Just looking at the New Zealand Drug Foundation website, it describes what actually happens if you do go to a festival and turn up to have your drugs or substances tested. What it says is you will receive a one-on-one service, and it takes about 15 minutes. So what will happen is trained volunteers will take a very small sample of your substance, and they'll divide it into three piles. Two of those piles are tested with reagents, and what that does is it's got acids and it makes colour changes if certain substances are present. Then one of the piles is tested with a spectrometer and what it does is it compares your sample against other known samples of known substances and it can detect the presence of unexpected substances, adulterants, or additives. Then what you get in that 15 minutes is you get a report, and you also get some harm reduction advice. As I was mentioning in my previous contribution, about 20 percent of people's substances don't turn out to be what they thought they were and another 11 percent have got additives that were completely unexpected. So then it's your choice whether you go ahead and you take that substance or not. In many cases, if there's a difference in what you're expecting, you don't take the substance—harm reduction and issue averted.
