Dr LIZ CRAIG (Labour): Thank you, Mr Speaker. So last summer, KnowYourStuff found that only 68 percent of the samples that they tested were actually what the person expected. What they found is that that was actually much lower than in previous years. But they also found that 68 percent of the people that had the substance that turned out to be not what they thought it was then said that they wouldn't take the substance as a result.
