Last week, the former head of the Britain's Anti-Drug Co-ordination Unit revealed he quit because he got sick of having to implement policies that he and his colleagues knew were a waste of time but which their political masters insisted publicly were the only way to tackle the drug menace.
Julian Critchley believes the world would be a better place without drugs. However, he also believes - and one would've thought this would be the starting point for anyone who's serious about tackling a major social problem - that "we must live in the world as it is, not as we want it to be".
Critchley started out against decriminalisation but soon concluded that "enforcement and supply-side interventions were largely pointless. They have no significant, lasting impact on the availability, affordability or use of drugs".
