A step towards safer drug use came about recently with the UK’s first drug-checking service at the Secret Garden Party festival. Operated by The Loop charity, the service provided hi-tech analyses of drugs submitted by festival-goers. In addition to the known toxic effects of street drugs, users are exposed to risks arising from the uncertainties of the illegal market. In the UK, for example, there are ecstasy tablets circulating that contain harmfully high doses of MDMA and other more dangerous drugs, such as PMA/PMMA.
