Q.) What is Ecstasy?
A.) MDMA or ecstasy is a Schedule I synthetic,
psychoactive drug possessing stimulant and hallucinogenic
properties. Ecstasy possesses chemical variations of the
stimulant amphetamine or methamphetamine and a hallucinogen,
most often mescaline. Commonly referred to as Ecstasy or XTC,
MDMA was first synthesized in 1912 by a German company
possibly to be used as an appetite suppressant. Chemically, it
is an analogue of MDA, a drug that was popular in the 1960s.
In the late 1970s, MDMA was used to facilitate psychotherapy
by a small group of therapists in the
United
States. Illicit use of the
drug did not become popular until the late 1980s and early
1990s. Ecstasy is frequently used in combination with other
drugs. However, it is rarely consumed with alcohol, as alcohol
is believed to diminish its effects. It is most often
distributed at late-night parties called "raves", nightclubs,
and rock concerts. As the rave and club scene expands to
metropolitan and suburban areas across the country, ecstasy
use and distribution are increasing as well.

Q.) How is Ecstasy used?
A.) Ecstasy is most often available in tablet form and
is usually ingested orally. It is also available as a powder and is
sometimes snorted and occasionally smoked, but rarely injected. Its
effects last approximately four to six hours. Users of the drug say
that it produces profoundly positive feelings, empathy for others,
elimination of anxiety, and extreme relaxation. Ecstasy is also said
to suppress the need to eat, drink, or sleep, enabling users to
endure two- to three-day parties. Consequently, ecstasy use
sometimes results in severe dehydration or exhaustion.
Q.) Where does Ecstasy come
from?
A.) Clandestine laboratories operating throughout
Western Europe, primarily the
Netherlands
and
Belgium,
manufacture significant quantities of the drug in tablet, capsule,
or powder form. Although the vast majority of ecstasy consumed
domestically is produced in Europe, a limited
number of ecstasy labs operate in the
United
States. In addition, in recent
years, Israeli organized crime syndicates, some composed of Russian
émigrés associated with Russian organized crime syndicates, have
forged relationships with Western European traffickers and gained
control over a significant share of the European market. The Israeli
syndicates are currently the primary source to
U.S.
distribution groups.
Overseas ecstasy trafficking organizations smuggle the
drug in shipments of 10,000 or more tablets via express mail
services, couriers aboard commercial airline flights, or, more
recently, through air freight shipments from several major European
cities to cities in the United States. The drug is sold in bulk
quantity at the mid-wholesale level in the
United
States for approximately eight
dollars per dosage unit. The retail price of ecstasy sold in clubs
in the United
States remains steady at twenty to
thirty dollars per dosage unit. Ecstasy traffickers consistently use
brand names and logos as marketing tools and to distinguish their
product from that of competitors. The logos are produced to coincide
with holidays or special events. Among the more popular logos are
butterflies, lightning bolts, and four-leaf
clovers.
Q.) What are the short-term effects of
Ecstasy?
A.) While it is not as addictive as heroin or cocaine,
ecstasy can cause other adverse effects including nausea,
hallucinations, chills, sweating, increases in body temperature,
tremors, involuntary teeth clenching, muscle cramping, and blurred
vision. Ecstasy users also report after-effects of anxiety,
paranoia, and depression. An ecstasy overdose is characterized by
high blood pressure, faintness, panic attacks, and, in more severe
cases, loss of consciousness, seizures, and a drastic rise in body
temperature. Ecstasy overdoses can be fatal, as they may result in
heart failure or extreme heat stroke.
The effects start after about 20 minutes and can last
for hours. These is a 'rush' feeling followed by a feeling of calm
and a sense of well being to those around, often with a heightened
perception of color and sound. Some people actually feel sick and
experience a stiffening up of arms, legs and particularly the jaw
along with sensations of thirst, sleeplessness, depression and
paranoia. Gives a feeling of energy. Some mild hallucinogenic
effects.
Many problems users encounter with Ecstasy are similar
to those found with the use of amphetamines and cocaine. They
include increases in heart rate and blood pressure, nausea, blurred
vision, faintness, chills, sweating, and such psychological problems
as confusion, depression, sleep problems, craving, severe anxiety,
paranoia, and psychotic episodes. Ecstasy's chemical cousin, MDA,
destroys cells that produce serotonin in the brain. These cells play
a direct roll in regulating aggression, mood, sexual activity,
sleep, and sensitivity to pain. Methamphetamine, also similar to
Ecstasy, damages brain cells that produce dopamine. Scientists have
now shown that ecstasy not only makes the brain's nerve branches and
endings degenerate, but also makes them "re-grow, but abnormally -
failing to reconnect with some brain areas and connecting elsewhere
with the wrong areas. These reconnections may be permanent,
resulting in cognitive impairments, changes in emotion, learning,
memory, or hormone-like chemical
abnormalities.
