11. Harm reduction interventions aim to reduce the harms associated with the use of psychoactive drugs, without necessarily discouraging use. They include needle and syringe programmes, prescription of substitute medications, drug-consumption rooms, promotion of non-injecting routes for the administration of drugs, overdose prevention practices, and outreach and education programmes (see A/65/255, para. 50). Persons who inject drugs are at a heightened risk of contracting HIV, hepatitis B and C,6 and tuberculosis.7
12. The Committee on Economic, Social and Cultural Rights,8 the Committee on the Rights of the Child9 and the Special Rapporteur on the right to health have all determined that a harm reduction approach is essential for persons who use drugs. WHO, UNODC and the Joint United Nations Programme on HIV/AIDS (UNAIDS) promote harm reduction for injecting drug users.10 The Office of the United Nations High Commissioner for Human Rights has supported harm reduction and the Human Rights Council, in its resolution 12/27, recognized the need for harm reduction programmes.
13. Needle and syringe programmes involve the provision of sterile injection equipment to injecting drug users. WHO has endorsed the use of such programmes, noting that they reduce HIV infections substantially, in a cost-effective manner, without any major negative consequences.11 Needle and syringe programmes eliminate contaminated needles, which reduces the risk of transmitting HIV and other blood-borne diseases such as viral hepatitis, in particular hepatitis B and hepatitis C (see A/65/255, para. 51).12
14. Opioid substitution therapy13 is an evidence-based approach involving the prescription of medications such as methadone or buprenorphine to treat opioid dependence. Opioid substitution therapy decreases the prevalence of injecting drug use and of sharing injecting equipment, thereby reducing the risk of contracting HIV and other blood-borne viruses, and is effective in managing withdrawal from opioids and preventing a relapse into drug use (see A/65/255, para. 52). WHO has recommended that all people from key populations who are dependent on opioids be offered and be given access to opioid substitution therapy.14
15. Drug overdoses, most of which involve opioids, are the main cause of drug-related deaths. Opioid substitution therapy reduces the use of drugs by injection and thus of overdosing by almost 90 per cent.15 The Special Rapporteur on the right to health and WHO have highlighted that first aid training for the administration of naloxone, which counters the effects of opioid overdose, can prevent overdose-related deaths and minimize the harm associated with drug overdose (see A/65/255, para. 54).16
16. Providing drug users with access to drug-consumption rooms can contribute to preventing the transmission of diseases and to reducing damage to the veins, as well as encourage users to make use of treatment and other services. Drug-consumption rooms have contributed to reducing overdose rates and increased access to medical and social services (see A/65/255, para. 54).
17. As of 2014, needle and syringe programmes had been implemented in 90 countries and opioid substitution therapy was available in 80 countries.However, needle and syringe programmes have been confirmed to be absent in 68 countries where drugs are injected.In 2014, it was reported that there were 88 drug-consumption rooms worldwide, of which only two were outside of Europe, Australia and Canada.17
18. The lack of needle and syringe programmes, in particular, has a direct impact on the spread of HIV. People who inject drugs account for approximately 10 per cent of all new HIV infections and for up to 30 per cent of new HIV infections outside sub-Saharan Africa. Worldwide, an estimated 12.19 million people inject drugs, of whom 1.65 million are living with HIV.18 WHO has estimated, on the basis of data from 49 countries, that the average risk of HIV infection is 22 times greater among people who inject drugs than among people in the general population; in 11 of those countries, the risk is at least 50 times higher.19
19. Among the benefits associated with harm reduction programmes is the increased entry into HIV/AIDS treatment programmes (see A/65/255, para. 57). UNODC, WHO and UNAIDS have recommended that a comprehensive package of harm reduction services be integrated into national AIDS programmes, both as an HIV prevention measure and to support adherence to antiretroviral therapy services and medical follow-up for people who use drugs.20
20. One study compared countries that comprehensively and consistently adopted approaches based on harm reduction without punitive approaches with countries that steadfastly resisted the harm reduction programmes and focused instead on punitive approaches. It found that the prevalence of HIV among people who injected drugs in Australia, Germany, Switzerland and the United Kingdom of Great Britain and Northern Ireland was less than 5 per cent, whereas in the Russian Federation and Thailand HIV prevalence among people who injected drugs was over 35 per cent.21
