The world drug problem and sustainable development With 2016 marking the first year of the adoption of the new Sustainable Development Goals (SDGs), the report provides a special focus on the world drug problem within this context. In analysing these linkages the SDGs have been divided in five broad areas: social development; economic development; environmental sustainability; peaceful, just and inclusive societies; and partnerships. The report highlights a strong link between poverty and several aspects of the drug problem. Indeed, the brunt of the drug use problem is borne by people who are poor in relation to the societies in which they live, as can be seen in stark terms in wealthier countries. The strong association between social and economic disadvantage and drug use disorders can be seen when analysing different aspects of marginalization and social exclusion, such as unemployment and low levels of education.The report also sheds some light on the varied ways in which the world drug problem results in different manifestations of violence. While the intensity of drug-related violence is greatest when associated with drug trafficking and production, these do not necessarily produce violence, as illustrated by the low levels of homicide in transit countries affected by the opiate trafficking routes in Asia. The drug trade is generally seen to flourish where State presence is weak, where the rule of law is unevenly applied, and where opportunities for corruption exist.The report analyses the influence of the criminal justice system on drug trafficking and drug markets, as well as on drug use and people who use drugs. For example, it notes that globally 30 per cent of the prison population is made up of un-sentenced or pre-trial prisoners. Among the convicted prisoners, 18 per cent are in prison for drug-related offences. The excessive use of imprisonment for drug-related offences of a minor nature is ineffective in reducing recidivism and overburdens criminal justice systems, preventing them from efficiently coping with more serious crimes. Provision of evidence-based treatment and care services to drug-using offenders, as an alternative to incarceration, has been shown to substantially increase recovery and reduce recidivism.
