There is plenty of research on MDMA.
Many different studies point to the same general conclusions.
The debate on neurotoxicity is not really a debate, in the scientific field.
While the definition of the term 'toxic' is not set in stone, several other things have reached the status of absolute truth in the eyes of science.
MDMA causes LONG-lasting/permanent alterations in the serotonin innervation in the brains of many different mammals, especially if high or repeated doses are used.
In humans, MDMA has been shown to cause decreases in blood flow in multiple brain regions, lasting long after the drug is out of the body. Some users also experience subsequent increases in regional blood flow, sometimes lasting many months. This is believed to be a marker of 'toxicity'.
Somehow, this yo-yo effect of blood decrease and increase eventually evens out, so that the brain exhibits symmetrical distribution of blood. This can take over a year. How this is accomplished is not well known, but there is evidence that two things are going on. Re-innervation of serotonin axons is happening. Other neurotransmitter systems may also be going through modifications. Consider the reports of 'head-pressure' and 'brain zaps' which are common on Bluelight...
Even before MDMA was researched at all, it was well known that serotonin in the brain had a STRONG effect upon blood distribution.
Although the field of neuroscience still has a long way to go, even blood distribution has been proven to be a common denominator in healthy brains. Thousands upon thousands of MRI scans agree - a healthy person will have even average blood distribution throughout the brain. When a scan reveals something different, scientists try to interpret what the problem is. But it is clearly understood that blood distribution is SUPPOSED to be even.
Other studies show that most users discontinue their use eventually.
Long-term heavy use is generally defined as 200-400 pills lifetime. Few studies mention users that have surpassed this range. This is an indication that 'magic' is lost.
Many studies have attempted to show a change in the neuro-endocrine response to MDMA, tryptophan, or other serotonin agents. Some studies have shown that even after a LONG period of abstinence (2.5 years) former MDMA users no longer respond to MDMA like new users. They still experience a large increase in cortisol, but show a greatly reduced prolactin response. This prolactin/oxytocin response to MDMA is associated with the effects after you peak. This study is a clear indication that modifications have occurred, and that they are long lasting.
The truth is that YES, magic can be lost.
How permanent this is will vary from user to user and is likely mediated by a variety of factors. There are no studies examining extremely long term abstinence, yet. But rest assured, that waiting a few months is NOT likely to return the magic. If you have lost the magic, two years sounds like the minimum time to wait.
Also, understand that the 'magic' is not really the drug.
The 'magic' is the brain-gut connection. The innervation that connects your intestines to your brain is what this drug is targeting. The serotonin system is one of the MOST complex of all nerve systems, in ALL of biology. This vast network of nerves CAN be damaged and altered. Why would anyone want to believe otherwise?
A simple reason: They love the drug and they want very badly for it to be safe.
Just because you think you have enough experience to proclaim that your use of MDMA is without consequence, does not mean you are correct. Even those that have been rolling for years do NOT represent proof that there is still a debate. The debate is largely settled. Science is only trying to understand more detail at this point.
Do yourselves a favor and read the research.
There are clear indications that magic can be lost, without restoration even after long periods of abstinence.
There are clear indications that users of MDMA are at much higher risk of mood disorders or clinically significant psychological problems.
There are clear indications that repeated dosing increases the damage that is done.
Can you imagine a fate worse than 'loss of magic'?
There are many accounts of the recovery process on bluelight and erowid.
Rest assured that 'loss of magic' is the least of our concern.
There is a LOT more to worry about than not rolling ever again.
Try living with anxiety, depression, increased pressure in parts of your brain, alterations to your vision, your appetite, and your bowel movements. There is also sexual dysfunction, such as complete absence of sensation, difficulty achieving erection, and complete absence of sensation during orgasm. You may also live with the constant obsession that these symptoms are going to permanent. In fact, I have found this to be very common among those in the initial stages of recovery. There is a period of absolute panic/obsession in which you truly come to believe that you will NEVER get better. It is terrifying.
The good news is, that after 6 months, I can personally say that most of these symptoms do start to taper off. Life is slowly returning to normal.
The head-pressure is still present daily, but it is tolerable. The ability to digest food has improved significantly, but the intestines still do not feel the same. Sexual function has improved a lot, but orgasms are still not the same. There seems to be a delay of several minutes before the 'rush' of pleasure really hits the brain.
And yes, I have serious doubts that I will ever get the 'magic' back.
And just so the readers know, I have done 30 tabs or LESS in my lifetime.
It was rolling two weekends in a row, 2.5 tabs each weekend, that got me where I am now. These were tested pure on pillreports.
Do yourselves a favor and learn from other's mistakes.
Limit your rolls to twice a year, max.
Take loads of VIT C and other anti-oxidants before, during, and after your roll. Do NOT redose.
If you chose to redose anyways, keep it SMALL and do it within two hours of the initial dose. You should NEVER need more than 350mg in a night.
This could be 3 tabs, or this could be 1 tab. Make sure you know your dose and the purity, in advance.
And realize that the 'magic' is not the drug. The 'magic' is in you.
