Does Ecstasy Really Cause Brain Damage?

January 3, 2012, 12:01 am

A new study published in the Archives of General Psychiatry trumpeting the dangers of Ecstasy use received a lot of attention recently. Its findings were in direct contrast to a large study released earlier last year that reached the opposite conclusion.

To help sort this out, I lobbed a few questions at Brad Burge of the Multidisciplinary Association for Psychedelic Studies:

Q. Your group financially supports MDMA research and also hopes to get FDA approval for the drug as a prescription treatment. One of the authors of this new paper says their findings provide the “strongest evidence to date that the drug causes chronic loss of serotonin in humans.” What do you say to that?

A. In fact there is nothing new to this claim. Government-funded researchers have been making these claims ever since the media started reporting on recreational Ecstasy use in the early 1980s. Most researchers, including the authors of this study, fail to ask or answer a number of important questions: (1) Were the users they observed only taking Ecstasy, or were they taking other drugs at the same time (e.g. cocaine, alcohol, caffeine, etc.)? (2) Ecstasy is not the same as MDMA—did the drugs these women take actually contain MDMA, or contain MDMA in addition to other substances? (3) How much were they really taking? (4) Since this was an observational study, causal statements such as these should not be made.

Q. “Government-funded researchers” is a bit of a dismissive phrase. Lots of researchers are supported by funding from federal agencies. Is the implication here that, when it comes to MDMA, research financed by the government is not credible?

A. It would be more to the point to say that when it comes to MDMA, much research funded by the government has not been credible. Lots of studies, including Cowan’s [Ronald Cowan of Vanderbilt University is the study's co-author], have been methodologically flawed concerning polydrug use, unknown contents of black-market Ecstasy, and quantity of use.

Even worse, media have distorted the results to make huge, fear-based claims. There is no connection between Cowan’s study results and the associated claim that “Ecstasy causes permanent brain damage.” There are big differences between two years and forever, between changed serotonin levels and brain damage, between Ecstasy and MDMA, and between recreational and clinical use.

Studies have to be designed carefully enough that they actually measure what they claim to be measuring, and their results have to be reported responsibly.

Q. You’re certainly right that headlines overstated the case (for instance: “Ecstasy Causes Long-Term Brain Damage“). But in interviews, Cowan cautioned against assuming causation and pointed out that there’s “a difference between using the drug recreationally and using it therapeutically, at a low dose in a controlled setting.” So is this really a case of a biased study, or is it just—as you put it—irresponsible news reporting? Researchers aren’t responsible for bad headlines, right?

A. Right, as long as they carefully qualify their results and don’t leap to conclusions. Cowan’s statements and qualifications are definitely reasonable.

Irresponsible reporting of scientific results can cause real harm. Sensational headlines evoke fear, which makes it harder for people to accept research results in a rational, unbiased way.

Q. What’s the next step for MDMA research?

A. Increasingly, researchers and regulators alike are starting to take the science of MDMA at face value. Rather than ignore results or push their own agenda, a fast-growing field of researchers is studying MDMA from a clinical perspective.

We’re now in the midst of Phase 2 clinical trials of MDMA-assisted psychotherapy for posttraumatic stress disorder, and we’re showing that in the right circumstances and with the appropriate preparation MDMA can be a profoundly effective therapeutic tool. We are also offering a $10,000 grant to a team of researchers who can develop a protocol for MDMA therapy as a treatment for autism spectrum disorders.

We’re not a policy organization, we’re a research organization. We don’t lobby to change laws, but we do recognize that the research we do has a context. Part of that context is the war on drugs. When research shows, as it has, that it is possible to use MDMA, other psychedelics, and marijuana in safe and responsible ways, that undermines the logic of the war on drugs that blindly assumes that these substances can only be harmful. The fate of psychedelic research may very well depend on the quality of the public education—and journalistic coverage—that surrounds it.

    I’d pay for the hotel myself rather than stay at a faculty member house I think. Potluck dinner is fine though. I remember at one interview they sent a grad student to pick me up in her small car that contained a giant dog (great dane or something). I’m scared of dogs. I said sorry, no thanks, and took a taxi….

    Faculty guest rooms? No. The on-campus interview is a horribly stressful experience as it is. In theory, it should reproduce some of the conditions a candidate would face on the job: talking with administrators; working with senior colleagues and graduate students; interacting with undergraduates. On the real job, you get to go home and unwind in the privacy of your abode as you think about the day and prepare for the next. You don’t go to a colleague’s house and sleep over, as a rule.

    The same is true for a job search. The candidate needs to have some down time to process what has occurred. Without that down time, a candidate who is highly sought after may be disinclined to accept. It sends a signal about the way the job will be: no down time; relentless colleagues; no chance to be both an excellent teacher-scholar and *human*.

    Pot lucks are acceptable. The only risk is that a candidate may very well find herself disliking a potential colleague’s cooking. That could be awkward. That’s a risk worth taking if there is simply no money for an expensive meal or catering.

    Completely unprofessional. Forced intimacy is tacky no matter the situation.

    Regarding sending a grad student to pick up a job candidate. When I was a Masters student I was (more or less) volunteered to drop off the job candidates. Yes that’s plural. Although they had been picked up seperately, the university was interviewing the top two candidates simultaneously on campus. In fact, aside from their individual interviews with the search committee and associate dean, they were always together (though they did have seperate hotel rooms). Anyway, as they were both interviewing for a single job, needless to say the drive to the airport was more than a little awkward. Especially because one candidate was a little too opinionated (i.e. in an attempt to fill the awkward silence, as they weren’t really chatting, I turned on the radio, which was set on NPR (I thought who could object to NPR). Candidate A (who was in the front seat) announced, “I don’t listen to that garbage” and turned my radio off. What a great way to make an awkward drive even more awkward.)

    thats a great story… as I was thinking about how long it will take me to complete my degree and how it’s not soon enough.
    Bravo

    I hope to never be in school this long!

  • crhoppes

    I’m honored to work everyday with students who share Ms. Vitzhum’s persistence and commitment. On Thursday, we’ll celebrate their milestones at commencement and I’ll once again be reminded why this is really a great way to spend a career! Congratulations to all who, despite the odds, have never given up on the dream of a bachelor’s degree!

    With all due respect to Brad and MAPS work to improve the situation with certain drugs, the rat study that shows dramatic loss of serotonin in rat cortical columns did not have the issues he identifies.It’s worth taking a look at that study just to see the stain images. Anybody can see it.

     See: ME Molliver, UV Berger, LA Mamounas, DC Molliver, E O’Hearn, MA Wilson.  Neurotoxicity of MDMA and related compounds: anatomic studies.  Ann. N.Y. Acad. Sci., 600, 640-663 (1990)

    Also see: Long-lasting Effects of Recreational Drugs of Abuse on the Central Nervous SystemUna D. McCann, Kelly A. Lowe and George A. Ricaurte

    Humans are not rats, and according to reports, rats do recover after a year or so. But humans show other signs that correlate with rat work. Humans are protected from negative effects of MDMA by treatment with fluoxetine (AKA Prozac) 3 hours after initial dose of MDMA. That is also true of rats, and that suggests that humans have a similar thing happen. 

    I think that all of these drugs should become at the least decriminalized. But that does not mean that we should not engage in risk reduction education. Alcohol and cigarettes have non-positive effects too, but we accept that. 

    I should add that humans in particular have a wider range of response to psychoactive drugs than most mammals appear to. And, it is clear that many people like what happens to them with use of MDMA and its after-effects. There are quite a few psychologists who feel it was important for their careers to take MDMA so they could empathize more. What the probable finding significance is in humans is not clear.
