Contributor(s): Tom Feiling | Tom Feiling analyses the thinking behind drug prohibition and how and why the strategies embarked on to date have failed so spectacularly. His critique draws on research and interviews he conducted with those with first-hand experience of cocaine and the campaign to prohibit cocaine, for his new book The Candy Machine: How Cocaine Took Over the World. He then looks at the advantages and disadvantages of the alternatives to current anti-drugs policies. Finally, he discusses how a legal, regulated market for cocaine might work in practice.
