MDMA - Esctasy

How Is MDMA Abused?
MDMA is taken orally, usually as a capsule or tablet. It was initially popular among Caucasian adolescents and young adults in the nightclub scene or at weekend-long dance parties known as raves. More recently, the profile of the typical MDMA user has changed, with the drug now affecting a broader range of ethnic groups. MDMA is also popular among urban gay males— some report using MDMA as part of a multiple-drug experience that includes marijuana, cocaine, methamphetamine, ketamine, and other legal and illegal substances.

How Does MDMA Affect the Brain?
MDMA exerts its primary effects in the brain on neurons that use the chemical (or neurotransmitter) serotonin to communicate with other neurons. The serotonin system plays an important role in regulating mood, aggression, sexual activity, sleep, and sensitivity to pain. MDMA binds to the serotonin transporter, which is responsible for removing serotonin from the synapse (or space between adjacent neurons) to terminate the signal between neurons. MDMA also causes excessive release of serotonin from neurons containing the neurotransmitter, and it has similar but less potent effects on neurons that contain dopamine and norepinephrine.

MDMA can produce confusion, depression, sleep problems, drug craving, and severe anxiety. These problems can occur soon after taking the drug or, sometimes, even days or weeks after taking MDMA. In addition, chronic users of MDMA perform more poorly than nonusers on certain types of cognitive or memory tasks, although some of these effects may be due to the use of other drugs in combination with MDMA. Research in animals indicates that MDMA can be harmful to the brain—one study in nonhuman primates showed that exposure to MDMA for only 4 days caused damage to serotonin nerve terminals that was still evident 6 to 7 years later.1 Although similar neurotoxicity has not been shown definitively in humans, the wealth of animal research indicating MDMA’s damaging properties strongly suggests that MDMA is not a safe drug for human consumption. This is currently an area of active research.

Addictive Potential
For some people, MDMA can be addictive.2 A survey of young adult and adolescent MDMA users found that 43 percent of those who reported ecstasy use met the accepted diagnostic criteria for dependence, as evidenced by continued use despite knowledge of physical or psychological harm, withdrawal effects, and tolerance (or diminished response).3 These results are consistent with those from similar studies in other countries that suggest a high rate of MDMA dependence among users.4 MDMA abstinence-associated withdrawal symptoms include fatigue, loss of appetite, depressed feelings, and trouble concentrating.2

What Other Adverse Effects Does MDMA Have on Health?
MDMA can also be dangerous to overall health and, on rare occasions, lethal. MDMA can have many of the same physical effects as other stimulants, such as cocaine and amphetamines. These include increases in heart rate and blood pressure—which present risks of particular concern for people with circulatory problems or heart disease—and other symptoms such as muscle tension, involuntary teeth clenching, nausea, blurred vision, faintness, and chills or sweating.

In high doses, MDMA can interfere with the body’s ability to regulate temperature. On rare but unpredictable occasions, this can lead to a sharp increase in body temperature (hyperthermia), which can result in liver, kidney, cardiovascular system failure, or death. MDMA can interfere with its own metabolism (breakdown within the body); therefore, potentially harmful levels can be reached by repeated MDMA administration within short periods of time. Other drugs that are chemically similar to MDMA, such as MDA (methylenedioxyamphetamine, the parent drug of MDMA) and PMA (paramethoxyamphetamine, associated with fatalities in the United States and Australia),5 are sometimes sold as ecstasy. These drugs can be neurotoxic or create additional health risks to the user. Furthermore, ecstasy tablets may be mixed with other substances, such as ephedrine (a stimulant); dextromethorphan (DXM, a cough suppressant); ketamine (an anesthetic used mostly by veterinarians); caffeine; cocaine; and methamphetamine. Although the combination of MDMA with one or more of these drugs may be inherently dangerous, users who also combine these with additional substances such as marijuana and alcohol may be putting themselves at even higher risk for adverse health effects.

What Treatment Options Exist?
There are no specific treatments for MDMA abuse and addiction. The most effective treatments for drug abuse and addiction in general are cognitive-behavioral interventions that are designed to help modify the patient’s thinking, expectancies, and behaviors related to their drug use and to increase skills in coping with life stressors. Drug abuse recovery support groups may also be effective in combination with behavioral interventions to support long-term, drug-free recovery. There are currently no pharmacological treatments for addiction to MDMA.

How Widespread Is MDMA Abuse?
Monitoring the Future Survey*
While MDMA use is not rising currently, MTF investigators remain concerned because the perceived risk associated with MDMA use has been in decline for several years and may leave young people open to renewed interest in it. In fact, 10th-graders’ and 12th-graders perceived harmfulness dropped significantly between 2008 and 2009. In 2008, 43.2 percent of 10th-graders associated harmfulness with trying MDMA once or twice; in 2009, this percentage fell to 38.9.
