Westminster has finally reached a tipping point in the drug debate and radical change is now becoming possible, Norman Baker has said. The Liberal Democrat Home Office minister was speaking to Politics.co.uk after the publication of a government report on international drug laws which found no correlation between the severity of a country's policy and levels of drug use. It is unprecedented for the Home Office to publish a report which casts doubt on its own policy for the last 40 years and many reformers are becoming increasingly confident that it could herald a sea-change in Westminster's view on the issue.
