My Lords, I waited until this moment to speak because it seemed unfair to comment on the amendment in the name of the noble Lord, Lord Rosser, without his having spoken to it first. I have some sympathy with what the Labour Party is proposing, but I prefer Amendments 4 and 6 proposed by the noble Baroness, Lady Meacher, for the very reason that she articulated. The market for new psychoactive substances and that for other substances covered by the Misuse of Drugs Act cannot be treated as separate. The whole reason for the existence of new psychoactive substances is the controlling of other drugs. There would be no need for people to develop so-called legal highs if they could get the high legally from controlled drugs. It is essential that the annual report includes exactly what the noble Baroness proposes: an assessment of the impact on health and the social harms brought about by the Misuse of Drugs Act and this Bill.
The noble Lord, Lord Howarth of Newport, gave a long list of things that could be included in the report. If everything he suggested was included, it might not only put the Government off producing the report but put me off reading it or trying to wade through it. I agree with the noble and learned Lord, Lord Mackay of Clashfern, that post-legislative scrutiny of a Bill such as this by a Joint Committee of both Houses would be appropriate, but it should not mean that there should not also be an annual report, because things are changing so quickly. We have heard from other noble Lords about how different drugs come into mode and out again. We therefore need an annual assessment of whether the legislation is still fit for purpose.
