Crime and Courts Act 2013 (Consequential Amendments) (No. 2) Order 2015

My Lords, I have come very recently to this debate, but I was interested to come along and listen to it. I am interested in two areas, which are probably old territory—I hope that the Minister will forgive me. This is an important bit of legislation; drug-driving is equally as dangerous and as much of a hazard to fellow citizens as drink-driving. However, I am still unclear how the enforcement of this testing is to be done in a practical way. We always think of drug-driving as being about illegal drugs, but presumably some legal highs or even medicinal pharmaceuticals, particularly tranquilisers, can be equally dangerous. Is that covered in this legislation? I would be interested to hear and understand that context.
