Not entirely convinced by your stress hypothesis. If all MDMA-induced damage came from acute stress as a result of little food/drink & excessive dancing, then you could take high doses - stay hydrated and minimize exercise - without experiencing anything negative. It's kind of obvious that is not the case. Enough rats have had their brains fried (5mg/kg - multiple doses), and analyzed, to reveal serotonin abnormalities that usually take 2-3 weeks to recover. The drug itself does produce central toxic metabolites, just like many other substances, and it's certainly not nontoxic. Then again, the neurotoxic effects of MDMA really aren't very prominent at usual recreational doses (1-2mg/kg), so I agree with you somewhat. Not all stress is a bad thing. Exercise is regarded as a 'stressor' yet the neurobiology proffers a paradoxical effect. That is, those that chronically exercise are more psychologically equipped to deal with negative stressors in their life (work deadlines, emotional problems etc).
I do agree that HPA axis dysfunction, caused by high-dose MDMA, could contribute to the hangover. But it's certainly not the only contribution.
The changes in cortisol for a calm setting vs. rave setting are significant. This study: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2826870/ Shows that in a labratory setting the base cortisol after taking ecstasy increases by about 150%, while in a rave setting it is about an 800% increase. That is a ridiculous amount of cortisol that your body releases to help maintain homoestasis in the body. Without a strong stress response, your body could easily go into a state of dysfunction, or chronic low grade fight or flight response.
I never said all stress is bad, but the stress from the drug is extreme,
I mainly think that the real problem is the amygdala, more specifically, amygdala trauma. The hypofunctioning hpa axis is secondary problem.
When a stressful event occurs the amygdala can become hyper-reactive to any symptoms detected in the body
This conditioning happens unconsciously without a person actually realizing it is happening.
From then on, the amygdala continually over-stimulates the sympathetic nervous system directly
The sympathetic nervous system is the emergency response of the body to threats. When it is triggered, the parasympathetic nervous system is switched off and energy is diverted to the emergency.
It over-stimulates the hypothalamus and the whole HPA (Hypothalamic-Pituitary- Adrenal) Axis, which subsequently downgrades as a result, making it difficult for the body to respond to stress.
The amygdala also over-stimulates the whole brain, keeping many brain circuits in a state of hyper-arousal. This adversely affects the levels of neurotransmitters in the brain, including serotonin and dopamine.
You saying the drug is relatively non toxic is false though. MDMA is well known among most credible researches to be neuro toxic. I mean it is usually one of the first things pointed out with the drug. You don't usually read about neuro toxicity with other drugs when researching them, but with MDMA it always comes up. 90% of my rolls have been at a rave setting so i am sure that caused more stress and over stimulation to my brain, but even if i rolled at home i'm sure i'd run into problems just not to the same degree.
Also people get anxiety , derealization, etc etc because their serotonin system has been altered so quickly. Serotonin has a large role in many brain functions, perception being one of them. If you are perceiving things differently all the time it will cause anxiety and derealization / DP.
Well I answered most your question in my first response. As far as MDMA being toxic, I said relatively because many types of drugs are neurooxic but that doesn't really mean much. Most of the negative effects on the brain that MDMA exhibits are only temporary.
