I do apologise. It am not being clear. Driving under the influence of drugs, even though it has not been specified, has long been an offence, as the noble Lord is aware, and the method for enforcement has been a blood test. That has been used by all forces over many years and remains in place, so they have that capacity. However, with the new list of specified drugs, many of them are now interested in alternative screening devices, particularly mobile devices, because that puts them in a position, as it were, to issue a fixed penalty on the spot. I think we will see that take-up, given the new opportunities for enforcement that are provided by forces up and down the country. But of course they always have the fallback of using the blood test, which has always been available to them and continues to be.
I hope that I have covered the range of issues. If I have not, I will gladly read through Hansard and provide a letter with more detail. I hope, on that basis, that your Lordships will feel that they can support this order.
