Compared with other EU countries the drug policy of Germany is considered to be rather progressive but still stricter than, for example, in the Netherlands. In 1994 the Federal Constitutional Court ruled that drug addiction was not a crime, as was the possession of small amounts of drugs for personal use. In 2000 the German narcotic law ("BtmG") was changed to allow for supervised drug-injection rooms. In 2002, a pilot study was started in seven German cities to evaluate the effects of heroin-assisted treatment on addicts, compared to methadone-assisted treatment. The positive results of the study led to the inclusion of heroin-assisted treatment into the services of the mandatory health insurance in 2009.
