Alcohol ranks “most harmful” among a list of 20 drugs — beating out crack and heroin — according to study results released by a British medical journal.
A panel of experts weighed the physical, psychological and social problems caused by the drugs and determined that alcohol was the most harmful overall, according to an article on the study released by The Lancet Sunday.
Using a new scale to evaluate harms to individual users and others, alcohol received a score of 72 on a scale of 1 to 100, the study says.
That makes it almost three times as harmful as cocaine or tobacco, according to the article, which is slated to be published on The Lancet’s website Monday and in an upcoming print edition of the journal.
Heroin, crack cocaine and methamphetamine were the most harmful drugs to individuals, the study says, while alcohol, heroin and crack cocaine were the most harmful to others.
In the article, the panelists said their findings show that Britain’s three-tiered drug classification system, which places drugs into different categories that determine criminal penalties for possession and dealing, has “little relation to the evidence of harm.”
Panelists also noted that the rankings confirm other studies that say that “aggressively targeting alcohol harms is a valid and necessary public health strategy.”
