Think harder about ecstasyAdvocates of therapeutic uses of the drug ecstasy have won the right to research its performance, but opponents continueto snipe. Both sides need to look more deeply into their research agendas.

In a series of studies beginning this year, doctors will give patientswith mental problems a drug to try to ease their trauma. Butunlike most other drugs tested in clinical trials today, this experi-

mental treatment, MDMA, or ecstasy, is also widely used in clubsaround the world. Proponents of the MDMA trials say that they are long overdue, and have been stalled by political concerns (seepage 126). Opponents of the trials say that the trials’ organizers areplaying with fire by introducing potentially toxic substances intoperhaps unstable people. So who is right?

The truth is that there is a shortage of scientific logic on both sides of the MDMA debate. Those who demonize the drug are so convinced of its deadly nature that, when Johns Hopkins researcherGeorge Ricaurte reported that even a single dose of MDMA causesdebilitating, Parkinson’s-like disease in monkeys (G. Ricaurte et al.Science 297, 2260–2263; 2002), the paper was widely touted as proof that MDMA was fatally toxic. Nobody had reported similarfindings before, but this mattered little; anti-drug activists had theproof they had long been seeking that MDMA was much worse thanjust a harmless party drug.

But it later emerged that the findings were fatally flawed becausethe MDMA had been mixed up with methamphetamine — a drug ofabuse already known to be potentially fatal. The available evidenceshows that MDMA can cause psychosis, hyperthermia and evendeath in some people who take the drug recreationally. But there is no research to indicate whether or not this will be a problem in thecontrolled settings of a clinical trial, or whether such controlledadministration might result in long-term brain damage.

On the other side of the debate, MDMA’s supporters claim thatthe drug is a potentially valuable therapeutic aid with little risk ofcausing lasting brain damage. They argue that studies showing thatMDMA leads to cognitive deficiencies are procedurally flawed, andthat there is no proof that a few doses of the drug will cause harm.They point to anecdotal reports of the drug’s benefits to show that it should be evaluated as a possible aid to psychotherapy for debili-tating conditions such as post-traumatic stress disorder. But norigorously controlled trials have suggested that MDMA has long-term curative properties,and the drug’s effects on people with seriousmental disturbances have not been evaluated. The drug has also been reported in conjunction with at least 12 cases of psychosis in the medical literature.

Of course, much scientific research is driven by non-scientific motivations, and no drug would ever be proven to work in clinical trials without an interested champion. But in this case, both sides in the debate would benefit by taking a step back and re-focusing their work.

MDMA’s detractors in particular would be wise to study the moreimmediate and realistic side effects of the drug, such as its inter-actions with other drugs of abuse, and the processes whereby it cansometimes lead to life-threatening hyperthermia. This more reflec-tive approach would help researchers learn more about the origins ofand responses to the frightening side effects that sometimes occurwhen users take MDMA as a recreational drug. This would surely be a better way of ensuring that safe treatments reach the patients who need them. ■

After a decade of democratic government in South Africa, theface of research remains largely untransformed. Publishedresearch has declined significantly in relation to global out-

Very few able school-leavers are being attracted into research careers and,despite the de-segregation of the country’s school system, only atiny proportion of black scholars leave school with university-entrance qualifications in mathematics and physical science.
