Use of drugs at 'raves'.

Widespread use of drugs at the currently popular 'raves' has caused concern principally because of an increasing number of cases of serious toxicity and even death. The availability and use of drugs at raves, mainly in the Edinburgh area, have been investigated and self-reported use of drugs compared with results of urine screening. Use of Ecstasy and LSD have been confirmed and there is evidence to support the use of Khat. A new preparation, Herbal Ecstasy, is readily available at Edinburgh raves and appears to be widely used. All urines tested positive for one or more drugs or drug metabolites and in general analytical results correlated well with self-reported use of drugs.
