Alcohol 'more harmful than heroin' says Prof David Nutt

Alcohol is more harmful than heroin or crack when the overall dangers to the individual and society are considered, according to a study in the Lancet.
The report is co-authored by Professor David Nutt, the former government chief drugs adviser who was sacked in 2009.
It ranked 20 drugs on 16 measures of harm to users and to wider society.
Heroin, crack and crystal meth were deemed worst for individuals, with alcohol, heroin and crack cocaine worst for society, and alcohol worst overall.
The study by the Independent Scientific Committee on Drugs also said tobacco and cocaine were judged to be equally harmful, while ecstasy and LSD were among the least damaging.
Professor Nutt refused to leave the drugs debate when he was sacked from his official post by the former Labour Home Secretary, Alan Johnson.
He went on to form the Independent Scientific Committee on Drugs, which says it aims to investigate the drug issue without any political interference.
One of its other members is Dr Les King, another former government adviser who quit over Prof Nutt's treatment.
Members of the group, joined by two other experts, scored each drug for harms including mental and physical damage, addiction, crime and costs to the economy and communities.
The study involved 16 criteria, including a drug's affects on users' physical and mental health, social harms including crime, "family adversities" and environmental damage, economic costs and "international damage".
'Valid and necessary'
The findings run contrary to the government's long-established drug classification system, but the paper's authors argue that their system - based on the consensus of experts - provides an accurate assessment of harm for policy makers.
"Our findings lend support to previous work in the UK and the Netherlands, confirming that the present drug classification systems have little relation to the evidence of harm," the paper says.
"They also accord with the conclusions of previous expert reports that aggressively targeting alcohol harms is a valid and necessary public health strategy."
In 2007, Prof Nutt and colleagues undertook a limited attempt to create a harm ranking system, sparking controversy over the criteria and the findings.
The new, more complex, system ranked alcohol as three times more harmful than cocaine or tobacco. Ecstasy was ranked as causing one-eighth the harm of alcohol.
It also contradicted the Home Office's decision to make the so-called legal high mephedrone a Class B drug, saying that alcohol was five times more harmful.
The rankings have been published to coincide with a conference on drugs policy, organised by Prof Nutt's committee.
Prof Nutt told the BBC: "Overall, alcohol is the most harmful drug because it's so widely used.
"Crack cocaine is more addictive than alcohol but because alcohol is so widely used there are hundreds of thousands of people who crave alcohol every day, and those people will go to extraordinary lengths to get it."
He said it was important to separate harm to individuals and harm to society.
The Lancet paper written by Prof Nutt, Dr King and Dr Lawrence Phillips, does not examine the harm caused to users by taking more than one drug at a time.
Gavin Partington, of the Wine and Spirit Trade Association, said alcohol abuse affected "a minority" who needed "education, treatment and enforcement".
Mr Partington, who is the spokesman for the Wine and Spirit Trade Association, said millions of people enjoyed alcohol "as part of a regular and enjoyable social drink".
"Clearly alcohol misuse is a problem in the country and our real fear is that, by talking in such extreme terms, Professor Nutt and his colleagues risk switching people off from considering the real issues and the real action that is needed to tackle alcohol misuse," he said.
"We are talking about a minority. We need to focus policy around that minority, which is to do with education, treatment and enforcement."
A Home Office spokesman said: "Our priorities are clear - we want to reduce drug use, crack down on drug-related crime and disorder and help addicts come off drugs for good."
