When it came to testing ketamine, the test turned a lighter colour, making it less likely ketamine could be masked. Mr Andrews said generally the drug testing services worked with a spectrometer, yielding a more reliable result, but it was unavailable for O-Week. About 60 drug tests had been carried out, but the testers interacted with more than 60 people, as some arrived in groups, Mr Boyle said. The number was low when set against the number of illicit drug users believed to be present. However, the results were consistent with all the other drug testing Know Your Stuff and the Drug Foundation had carried out at festivals this year.
