The Royal Society for Public Health (RSPH) has called for music festivals to provide drug safety testing facilities \u2018as standard\u2019, as the summer festival season gets underway. The organisation also wants to see the harm reduction measure implemented in city nightlife areas. The call follows concerns about increasing purity levels of club drugs, with tests \u2018repeatedly\u2019 reporting ecstasy pills containing 150g and more of MDMA, compared to averages of around 50-80mg in the 1980s and \u201990s (DDN, March 2017, page 4). Drug safety testing pilots have already been carried out at UK festivals with the support of local police, and harm reduction organisation The Loop plans to extend testing to eight of this summer\u2019s events. RSPH research found that around a third of festival-goers and clubbers would \u2018definitely or probably\u2019 not take their drugs if testing revealed the strength or composition to be different than expected, while almost half said they would take less or \u2018be more careful\u2019. Last year RSPH published a report that advocated decriminalising the personal possession of all illegal drugs (DDN, July\/August 2016, page 4). \u2018While the use of stimulant club drugs such as ecstasy can never be safe, and RSPH supports ongoing efforts to prevent them entering entertainment venues, we accept that a certain level of use remains inevitable in such settings,\u2019 said RSPH chief executive Shirley Cramer. \u2018We therefore believe that a pragmatic harm reduction response is necessary.\u2019 Testing facilities provided an opportunity to \u2018impart practical harm reduction advice to an audience who would not normally engage with drug services\u2019, she continued. \u2018We urge events companies to make these facilities a standard part of the UK festival and clubbing landscape, and we urge both local and national police and public health authorities to provide the support that will enable this.\u2019 \u2018We believe that prioritising public health over criminal justice for drug users at a time of growing concern about drug-related deaths at festivals and nightclubs can help to reduce drug-related harm both on and off site,\u2019 added The Loop\u2019s director, and professor of criminology at Durham University, Fiona Measham.
