Ravers will be invited to take part in a study of changes to people's body temperature and activity levels in a club environment, but not told that it is aimed specifically at Ecstasy users. To correlate the findings with drug use, those taking part will be asked, without revealing their names, to answer a questionnaire about their use of drugs and to give a urine sample. The urine sample will show whether or not a person has taken Ecstasy but not how much they have taken. The aim is to build up a knowledge base for the use of workers in the field. Alex says that users soon find Ecstasy has no more good effects and go off it, but try it again later.
Most users have no grasp of the idea of tolerance to a drug.
