripts were coded and analyzed with qualitative data analysis software (MAXQDA 11). Results: We identified three challenges to community-based drug treatment at the Ping An Centre No. 1: (1) suboptimal coordination among parties involved, (2) a divergence in attitudes towards PWUD and harm reduction between law enforcement and health officials and (3) conflicting performance targets for police and health officials that undermine the shared goal of treatment. We also identified the take-home methadone maintenance treatment model at the Ping An Centre No. 1 as an example of an early successful collaboration between the police, the health department and PWUD. Conclusions: To overcome barriers to effective community-based drug treatment, we recommend aligning the goals of law enforcement and public health agencies towards health-based performance indicators. Furthermore, tensions between PWUD and police need to be addressed and trust between them fostered, using community-based treatment centres as mediators. The preliminary success of the take-home methadone maintenance treatment pilot can serve as an example of how collaboration with the police and other government agencies can meet the needs of PWUD and contribute to the success of community-based treatment

Use trajectories of amphetamine-type stimulants (ATS) in Shanghai, China

BACKGROUND: Although amphetamine-type stimulant (ATS) use is an important issue that has caused growing concerns in China as well as other countries, the knowledge of long-term patterns of ATS use in China is limited. This study explored long-term patterns of ATS use in Shanghai, China, and compared the differences by ATS use trajectory groups, seeking to identify risk factors that have implications for the development of targeted intervention programs. METHODS: A total of 377 ATS users were recruited from the Compulsory Isolation Center for Drug Rehabilitation in Shanghai. Group-based trajectory modeling was applied to identify distinctive trajectories of ATS use over 8 years at the time of interviews conducted in 2012. The mean number of days using ATS per month over a year from years 2005 to 2012 was analyzed with a censored normal model. RESULTS: Three distinctive groups were identified: high-use (19.1%), low-use (66.0%), and increasing-use (14.9%). Relative to the low-use group, the high-use and increasing-use groups were more likely to report having used opiate-type drugs and to have more craving experiences. Psychiatric symptoms following ATS use were frequently reported, with ATS users in the increasing-use and high-use groups more likely to report depression symptoms and suicide behaviors compared to the low-use group. The low-use and increasing-use groups reported more months in drug abuse treatment programs compared to the high-use group. CONCLUSIONS: Addressing ATS use should take into consideration patients' use-related psychiatric symptoms as well as other risk factors, particularly among those with persistent high-level ATS use trajectories