Q.) What are the long-term effects of
Ecstasy?
A.) The designer drug "Ecstasy," or MDMA, causes
long-lasting damage to brain areas that are critical for thought and
memory, according to new research findings in the June 15 issue of
The Journal of Neuroscience. In an experiment with red squirrel
monkeys, researchers at The Johns Hopkins University demonstrated
that 4 days of exposure to the drug caused damage that persisted 6
to 7 years later. These findings help to validate previous research
by the Hopkins team in
humans, showing that people who had taken ecstasy scored lower on
memory tests.
"The serotonin system, which is compromised by
ecstasy, is fundamental to the brain's integration of information
and emotion," says Dr. Alan I. Leshner, director of the National
Institute on Drug Abuse (NIDA), National Institutes of Health, which
funded the research. "At the very least, people who take ecstasy,
even just a few times, are risking long-term, perhaps permanent,
problems with learning and memory."
The researchers found that the nerve cells (neurons)
damaged by ecstasy are those that use the chemical serotonin to
communicate with other neurons. The
Hopkins team had also
previously conducted brain imaging research in human ecstasy users,
in collaboration with the National Institute of Mental Health, which
showed extensive damage to serotonin neurons.
MDMA (3,4-methylenedioxymethamphetamine) has a
stimulant effect, causing similar euphoria and increased alertness
as cocaine and amphetamine. It also causes mescaline-like
psychedelic effects. First used in the 1980s, MDMA is often taken at
large, all-night "rave" parties.
In this new study, the
Hopkins researchers
administered either MDMA or salt water to the monkeys twice a day
for 4 days. After 2 weeks, the scientists examined the brains of
half of the monkeys. Then, after 6 to 7 years, the brains of the
remaining monkeys were examined, along with age-matched controls.
In the brains of the monkeys examined soon after the
2-week period, Dr. George Ricaurte and his colleagues found that
MDMA caused more damage to serotonin neurons in some parts of the
brain than in others. Areas particularly affected were the neocortex
(the outer part of the brain where conscious thought occurs) and the
hippocampus (which plays a key role in forming long-term memories).
This damage was also apparent, although to a lesser
extent, in the brains of monkeys who had received MDMA during the
same 2-week period but who had received no MDMA for 6 to 7 years. In
contrast, no damage was noticeable in the brains of those who had
received salt water. "Some recovery of serotonin neurons was
apparent in the brains of the monkeys given MDMA 6 to 7 years
previously," says Dr. Ricaurte, "but this recovery occurred only in
certain regions, and was not always complete. Other brain regions
showed no evidence of recovery whatsoever."
A
NIDA-supported study has provided the first direct evidence that
chronic use of MDMA, popularly known as "ecstasy," causes brain
damage in people. Using advanced brain imaging techniques, the study
found that MDMA harms neurons that release serotonin, a brain
chemical thought to play an important role in regulating memory and
other functions. In a related study, researchers found that heavy
MDMA users have memory problems that persist for at least 2 weeks
after they have stopped using the drug. Both studies suggest that
the extent of damage is directly correlated with the amount of MDMA
use.
"The message from these studies is that MDMA does
change the brain and it looks like there are functional consequences
to these changes," says Dr. Joseph Frascella of NIDA's Division of
Treatment Research and Development. That message is particularly
significant for young people who participate in large, all-night
dance parties known as "raves," which are popular in many cities
around the Nation. NIDA's epidemiologic studies indicate that MDMA
(3,4-methylenedioxymethamphetamine) use has escalated in recent
years among college students and young adults who attend these
social gatherings.
These brain scans show the amount of serotonin
activity over a 40-minute period in a non-MDMA user (left) and an
MDMA user (right). Dark areas in the MDMA user's brain show damage
due to chronic MDMA use.
In the brain imaging study, researchers used positron
emission tomography (PET) to take brain scans of 14 MDMA users who
had not used any psychoactive drug, including MDMA, for at least 3
weeks. Brain images also were taken of 15 people who had never used
MDMA. Both groups were similar in age and level of education and had
comparable numbers of men and women.
In people who had used MDMA, the PET images showed
significant reductions in the number of serotonin transporters, the
sites on neuron surfaces that reabsorb serotonin from the space
between cells after it has completed its work. The lasting reduction
of serotonin transporters occurred throughout the brain, and people
who had used MDMA more often lost more serotonin transporters than
those who had used the drug less.
