A study in the UK found that testing drugs at music festivals revealed that one in five substances was not as sold or acquired. One in five service users utilized the disposal service for further substances of concern in their possession and another one in six moderated their consumption. Two thirds of those whose sample was missold disposed of further substances, compared with under one in ten whose sample was as sold. Service users who acquired substances onsite at the festival were more than twice as likely to have been missold them as those acquired offsite, were nearly twice as likely to use the disposal service and were on average two years younger. Women were more likely to be using the drug for the first time and more likely to use the disposal service. Although it may be controversial, this is a cutting-edge drug safety service. The findings were published in the journal International Journal of Drug Policy.
