Yes, I think that is a very important point. Where the substance concerned has a psychoactive effect, it will fall under the Psychoactive Substances Act 2016, and where people are supplying it recklessly in the way that my hon. Friend the Member for Worcester just described, there is basis for action. If there is no psychoactive effect but the substance has some other adverse medical effect, that would obviously not fall within the purview of that Act, but such substances are regulated separately through the Medicines and Healthcare products Regulatory Agency and other regulators, who can make regulations to restrict supply. If there is evidence that there is misuse of substances that are legal, either tightening that regulation or having them reviewed by the Advisory Council on the Misuse of Drugs is the right way to go. If my hon. Friend has particular examples, he should write to me and I would be happy to take them up.
I am conscious that time is pressing upon us.
