			MDMA: (Ecstasy)
Chemistry, route of access and effects reported by 
users.
By: Courtney E. Allen
Ecstasy is derived from Methamphetamine and Amphetamine.  
Belonging to a class of drugs known as "designer drugs".  
Designer drugs are created by changing the molecular 
structure of an existing drug to create a new substance.  
Methylenedioxymethanphetamine (Ecstasy) is a synthetic drug 
that acts simultaneously as a stimulant and a hallucinogen.  
The emperic formula for Ecstasy is C11 H15 NO2.  In 1914 
Merck was issued a patent for MDMA, but the toxicology of 
this compound wasn't studied systematically until the early 
1950's. In 1985 MDMA was classified as a schedule I drug.  It 
was suggested that MDMA, in a controlled, therapeutic 
setting, promotes confidence and trust between patients and 
therapists (1).
  The production of this drug is fairly straightforward and 
easy to concoct.  Sarole, the active ingredient in nutmeg is 
used to prepare the starting Ketone (3,4 Methylenedioxy 
phenylopropane) by oxidizing with hydrogen peroxide in an 
acid medium.  The compound is then combined with Methylamine 
in Alcohol.  Alcohol powder treated with Mercuric chloride is 
then added and boiled for many hours.  The MDMA substance can 
then be distilled off under pressure (2).
MDMA can be swallowed, smoked, injected or "snorted".  
When Ecstasy is swallowed (usually in a capsule form) it has 
three main routes of access.  The first access is through the 
gastrointestinal system.  The second can be held under the 
tongue where it is absorbed sublingually.  Lastly it can 
remain in the mouth where it is absorbed through the mucus 
membrane.  Once the drug has entered the body it must under 
go extraction by the liver before it may feasibly reach the 
circulation system.  Once the drug reaches the systematic 
circulation it is transmitted through the blood vessel wall, 
to the brain, to the blood brain barrier.  The blood brain 
barrier is a semipermeable barrier produced by the cells in 
the walls of the capillaries in the brain.  After the initial 
circulation of the drug into the blood brain barrier the drug 
is then dispersed into other parts of the body where it has 
no pharmacological activity (3).
Ecstasy is known to stimulate the Central Nervous System 
and produce hallucinogenic effects.  These effects are 
usually characterized as a total consciousness and pure 
connection with the universe.  Ecstasy is the designer drug 
of choice by most college students at present time because 
the effects enable the user to stay awake with endless 
amounts of energy for up to 8 hours (4).
     Survivors of MDMA compare the feelings they experience 
while under the influence of the drug with the feeling of 
being in love.  These feelings will usually be empathy, 
openness, peace and caring.  It has been reported to 
transform personal relationships and boost self-esteem.  It's 
effects have been described as opening people up to their 
intuition and feelings leading to expanded sense of self-
awareness and empathy for others. Many users as well as 
survivors claim that their experience or "trip" with Ecstasy 
had changed their life in profound ways (for the better). As 
well as the positive effects experienced by users of Ecstasy 
there are also the negative side effects.  These side effects 
range from psychiatric disturbances, including panic, 
anxiety, depression and paranoid thinking.  Survivors of 
Ecstasy describe their feelings as, "Lost within one's own 
mind, with no control over reality."
	MDMA is also better known as the designer drug that 
kills many people.  It is not necessarily the drug itself 
that kills, but the effect of the drug on the body.  As 
mentioned earlier Ecstasy is the choice drug of many college 
students at raves, (all night dance parties) where users 
dance straight for many hours.  Many deaths associated with 
MDMA are caused by dehydration.  In conclusion it is very 
important for users of Ecstasy to always drink plenty of 
liquids while under the intoxication of the drug.  After all 
it is your own life you're dealing with.

MDMA
Neuron and Neurotransmitters
By: Adrian Ramirez
	This section of the group report will discuss three 
aspects of MDMA:  neurotransmitters involved, part of neuron 
affected, and its potential changes.  The neurotransmitter 
that is primarily affected by MDMA is serotonin.  But before 
I get into that, let's take a look at what serotonin is and 
what role it plays so that you can better understand where 
MDMA comes into the picture.
 	Serotonin is a neurotransmitter that is found in the 
brain (2%) and other places like blood platelets and the 
gastrointestinal tract muscles (98%) (6).  Like all other 
neurotransmitters, serotonin carries messages between 
neurons.  In a presynaptic neuron an all or none impulse 
activates and opens the calcium channels of a terminal bouton 
to let calcium ions enter.  This causes synaptic vesicles, 
which contain the neurotransmitter, to fuse with the membrane 
of the terminal bouton and release the neurotransmitter into 
the synaptic cleft.  As it diffuses across the synaptic cleft 
a couple of things happen to serotonin: some of it binds to 
the receptors of a post synaptic membrane, some of it is 
destroyed, and some of it is sucked back into the neuron that 
released it by a process called reuptake (1).  
