I was compelled by my hon. Friend's first question and I had not thought that there was more to come. As he said, we must move away from the overuse of drugs and methadone maintenance, and aim at detoxification and returning people to a condition in which they might stay out of prison. Methadone maintenance is sometimes necessary when dealing with people who are seriously addicted when they enter prison. If people are serving a very short-term sentence, there is not much more we can do than maintain them on methadone.

However, the Ministry of Justice is looking, with my right hon. Friend the Health Secretary, to see what can be done in the context of his health reforms to deal more constructively with the huge problem of drugs offenders and crime. As I said, more than half the people whom we admit to prison are believed to have a serious drug problem when they arrive, and some who enter drug-free become addicted while there.
