Ecstasy fans beware: long-term use of methylenedioxymethamphetamine (MDMA) may lead to memory loss or impairment, according to findings reported today in the journal Neurology. Over the course of a year, researchers studied 15 ecstasy users ranging in age from 17 to 31 who took the drug 2.4 times a month on average. They found that tests linked the use of ecstasy with different aspects of memory decline. The ability to recall a story after a brief delay, for example, dropped by about 50 percent between the first and second evaluations.

Konstantine Zakzanis of the University of Toronto, a co-author of the report, warns that the study relied on self-reporting by patients, which can yield misleading results. He further notes that the makeup of street drugs is variable. Still, "for those who use ecstasy repeatedly, there is preliminary evidence to suggest memory processes can be impaired with continued use of the drug," he remarks. "For those that use ecstasy once or twice in a lifetime, to date, there is no evidence suggesting impairment of memory function that is progressive or permanent in nature, although the jury of ecstasy researchers are still deliberating the matter."

She is fascinated by human origins, which she has covered for nearly 30 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home to the shores of Kenya’s Lake Turkana in search of the oldest stone tools in the world, as well as to Madagascar on an expedition to unearth ancient mammals and dinosaurs, the icy waters of Antarctica, where humpback whales feast on krill, and a “Big Day” race around the state of Connecticut to find as many bird species as possible in 24 hours. Wong is co-author, with Donald Johanson, of Lucy’s Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
