YOU CAN'T TRUST THE DRUG 'EXPERTS'
Research on Illicit Substances Is As Biased As Its Funding Source
"One night's ecstasy use can cause brain damage," shouted a newspaper
headline in September 2002, after the journal Science published a study
that found a single dose of the drug ecstasy injected into monkeys and
baboons caused terrible brain damage. Two of the 10 primates in the study
had even died. The media trumpeted the news around the world and drug
enforcement officials held it up as definitive proof of the vileness of
But a year later, an odd thing happened. The author of the study, George
Ricaurte, admitted his team had mistakenly injected the baboons and monkeys
with massive doses of methamphetamine, not ecstasy, and Science formally
retracted the article.
The retraction was scarcely reported and drug enforcement officials said
nothing about it. Obscure as this incident may sound, it actually
demonstrates something vitally important about research on illicit drugs,
something few laymen understand but is well known among researchers and
academics. It's a deeply politicized field, says Peter Cohen, a professor
at the Centre for Drug Research at the University of Amsterdam. "There is
no neutral science."
For critics such as Cohen, George Ricaurte illustrates the problems in
illicit drug research. Long before the Science study made him notorious,
Dr. Ricaurte was accused by some academics of producing biased science
designed to make drugs look as dangerous as possible. The motive was
funding. Scientific research and scientific careers are built on funding
and drug research is particularly expensive -- the flawed Science study
cost $1.3 million US alone.
"Researchers need to get their money from somewhere," says Cohen, but
funding options are extremely limited. Pharmaceutical companies aren't
interested. And most governments aren't prepared to pay a great deal of
money for research on drugs they have already banned. The one exception is
the United States, which lavishes money on drug research. As a result, the
U.S. National I
nstitute on Drug Abuse boasts that it "supports over 85 per
cent of the world's research on the health aspects of drug abuse and
But that money comes with ideological strings attached. The American
government is dominated by a drug-war ideology in which drugs are not
simply another health risk that can be rationally studied and regulated.
Drugs are criminal, immoral, even evil. When most people think of alcohol,
we draw a line between "use" and "abuse" -- consumption that does no harm
versus consumption that does. But because the drug-war ideology sees drugs
as inherently wicked, it erases the line between use and abuse of illicit
drugs. Any use is abuse. Any use is destructive. And the job of science is
to prove it.
In his now-retracted study, Dr. Ricaurte was trying to prove something --
that even one dose of ecstasy causes brain damage --which neatly fits
drug-war ideology. Not surprisingly, NIDA covered the $1.3 million US cost
of the research. In fact, Dr. Ricaurte has been given $10 million US by
NIDA over his career. In exchange, NIDA consistently got what it wanted:
Research that hyped the dangers of ecstasy.
But funding research is just one way American drug-war ideologues control
the scientific research on illicit drugs. Not funding research can be just
as effective when almost all the funding in the world comes from the U.S.
"If I would approach NIDA and say I want to show that marijuana use is far
less problematic than the use of alcohol, I wouldn't be funded," says Cohen.
This control can skew research in subtle but powerful ways. Cohen mentions
his own research into ordinary people whose moderate use of cocaine causes
little or no physical or social harm. He had been able to fund this work
with money from the Dutch government. "But in many other countries, my
colleagues could not find such money. They could find money to do research
on cocaine use, but only in people who are in (rehab) clinics or living on
the streets." In any other field this "selection bias" would be
unacceptable because it distorts the results. In illicit drug research,
A final method of control is crude suppression. "It goes on all the time,"
insists Cohen. "I was involved in the cocaine research of the World Health
Organization and I saw this happen."
In the early 1990s, the WHO asked a group of international scientists,
including Cohen, to produce what it billed as "the largest global study on
cocaine use ever undertaken." In 1995, the study was done. It concluded
that most users consume cocaine occasionally, that occasional use usually
does not lead to compulsive use, and that occasional use does little or no
harm to users. It was a flat contradiction of the drug-war ideology, so the
U.S. threatened to pull its funding if the report was released. The WHO
buckled. The report was buried.
Journalists are starting to catch on to the fact that they cannot always
trust what officials say about drugs, Cohen feels, but few know how
"poisoned the production of knowledge about drugs is." As a result,
misinformation abounds and "drug policy is not yet a topic that society can
deal with in a rational manner."
