That is a good point. There are a number of ways. Perhaps I may make the point that I have been trying to set out the terms so that a future reader of the Official Report may actually be able to deduce—I will be careful here—what the Government intended when they set out the definition in this particular way. The noble Lord’s intervention is entirely appropriate
and I do have an answer which I will give to him, but I want to make sure that we do not lose the flow of what underlies this, which is the rationale behind the definition.
There are a number of ways, and these include data based on a human user’s experience, argument by analogy and in vitro neurochemical profiling. Working with the Centre for Applied Science and Technology at the Home Office, we will identify and build the capability in the UK to meet the demand for this new forensic requirement, as well as working with the Office of the Forensic Science Regulator to ensure that the high standard of quality that forensic evidence meets is maintained.
The Home Secretary has written to the Advisory Council on the Misuse of Drugs seeking its views on how we can strengthen the UK’s forensic capacity and capability to support the implementation of the legislation. We remain ready to consider carefully any recommendations the council may have about other aspects of the Bill. We will continue with the forensic early warning system, which has enabled forensic providers more easily to identify new psychoactive substances coming on to the UK market through the provision of reference standards and establishing a new psychoactive substances community. I am sure that that has entirely answered the noble Lord’s point.
