Switzerland implemented a harm reduction program and reduced the spread of HIV within the drug scene, and from drug users into other population groups, earlier than many countries. Each canton developed strategies based on its drug problem. By 1985 it was obvious that 'needle sharing' was the most significant pathway in the transmission of HIV. Some cities established Drug Consumption Rooms and small-scale syringe exchange programs. However, a dramatic concentration of drug use in the Platzspitz (a park) of Zürich evolved where 1000-2000 drug users gathered daily, many of whom were infected with HIV. The Federal Office of Public Health financed needle exchange and other harm reduction programs, with evaluation. Within a few years the Swiss established low-threshold methadone treatment programs and Heroin-Assisted Therapy. In 2008, the Swiss approved a law based on the principles of a 'four pillar system': repression, prevention, harm reduction, and treatment.
瑞士较早实施了减少伤害计划，在毒品场所内和在吸毒者之间减少了艾滋病毒的传播，并传播到其他人群中。每个州都根据其毒品问题制定了战略。到 1985 年，“共用针头”显然是 HIV 传播的最重要途径。一些城市建立了吸毒者娱乐室和小规模的注射器交换计划。然而，在苏黎世的普拉茨斯皮茨（一个公园）出现了毒品使用急剧集中的情况，每天有 1000-2000 名吸毒者聚集在这里，其中许多人感染了 HIV。联邦公共卫生办公室为针头交换和其他减少伤害计划提供资金，并进行评估。在短短几年内，瑞士建立了低门槛美沙酮治疗计划和海洛因辅助治疗。2008 年，瑞士根据“四大支柱系统”的原则批准了一项法律：镇压、预防、减少伤害和治疗。