	MDMA has been shown to inhibit the reuptake of 
serotonin, which means that it remains in the synaptic cleft 
and the message gets amplified (9).  A reduction in the 
density of serotonin uptake carriers is exhibited, and this 
has shown to cause a loss of serotonin nerve terminals (8).  
MDMA has also been found to cause an increase of serotonin to 
be released by the terminal bouton into the synaptic cleft.  
So not only would serotonin not be taken away from the 
synaptic cleft, but there would be more of it being
released in the first place (9).  
	When a person is on MDMA serotonin levels are high
because neurons are working extremely harder than they
normally do.  But even though serotonin levels are high
while on MDMA, the high is over a day or two later and there 
is a significant decrease in serotonin levels.  The neurons 
are put to work for so such an extended amount of time that 
naturally in the next couple of days the neurons of that 
individual produce a low serotonin count.  Regular users can 
drop a third in the level of serotonin derived chemicals in 
their spinal fluid (9).  Furthermore, nonhuman primates have 
shown to have a reduction (21%) in serotonin in the thalamus 
and a reduction (16%) in the hypothalamus two weeks after 
dosing on MDMA (10).  
	In another study, rats displayed progressive decreases 
of tissue levels of serotonin and its metabolite 24 hours 
after a single injection of a high dose (8).  Studies on rats 
have also shown that MDMA selectively destroys serotonin in 
the brain stem, cortex, striatum, and hippocampus (3).  
Serotonin levels in the brain reduced 73% to 94%, and 42% to 
45% in the spinal cord in a study where 55 squirrel monkeys 
were given MDMA (5mg/kg) twice daily for four days (8).  
	The other neurotransmitter shown to be significantly 
affected by MDMA is dopamine.  When there are low marked 
serotonin levels, from the MDMA high being over, dopamine is 
absorbed by the serotonal receptors.  Since dopamine 
shouldn't be here, a toxic metabolite created by an enzyme 
breaks it down.  This causes damage to the terminals of the 
nerve cell.  In one study, decreased levels of dopamine in 
the striatum of rats emerged for a few hours after MDMA doses 
were given (6).  In another study, dopamine, serotonin, and 
norepinephrine levels were measured in the striatum, 
neocortex, hippocampus, and hypothalamus after
rats were given a dose of MDMA.  Dopamine and norepinephrine 
levels were reduced only from the highest doses, but 
serotonin levels were reduced at a low dose in all regions.  
In addition, it reduced serotonin uptake two weeks after 
administration of MDMA (3).  
	As you can see from some of the effects that MDMA has on 
neurotransmitters, the neurons involved in the activity of 
those neurotransmitters are also very much affected.  It has 
been found that in doses known to evoke the MDMA 
psychological syndrome in man, MDMA decreases the firing rate 
of some serotonergic neurons in rats (5).  In a series of 
studies conducted with rats and nonhuman primates, doses 
slightly higher than those taken by humans significantly 
damaged serotonergic neurons.  It was also reported that 12 
to 18 months after the brains of squirrel monkeys had been 
damaged by MDMA, nerve fibers that produce serotonin had 
abnormally regrown in some areas of the brain and had failed 
to regrow at all in others (2).
	Silver staining techniques have also revealed evidence 
of neuronal damage.  Abnormal inclusions within the cell 
bodies of dorsal raphe nucleus cells were found in rhesus 
monkeys injected with MDMA (5mg/kg) twice daily for four 
days.  Fine fibre serotonergic axons, in both rats and 
monkeys, seen through immunostaining were mostly swollen and 
broken up in pieces.  Another method, called 
immunohistochemical staining, has shown that MDMA decreases 
the number of serotonin antibody positive nerve fibers. Most 
vulnerable to MDMA were the fine fibre type ascending axons 
from the dorsal raphe nucleus (8).
	In contrast to prior evidence, long term effects of MDMA 
are less notable.  Pictures of serotonergic neurons of a 
brain cortex appear to show the normal amount of serotonin 
staining one year after dosing MDMA. This suggests that there 
is no decrease in the serotonin levels of this brain region 
of the rat one year after exposure (11).  Studies conducted 
by the US Environmental Protection Agency (EPA) on rats and 
mice have not observed any damage to serotonergic neurons due 
to MDMA.  Furthermore, senior researchers for the US EPA 
express that prolonged decreases in brain serotonin cannot be 
grounds to conclude that actual neuronal structures 
themselves are destroyed.  This means that MDMA can decrease 
the levels of serotonin without destroying serotonergic 
axons.  Studies used to mark whether serotonergic axons are 
still functioning after serotonin is drained have not yet 
been conducted following MDMA exposure to rats or primates 
(7).
