I thank my hon. Friend for that intervention: she is right. The challenge in many cases is that there do not seem to be significant repercussions for dealing in and manufacturing these products. Later I will touch on local examples of people who have gone round and round the judicial system, with a weak sentence for this and eight weeks for that. Not only are the drugs often more available in prison than they are on the streets, but there is no long-term repercussion for continuing to flout the laws, and people just go round and round the system.
