Government report: Tough laws 'do not stop drug use'

There is "no obvious" link between tough laws and levels of illegal drug use, a government report has found.

Liberal Democrat Home Office minister Norman Baker said the report, comparing the UK with other countries, should end "mindless rhetoric" on drugs policy.

But Prime Minister David Cameron said the research did not offer "specific conclusions" and that he did not "believe in" decriminalising drugs.
