Psychoactive Substances Bill [HL]

The impact assessment to some extent deals with that. It is plain that the difficulty has arisen in relation to the emergence of new substances whenever a particular prohibition is enacted. I hear what the noble Baroness, Lady Meacher, says about this. The problem is that by the time the enactment takes place, considerable harm may be occurring. The idea of this Bill is to prevent the production of these dangerous substances as a general matter of course.
