text: The earliest reported drug checking activity began in Amsterdam in November 1970 with a group from the University Hospital of Amsterdam and samples obtained through psychiatrists working with people who used drugs.
  The earliest reported drug checking service is the Drug Information and Monitoring System (DIMS) in the Netherlands supported by the Ministry of Health, Welfare and Sport. Since 1992 the service has tested over 100,000 drug samples at a national network of twenty-three testing facilities. Service users receive results within a week via phone or email and the service publishes aggregated results describing what substances are in use.
  European countries have led the introduction of drug checking services, with Asociación Hegoak Elkartea founded in Spain in 1994, TechnoPlus in France founded in 1995, and Modus Fiesta in Belgium in 1996. DanceSafe have operated in the USA since 1998 providing reagent testing and harm reduction advice.
  More recent services include Neutravel founded in Italy in 2007, The Loop founded in the UK in 2013 and KnowYourStuffNZ in New Zealand in 2015  with Pill Testing Australia launching after a successful trial in 2018.
  In 2008, the Trans-European Drug Information network (TEDI) was created, a database compiling information from different non-profit drug checking services located in different European countries.
  On March 31, 2017, a coalition of drug safety organisations hosted the first-ever International Drug Checking Day to raise awareness of safer drug use. The initiative was aimed at recreational users, with a particular emphasis on the nightlife community, and aims to promote harm reduction—accepting that people will choose to take drugs, and providing them with tools to minimise the risks.
  In November 2021 New Zealand became the first country to make drug checking fully legal after previously allowing this under temporary legislation. Other countries like the Netherlands allow drug checking but do not have legislation to protect the clients or testers, and the practice exists in a legal grey area in countries like the US and UK.
