hello there, chemist here....thank you for sharing your opinions. mine are delineated by asterisks, below. all the best, chemist

> There's nothing "safe", "useful", or "positive" about ecstasy as the chemist suggests.

*** is this your opinion, or is this a factual statement? further, you refer to ecstacy, and hence by using the ``street'' name, i conclude you are referring to the illicitly and often contaminated substance sold as pure 3,4-methylenedioxymethamphetamine: am i correct? ***
>
> I don't know the chemistry but ecstasy uses up something in the brain having to do with the capacity to feel pleasure.

*** the above statement does not lend credence to your opening salvo: you deny knowledge of the chemistry involved and implicate depletion of a substance you are unable to name. ***

"Holes" in the brain are readily visible in those who've taken even a few doses.

*** are you sure? please do point me in the direction of the source(s) of this claim. thanks in advance. ***

*** again, please provide some references. i am obviously very interested in this topic - as are you - and i look forward to adding your supporting materials to my files. ***

The two factors which must be present, for brain damage to occur, are either or both of, a very high single dose, and repeated dosing without a recovery period between doses.

The first abstract below demonstrates this relationship nicely. Note that the threshold for brain damage, or even abnormal brain chemistry post-use, is greater than 4 mg/kg (by interperitoneal injection, not oral), a dose three times the typical human dose, employing a route of intake not normally employed by humans. Only repeated use, far in excess of that frequency used by any but the most committed clubbers, caused measurable changes in brain chemistry. The authors conclude, "We suggest that damage occurs when endogenous free radical scavenging mechanisms become overwhelmed or exhausted." In other words, antioxidant levels can be used up, if you overdo it. That's what leads to the damage, not the acute drug effects.

The second one makes two very clear points. Prior to its publication, only two studies had shown neurological damage from MDMA, and only following *very high doses*, not specified in the abstract.

By no means am I saying that makes MDMA safe, but dose (and frequency of dose) make the poison. The post-MDMA depletion of serotonin is not permanent. Your body will make as much as it needs, within no more than 48 hours.

The relationship between the degree of neurodegeneration of rat brain 5-HT nerve terminals and the dose and frequency of administration of MDMA ('ecstasy').

O'Shea E, Granados R, Esteban B, Colado MI, Green AR.

Departamento de farmacologia, Facultad de Medicina, Universidad Complutense, Madrid, Spain.

The effect of varying the dose and frequency of administration of 3,4-methylenedioxymethamphetamine (MDMA or 'ecstasy') on both the acute hyperthermic response and the long term neurodegeneration of 5-hydroxytryptamine (5-HT) nerve terminals in the brain has been studied in Dark Agouti rats. A single injection (4-15 mg/kg i.p.) of MDMA produced immediate dose-related hyperthermia and a dose-related decrease in 5-HT, 5-hydroxyindoleacetic acid (5-HIAA) and [3H]paroxetine binding in regions of the brain 7 days later, with a dose of 4 mg/kg having no degenerative effect. This dose was also without effect when given once daily for 4 days, but produced a marked loss of [3H]paroxetine binding and indole concentration ( approximately 55%) when given twice daily for 4 days. When a dose of 4 mg/kg was given twice weekly for 8 weeks it had no effect on these serotoninergic markers, despite a clear anorectic effect of the drug being seen. These data demonstrate that MDMA-induced neurodegeneration is related to both the dose and frequency of administration and indicate that damage to 5-HT neurones can occur in the absence of a hyperthermic response to the drug. We suggest that damage occurs when endogenous free radical scavenging mechanisms become overwhelmed or exhausted.

Demonstration and localization of neuronal degeneration in the rat forebrain following a single exposure to MDMA.

Schmued LC.

Department of Neurotoxicology, National Center for Toxicological Research/FDA, Jefferson, AR 72079, USA. lschmued@nctr.fda.gov

Methylenedioxymethamphetamine (MDMA, Ecstasy) is a powerful releaser of serotonin. Increasing recreational use of this stimulant and hallucinogenic drug has raised concerns about its potential to produce brain damage. The vast majority of previous research studies have focused on the compound's ability to deplete serotonin (5-hydroxytryptamine, 5-HT) from axon terminals. Despite extensive research on this '5-HT terminal neurotoxicity', a much less studied aspect of MDMA toxicity involves its ability to actually kill nerve cells. Only two prior studies mention the existence of MDMA-induced neuronal degeneration, as reflected by a limited number of argyrophylic neurons within the somatosensory cortex, following very high doses of MDMA. The development of Fluoro-Jade B as a simple and reliable marker of neuronal degeneration has allowed us to conduct the first comprehensive localization of MDMA induced neuronal degeneration throughout the entire rat forebrain. In addition to the previously reported neuronal degeneration within parietal cortex, degenerating neurons were also observed in the insular/perirhinal cortex, the ventromedial/ventrolateral thalamus, and the tenia tecta. The extent of neuronal degeneration observed generally correlated with the degree of hyperthermia achieved.

