The Nutt-Brown-ale conjunction
Professor David Nutt seems to have followed a similar career trajectory to the late (twice) Jesus Christ. In the space of a week. He starts out honourably standing up for truth against state authority, is punished for it, and then rather immodestly showboats the whole episode.
Interviewed in The Times he tosses aside a liberal approach to drugs to demonise drink. “If alcohol was discovered tomorrow,” he says, “it would definitely be illegal.”
This is hypothetical in the extreme. Alcohol is legal precisely because it’s been manufactured into tasty drinks for a very long time and massive industries have been built around its production and distribution.
Prof Nutt appears to miss the point his own case exemplifies so sharply. That alcohol and drugs policy is based not on evidence of harm but on political and economic considerations.
This is, of course, wrong, and undermines efforts at harm reduction. But what would an evidence-based policy look like? And how are we defining harm?
Shocking figures on alcohol harm partly result from the fact that so many people drink. Here’s an amazing chart that shows what happens when you adjust for numbers of users) - scroll down to ‘Deadliest Drugs II’.
Alcohol is mid-table and, as Prof Nutt says, deadlier than ecstasy and cannabis. Yet still less than one in 10,000 drinkers die of it. I wouldn’t want to play down that one, but isn’t this a lot less than you would have thought from reading the newspapers?
The chart also shows that individual alcohol-related deaths are under-reported. But the media makes up for that in its coverage of total deaths.
Mind you, you can’t read off alcohol and drugs policy from simple evidence like this either. One of the best things I’ve read on the NuttSack affair came from the drugs agency Release (()) which explores Nutt’s much-ridiculed suggestion that horse riding is more dangerous than ecstasy.
The dangers of horse riding are clearly not reducible to the horse. For one thing the rider’s skill comes into it. And it’s the same with drink and drugs. Possessing skills and knowledge makes their use safer.
harmfulness of a drug, like its effects, does not just reside in the
molecular structure of its chemical constituents or their impact on the
body’s neurological and physiological systems,” says Release. “The
emotional and psychological frame of reference of the consumer plays an
important part, as does the social setting and its associated
expectations, myths and fantasies.
notion of a purely scientific system of drug classification is itself
something of an illusion, built on the reductive model of drug-effects
as matters of chemistry and biology. Of course, they are matters of
chemistry and biology, but they are also much, much more.”
is not an excuse to excludes scientists from making a vital contribution
to policy, but it is an argument to broaden the evidence base.
distortions around the alcohol debate can throw up some real weirdness.

The Portman Group has banned it, based on a complaint from a “member
of the public”.
The Portman Group really need any help to make daft decisions?
