Alcohol abuse is more harmful than crack or heroin abuse, according to a new study by a former British government drug advisor and other experts.
Neuropharmacologist David Nutt, MD, of Imperial College London, and colleagues rated 20 different drugs on a scale that takes into account the various harms caused by a drug. Drugs are rated on nine harms a drug causes an individual and seven harms a drug causes society.
The scale, developed by a panel of experts called the Independent Scientific Committee on Drugs (ICSD), ranges from 0 (no harm) to 100 (greatest possible harm). It is weighted so that a drug that scores 50 is half as harmful as a drug that scores 100.
"The highest and lowest overall harm scores … are 72 for alcohol and 5 for mushrooms," Nutt and colleagues calculate. "The ICSD scores lend support to the widely accepted view that alcohol is an extremely harmful drug both to users and to society."
