Alcohol, tobacco worse than drugs

LONDON, (AP) -- New "landmark" research finds that alcohol and tobacco are more dangerous than some illegal drugs like marijuana or Ecstasy and should be classified as such in legal systems, according to a new British study.

In research published Friday in The Lancet magazine, Professor David Nutt of Britain's Bristol University and colleagues proposed a new framework for the classification of harmful substances, based on the actual risks posed to society. Their ranking listed alcohol and tobacco among the top 10 most dangerous substances.

Nutt and colleagues used three factors to determine the harm associated with any drug: the physical harm to the user, the drug's potential for addiction, and the impact on society of drug use. The researchers asked two groups of experts _ psychiatrists specializing in addiction and legal or police officials with scientific or medical expertise _ to assign scores to 20 different drugs, including heroin, cocaine, Ecstasy, amphetamines, and LSD.