Previous PET studies with baboons also produced images
indicating MDMA had induced long-term reductions in the number of
serotonin transporters. Examinations of brain tissue from the
animals provided further confirmation that the decrease in serotonin
transporters seen in the PET images corresponded to actual loss of
serotonin nerve endings containing transporters in the baboons'
brains. "Based on what we found with our animal studies, we maintain
that the changes revealed by PET imaging are probably related to
damage of serotonin nerve endings in humans who had used MDMA," says
Dr. George Ricaurte of The Johns Hopkins Medical Institutions in
Baltimore. Dr. Ricaurte
is the principal investigator for both studies, which are part of a
clinical research project that is assessing the long-term effects of
MDMA.
"The real question in all imaging studies is what
these changes mean when it comes to functional consequences," says
NIDA's Dr. Frascella. To help answer that question, a team of
researchers, which included scientists from Johns Hopkins and the
National Institute of Mental Health who had worked on the imaging
study, attempted to assess the effects of chronic MDMA use on
memory. In this study, researchers administered several standardized
memory tests to 24 MDMA users who had not used the drug for at least
2 weeks and 24 people who had never used the drug. Both groups were
matched for age, gender, education, and vocabulary scores.
The study found that, compared to the nonusers, heavy
MDMA users had significant impairments in visual and verbal memory.
As had been found in the brain imaging study, MDMA's harmful effects
were dose-related the more MDMA people used, the greater difficulty
they had in recalling what they had seen and heard during testing.
The memory impairments found in MDMA users are among
the first functional consequences of MDMA-induced damage of
serotonin neurons to emerge. Recent studies conducted in the
United
Kingdom also have reported memory
problems in MDMA users assessed within a few days of their last drug
use. "Our study extends the MDMA-induced memory impairment to at
least 2 weeks since last drug use and thus shows that MDMA's effects
on memory cannot be attributed to withdrawal or residual drug
effects," says Dr. Karen Bolla of Johns Hopkins, who helped conduct
the study.
The Johns Hopkins/NIMH researchers also were able to
link poorer memory performance by MDMA users to loss of brain
serotonin function by measuring the levels of a serotonin metabolite
in study participants' spinal fluid. These measurements showed that
MDMA users had lower levels of the metabolite than people who had
not used the drug; that the more MDMA they reported using, the lower
the level of the metabolite; and that the people with the lowest
levels of the metabolite had the poorest memory performance. Taken
together, these findings support the conclusion that MDMA-induced
brain serotonin neurotoxicity may account for the persistent memory
impairment found in MDMA users, Dr. Bolla says.
Research on the functional consequences of
MDMA-induced damage of serotonin-producing neurons in humans is at
an early stage, and the scientists who conducted the studies cannot
say definitively that the harm to brain serotonin neurons shown in
the imaging study accounts for the memory impairments found among
chronic users of the drug. However, "that's the concern, and it's
certainly the most obvious basis for the memory problems that some
MDMA users have developed," Dr. Ricaurte says.
Findings from another Johns Hopkins/NIMH study now
suggest that MDMA use may lead to impairments in other cognitive
functions besides memory, such as the ability to reason verbally or
sustain attention. Researchers are continuing to examine the effects
of chronic MDMA use on memory and other functions in which serotonin
has been implicated, such as mood, impulse control, and sleep
cycles. How long MDMA-induced brain damage persists and the
long-term consequences of that damage are other questions
researchers are trying to answer. Animal studies, which first
documented the neurotoxic effects of the drug, suggest that the loss
of serotonin neurons in humans may last for many years and possibly
be permanent. "We now know that brain damage is still present in
monkeys 7 years after discontinuing the drug," Dr. Ricaurte says.
"We don't know just yet if we're dealing with such a long-lasting
effect in people."
Q.) Is Ecstasy addictive?
A.) Ecstasy users may encounter problems similar to
those experienced by amphetamine and cocaine users, including
addiction. In addition to its seemingly rewarding effects, ecstasy's
psychological effects can include confusion, depression, sleep
problems, anxiety, and paranoia during, and sometimes weeks after,
taking the drug. Physical effects can include muscle tension,
involuntary teeth-clenching, nausea, blurred vision, faintness, and
chills or sweating. Increases in heart rate and blood pressure are a
special risk for people with circulatory or heart disease.
Ecstasy-related fatalities at raves have been reported. The
stimulant effects of the drug, which enable the user to dance for
extended periods, combined with the hot, crowded conditions usually
found at raves can lead to dehydration, hyperthermia, and heart or
kidney failure. Ecstasy use damages brain serotonin neurons.
Serotonin is thought to play a role in regulating mood, memory,
sleep, and appetite. Recent research indicates heavy ecstasy use
causes persistent memory problems in humans.
