Alcohol is more harmful than heroin or crack, according to a study published in medical journal the Lancet. The report is co-authored by Professor David Nutt, the former UK chief drugs adviser who was sacked by the government in October 2009. It ranks 20 drugs on 16 measures of harm to users and to wider society. Tobacco and cocaine are judged to be equally harmful, while ecstasy and LSD are among the least damaging. I am sure the alcohol sellers won't like it, but his argument is interesting one; I'll add a small bit to these findings, I have not known anyone under the influence of heroin running their vehicle over someone walking at the roadside.
