Letter from the Director
The so-called "club drug" MDMA continues to be used by millions of Americans across the country, despite evidence of its potential harmful effects. 3,4-methylenedioxymethamphetamine (MDMA, or ecstasy) has gained a deceptive reputation as a "safe" drug among its users. This illegal drug, which has both stimulant and psychedelic properties, is often taken for the feelings of well-being, stimulation, and the distortions in time and sensory perceptions that it produces. MDMA first became popular in the "rave" and all-night party scene, but its use has now spread to a wide range of settings and demographic subgroups. According to the 2004 National Survey on Drug Use and Health, more than 11 million people have tried MDMA at least once.
Myths abound about both the acute effects and long-term consequences of this drug, often called ecstasy or "X". Indeed, one reason for the rapid rise in the drug’s popularity is that many young people believe that MDMA is a new safe drug. But MDMA is not new to the scientific community, as many laboratories began investigating this drug in the 1980s, and the picture emerging from their efforts is of a drug that is far from benign. For example, MDMA can cause a dangerous increase in body temperature that can lead to kidney failure. MDMA can also increase heart rate, blood pressure, and heart wall stress. Animal studies show that MDMA can damage specific neurons in the brain. In humans, the research is not conclusive at this time; however, a number of studies show that long-term, heavy MDMA users suffer cognitive deficits, including problems with memory.
NIDA-supported research is developing a clearer picture of the potential dangers of MDMA, and this Research Report summarizes the latest findings. We hope that this compilation of scientific information will inform readers and help the public recognize the risks of MDMA use.

This series of reports simplifies the science of research findings for the educated lay public, legislators, educational groups, and practitioners. The series reports on research findings of national interest.
As a result of scientific research, we know that addiction is a disease that affects both brain and behavior.
