With Cocaine Vaccine, Scientists Try to Take Fun Out of Drugs

A study
reported this week in the Archives of General Psychiatry
found that an experimental "cocaine vaccine" was mostly
ineffective at reducing consumption of the drug. Less than
two-fifths of the subjects injected with the vaccine, which is
supposed to stimulate production of antibodies that bind to
cocaine molecules and prevent them from reaching the brain, had
enough of an immune system response to significantly reduce their
cocaine use (as measured by urine tests).

Even among those
subjects, only half cut back on cocaine by 50 percent or
more. "We need improved vaccines and boosters," the authors
conclude. The lead investigator, Baylor College
of Medicine psychiatrist Thomas Kosten, is nevertheless


This is the first study that has ever been done with an illicit
drug to show that a vaccine can be effective in humans. This is
establishing the principle for all drugs of abuse, whether it's
nicotine or heroin or methamphetamines. We've made vaccine for
all of those things in animals, and we can put them in humans.

Vaccine boosters think the real money lies in an
effective anti-nicotine treatment, which they believe would
attract "inveterate smokers" who have repeatedly tried to quit
with other methods. But as The New York Times notes (in
the headline, no less), such a vaccine "does not keep users
from wanting the drug." If all goes well, their cravings are
not diminished in the slightest; they just can no longer satisfy

And that's assuming the vaccine is fully effective (as
opposed to maybe 10 percent effective, like the one in the
study); if not, it could actually increase consumption
by neutralizing a percentage of each dose. A partially effective
nicotine vaccine could be hazardous to smokers' health if it
encouraged them to smoke more so as to achieve the
effect to which they're accustomed. In any case, it's not
clear how appealing the idea of biochemically taking the fun out
of smoking will be; the success of such a product hinges on
consumers looking for a way to frustrate themselves.

Still, if it helped smokers (or other drug users)
follow through on their own desire to
quit, an effective anti-drug vaccine would be a welcome
development. But I worry about the potential for
nonconsensual use of such products, in light of the fact that so
much "drug treatment" is imposed on people by the
criminal justice system and the likelihood that
mandatory vaccination of children to prevent them from ever
being tempted by psychoactive chemicals would appeal to
politicians who believe a drug-free America is just
around the corner.

The very concept of the anti-drug "vaccine,"
which portrays the drugs people voluntarily take because
they enjoy them as pathogens invading
their bodies, neatly fits with the general medicalization of
addiction, which treats choices as diseases and therefore
can easily be used
to justify a forcible "cure."

Back in 2004, I contemplated
anti-drug vaccines in Seed. More on the subject
and here.
