But if we'd like to look at the amazing work being done by KnowYourStuffNZ, looking at the years 2019-20, they tested 1,368 samples—according to their excellent website, which I'd like to refer you to for further information—and 86 percent were as expected, but not safe-use drugs. We're not saying that drugs are safe here. Two percent of those were cathinones: n-ethylpentylone, which can cause death and mass hospitalisations. Two percent of them were mixtures. They also found high-dose mixtures, so they had two or more doses when only one was expected, and it doesn't take a rocket scientist to work out that that's not the best plan.