> There is an implication that used correctly, MDMA possibly is safe, according to your post. I believe this is not the case and feel it is reckless to imply this.

Well, your position probably arises from a much-publicized paper in the prestigious journal Science, which was later subject to a much less-publicized full retraction. The study had used the wrong drug! The primates had received no MDMA at all! See the first abstract, along with a link I've added, which gives the full-text of the retraction.

Also, that prestigious researcher, Ricaurte, later gave MDMA to monkeys for eighteen months, as much as they wanted. Following two months of withdrawal, there was no change in brain neurotransmitter levels from normal levels. "Further, there were no measurable decrements in serotonin (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), dopamine (DA), 3,4-dihydroxyphenylacetic acid (DOPAC) or VMAT in any brain regions assayed."

There goes another myth.

Severe dopaminergic neurotoxicity in primates after a common recreational dose regimen of MDMA ("ecstasy").

Ricaurte GA, Yuan J, Hatzidimitriou G, Cord BJ, McCann UD.

Department of Neurology, Johns Hopkins Bayview Medical Center, Johns Hopkins University School of Medicine, Baltimore, MD 21224, USA. Ricaurte@jhmi.edu

The prevailing view is that the popular recreational drug (+/-)3,4-methylenedioxymethamphetamine (MDMA, or "ecstasy") is a selective serotonin neurotoxin in animals and possibly in humans. Nonhuman primates exposed to several sequential doses of MDMA, a regimen modeled after one used by humans, developed severe brain dopaminergic neurotoxicity, in addition to less pronounced serotonergic neurotoxicity. MDMA neurotoxicity was associated with increased vulnerability to motor dysfunction secondary to dopamine depletion. These results have implications for mechanisms of MDMA neurotoxicity and suggest that recreational MDMA users may unwittingly be putting themselves at risk, either as young adults or later in life, for developing neuropsychiatric disorders related to brain dopamine and/or serotonin deficiency.

Behavioral and neurochemical consequences of long-term intravenous self-administration of MDMA and its enantiomers by rhesus monkeys.

The effects of self-administered 3,4-methylenedioxymethamphetamine (MDMA) on behavior and neurochemistry have not been previously studied in laboratory primates. We investigated the capacity of MDMA and its enantiomers to maintain contingent responding over an extended duration, whether any decrements in the reinforcing effects of these compounds would be observed over time, whether such decrements would be MDMA-selective, and whether any neurochemical correlates could be identified. Animals were previously trained to self-administer cocaine, then exposed to periodic substitutions of various doses of racemic MDMA and its enantiomers; full dose-effect curves were generated for each MDMA compound repeatedly over the duration of the study. After approximately 18 months of MDMA self-administration, drug exposure was halted and after at least 2 months drug abstinence, animals were scanned using positron emission tomography (PET) with the vesicular monoamine transporter (VMAT) ligand dihydrotetrabenazine (DTBZ). Shortly thereafter, animals were euthanized, brains were dissected, and samples were assayed for brain monoamines and their metabolites using high-performance liquid chromatography (HPLC), and for VMAT using DTBZ binding. The reinforcing effects of racemic and R(-)-MDMA were reduced over a long series (months) of individual self-administration access periods; the reinforcing effects of S+-MDMA were more resistant to this effect, but were attenuated for one animal. The reinforcing effects of cocaine were not altered by chronic MDMA self-administration, nor was the VMAT binding potential as assessed by PET. Further, there were no measurable decrements in serotonin (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), dopamine (DA), 3,4-dihydroxyphenylacetic acid (DOPAC) or VMAT in any brain regions assayed. The reinforcing effects of MDMA are selectively attenuated by chronic MDMA self-administration, although this behavioral change appears to occur in the absence of any frank neurochemical correlates of toxicity.

