Prof David Nutt also told the Commons home affairs committee that he stood by his claim that horse-riding was more dangerous than taking ecstasy, despite the fact that the comparison triggered his sacking as chairman of the advisory committee on the misuse of drugs (ACMD).
Nutt told MPs the cost of policing cannabis use was only £500m a year, mainly for issuing possession warning notices, compared with the £6bn a year bill for policing the use of alcohol, including dealing with people who were drunk and disorderly.
His call for the decriminalisation of the use of all drugs was backed by a second former government drug adviser, Prof Lesley King, who told MPs that most people who took ecstasy did so without harming themselves or inflicting wider harms on society.
The two former government drug advisers were giving evidence to the Commons home affairs select committee’s inquiry into drugs policy.
Nutt defended his controversial horse-riding comparison, saying the costs to the NHS of injuries of riders who had fallen from their horses were little realised. Nor was it appreciated that riders who lost control of their horses on the roads were the cause of more than 100 serious accidents every year.
“Horse-riding is considerably more dangerous than taking ecstasy,” said Nutt. “It is a popular activity, dangerous but addictive. I am told that many riders find it difficult to give up.”
Nutt was using the example to illustrate his argument that the classification of different illegal drugs was often completely unrelated to the relative harm that their use caused society. He said politics rather than science had dominated drug policy in Britain over the 40 years since the Misuse of Drugs Act was passed in 1971. Only one drug – cannabis – had ever been downgraded and that was quickly reversed against the advice of the ACMD.
