The UK Government's chief adviser on drugs caused fury last night by claiming booze and fags are more dangerous than LSD.
Professor David Nutt also said the risk of taking ecstasy was no worse than riding a horse - and blasted the decision to upgrade cannabis to a class B drug.
He called for all drugs to be ranked by a "harm" index - with cocaine, heroin, barbiturates and methadone the only ones more harmful than alcohol.
Tobacco would rank ninth, ahead of cannabis, LSD and ecstasy. Professor Nutt, chairman of the Advisory Council on the Misuse of Drugs, said smoking cannabis created only a "small risk" of psychotic illness.