Hoover and the Chemist have quite the "tag team" act on this board. I've seen this routine used on other boards in an attempt to bully and silence other posters. One supports the other as they gang up on any perceived opposition.

What purpose, for example, does one of their comments, "given that other contributions to this thread have been ill- or non-informed" serve? Let each reader decide for themselves how informed a post is.

Sadly,this sort of tag-team bullying is usually successful. Many posters, often hurting, in need of help and real answers, instead are drowned out unless they have sufficient references and meet the chemists' level of proof. Worn down, they leave.

And in the end, the chemists prevail - at least, in their own minds.

I speak up when misinformation is being given. I'm a toxicologist. I study this sort of thing both vocationally and avocationally. I read it as part of my job, and I read it for fun.

I'm not trying to bully or silence anybody. I'm trying to inform. I think I'm a decent judge of quality information, but please feel free to disagree, or post a dissenting position.

I don't know that chemist and I have joined our voices together on a single issue before this time, so I cannot say it is either a pattern, nor a planned act. I had the references available to me, to back up the simpler statements he had made. I'd be happy to back you up, too, if the opportunity arises.

I'd like to take this opportunity to provide a more in-depth analysis of my position vis a vis therapeutic use of MDMA.

I can best represent my feelings by discussing another drug first. If I knew of an individual dying of bone cancer (a horrible painful exit from this mortal coil), I would hope they would be prescribed a suitable pain control medication. Perhaps, I should say, *the* suitable pain control medication, heroin. For these individuals, there is no psychotropic effect. Their powerfully up-regulated mu-opioid system (from the pain stimulus) mops up the heroin first, as those nociceptive receptors have a higher affinity for the drug than do the psychotropic ones. Unfortunately, too many doctors have images of junkies and shooting galleries in their minds, and heroin is far too seldom put to this admirable use. I have heard remarkable tales of people coming back to their old selves, under the influence of the heroin, and being permitted a last and fruitful interaction with their loved ones, prior to their inevitable death. Yet, I have actually heard doctors say that they don't want to turn the sufferer into an addict, and refuse the prescription outright. As if that mattered, in that context. But, in fact, the pain itself precludes addiction (if the dose is appropriate), as addiction can only follow psychotropic effects. So even that argument is fallacious. It is a classic non sequitur, and it arises from social propaganda. Drug abuse is a property of people, not of the drug itself.

Now, with respect to MDMA. There is a similar therapeutic use of MDMA, in an appropriately selected population (e.g. sufferers of PTSD), who are psychologically prepared for the drug experience, and guided by skilled clinicians. Two of the distinctive characteristics of this process (and of the use of heroin, as above), are that the drug is supplied in a much purer form than can be obtained "on the street", and at a very precise dose. You don't know what you're getting from a street dealer, or the dose, nor can you readily obtain that information. For example, an early batch of street MDMA was contaminated with MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine), in an attempt to adulterate the MDMA with the drug meperidine (Demerol). Unfortunately for a few individuals, the MPTP was present in high enough concentrations to induce permanent Parkinson's-like symptoms. That's the problem with what we call "bucket chemists". Anybody can get a recipe off the Internet, but that doesn't turn you into a chemist....no more so than reading a recipe for duck a l'orange will turn you into a cook.

I'm not a lily-white ivory-tower demagogue. I was a hard-core addict for many years. I did more PCP than I have a right to have even survived. I know what drug abuse is. And, if I may be so bold, I know what drug abuse isn't.

One hundred years ago, Eaton's (the Canadian equivalent to Sears) sold tincture of opium, and hemp extract. The latter was for "female concerns", or something phrased similar. Lo and behold, one hundred years later, we discover that PMS and dysmennorhea may be related to cyclic depletion of endocannibinoids (our internal, natural cannabis-like chemicals). That's not to suggest that pot-smoking is always valid, but it also does not invalidate medical use of marijuana. Or of opium.

Alcohol is an excellent disinfectant, and used in moderation, reduces the risk of heart attack.... Need I go on?

The study you're quoting involves rats. You can't directly compare animal doses to human doses without first calculating the human equivalent dose (HED) which takes into account such things as body surface area. To get the HED for rats you should multiply the dose above by 0.16. So 4 mg/kg * 0.16 = 0.64 mg/kg. That's a total dose of only 38.4 mg in your 60 kg human. Repeated dosing of MDMA and amphetamines gets even more complicated because rats metabolize the drug so much faster than humans.
