So just thinking through: what does this bill do? I think basically what it does is it follows on from the previous Drug and Substance Checking Legislation Act, which is due to expire 12 months from when it came into force, and it's similar in many of the respects. But there's one main difference, and that is rather than the Director-General of Health appointing service providers under the previous Act, in this bill the director-general is able to issue licences for substance-checking services so they can carry out specified functions, and it's reasonably prescriptive what those functions are. So the first one is providing that information so that you can actually do harm minimisation and talk to those people that are potentially seeking the advice through decisions about the usage. Then the second part of it, obviously, is testing the substances and ascertaining what's in them. And then, once you've done that, having that conversation with the person that handed over the substance to say this is what's in it, and then having that responsibility to dispose of that, if that person decides to surrender their drug and also for the samples that they've tested.
