Some of these requirements include that harm-reduction advice is to be compulsory. So anybody who surrenders a substance to be tested by the drug-testing agency must get advice. That advice must be appropriate and accurate. So, for example, a drug-testing service in giving advice could not say that taking drugs is risk-free, because it never is, but they will tailor that advice to make it appropriate in the circumstances. If a person shows an indication of consuming alcohol at the same time as another substance, the advice can be: do not use this substance and take alcohol. That is about making sure that people's experience is a safe one. It's ultimately about keeping people safe and giving people good, reasonable, and accurate advice. One of the requirements is that the advice is tailored to the person and for people for whom their drug consumption appears to be problematic, it's an opportunity to engage in a conversation about that and, ideally, to refer them to appropriate services if the person is prepared to accept that their consumption is problematic.
