Static testing sites provide testing services to clients at fixed locations away from events. Often these are in the entertainment districts of cities. Energy Control in Barcelona and DIMS in the Netherlands provide such services.
Off-site testing occurs away from events and away from clients. Clients submit samples by post or at drop-off locations. Those samples are analysed and then the results are publicised. Examples of this model include WEDINOS (the Welsh Emerging Drugs & Identification of Novel Substances Project) and DIMS in the Netherlands.
The UK's first trial of community-based drug safety testing was carried out in Bristol and Durham in 2018 in a church, a drugs service, and a youth and community centre. Users reported that they intended to carry out a range of harm reduction actions such as alerting friends and acquaintances, being more careful mixing substances, consuming lowered dosage, and disposing of substances.
Drug Checking Programs have been emerging across the Americas in recent years.  A directory of these programs can be found at the Harm Reduction Innovation Lab's website.