	There is no direct evidence confirming that MDMA 
decreases serotonin in humans.  Spinal taps, brain scans, and 
injections of radioactive substances would have to be used in 
studies to directly measure whether or not it causes 
serotonin reductions.  This is more dangerous than MDMA 
itself.  The best indirect evidence on humans is a study done 
by Dr. McCann and Dr. Ricaurte in which the long term effects 
of MDMA on experienced users was evaluated.  They found that 
a group of users, who used the drug an average of 95 times, 
had about 32% less serotonin metabolite in their
spinal fluid on average than the control groups.  Being that 
the range of serotonin metabolites in spinal fluid is quite 
large, 32% is relatively not a significant
difference (10).  No differences were observed in a small 
scale study where researchers compared cerebrospinal fluid 
levels of five MDMA users to controls (8).
	A couple of other factors to consider after reading this 
section is that findings from nonhuman studies on MDMA are 
being used to form hypothesis about it's effects on humans.  
However, no definite conclusions are being made because there 
are significant species dependent difference in response to 
any drug.  Rats, mice, and primates all respond differently 
in some studies.  So far primate studies
on MDMA aremost useful in assessing it's effects on humans, 
but even these findings have to be validated by human 
research (4).

Complete Physiological and Side effect changes
By: Joseph Segal
The average dose of "ecstasy" ranges from 100 to 150 
milligrams (1). There are two major effects of MDMA the 
mental effects and the amphetamine effects. The mental 
effects are emotional closeness, insight, improved 
communication, and empathy. Users of MDMA may be attracted to 
the drug because they feel that it has the ability to 
increase empathy and self insight. Advantages of MDMA over 
traditional psychedelics are less distortion of sensory 
perception and fewer unpleasant emotional reactions (2). Many 
individuals describe strong euphoric and sensual effects 
associated with MDMA. Most users describe a dramatic drop in 
defense mechanisms and increased empathy towards others. 
Combined with the amphetamine effects this may heighten or 
intensify intimate communication. Another desired effect of 
MDMA is that clarity of thought and concentration is believed 
to be increased. This may be due to the high level of 
serotonin that the drug increases. Because nerve endings may 
become numb as a result of the drug, the feeling of enhanced 
sensuality may be because all things touched may feel softer 
than normal, but of course when nerve endings are numb 
tactile senses actually desensitize (7).
	With increased use of MDMA the desired mental effects 
tend to decrease because the serotonin has been overused. 
Therefore, less serotonin exists in the terminal for MDMA to 
take advantage. Since serotonin is being overworked and its 
functions are involved with pleasure, a person may feel 
pleasure in nearly every way possible for example: dancing, 
touching, communicating and thinking (4). 
	Of course there are negative and undesired mental 
effects. These effects are psychiatric disturbances, which 
include panic, anxiety, depression and paranoia.
The physiological effects tend to appear within 20-60 minutes 
after ingestion. The user generally experiences a "rush" of 
energy caused by increased heart rate. This is described as 
mild but can give a sense of well being. After this surge in 
energy, the high begins to level off which lasts 2-3 hours, 
the user gradually begins coming down, and this results in a 
feeling of fatigue. The feeling of fatigue or as some would 
say "relaxed" causes users to be unaware of the stimulant 
side effects (7). Another physiological effect of people who 
over abuse MDMA seem to experience a lower sexual drive. The 
other undesirable physiological effects are caused by the 
amphetamine part of the drug. These effects are high blood 
pressure, insomnia, high pulse rate, dilated pupils, and 
rapid oscillation of the eyeballs (nystagmus) (5). If dosage 
is increased the undesired effects increase, but the desired 
euphoric effects decrease with higher dosage. The amphetamine 
effects remain potent and the mental effects drop off with 
repeated use. Other undesired physiological effects of MDMA 
may include respiratory distress, edema, hypothermia, and 
temporary kidney stoppage (oliguria). Many users also claim 
to be severely dehydrated while using MDMA. This may be due 
to the oliguria. The more common physiological effects are 
muscle tension, sleep problems, sweating, chills, blurred 
vision, fainting, nausea, hallucinations, tremors, and 
increased pulse (8).
	Side effects while using this drug are quite common 
especially with the amphetamine compound of MDMA. These side 
effects are dilated pupils, tension in the jaw, grinding of 
the teeth, and dry mouth. Many users claim headaches while 
under the influence of this drug, with another common side 
effect being aching muscles (3). Because of the over 
productivity of serotonin, the days after will show a 
depletion of serotonin. Low serotonin may result in 
depression. MDMA stimulates the central nervous system and 
produces hallucinations. Unfortunately, there may be more 
severe side effects. For example, studies with rats and 
monkeys have shown that the use of MDMA may reduce the level 
of serotonin in the brain by as much as 90% for at least two 
weeks (2). Serotonin effects thinking, mood, sexual function, 
sensitivity to pain and eating habits. So continued abuse of 
this drug may cause dysfunction in either one or all of these 
areas (8).
	In conclusion, MDMA otherwise known as Ecstasy is a 
designer drug, which plays many psychological and 
physiological effects on the body and mind. Evidence has 
shown various results which display what the drug can do, 
specifically inside the brain. Keep in note that further 
evidence has to be found in order to make any further 
conclusions.
