NIDA InfoFacts

MDMA (Ecstasy)

June 2009

MDMA (3,4 methylenedioxymethamphetamine) is a synthetic, psychoactive drug that is chemically similar to the stimulant methamphetamine and the hallucinogen mescaline. MDMA produces feelings of increased energy euphoria, emotional warmth, and distortions in time perception and tactile experiences.

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 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 its neurons and 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, and cardiovascular system failure, and 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 that also combine these with additional substances such as marijuana and alcohol, may be putting themselves at even higher risk.

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 (MTF) Survey*

Between 2005 and 2008, past-year abuse of MDMA increased among 12th-graders, from 3.0 percent to 4.3 percent; and between 2004 and 2008, past-year abuse of MDMA increased among 10th-graders, from 2.4 percent to 2.9 percent.

MDMA Use by Students
Monitoring the Future Survey, 2008

  8th Grade 10th Grade 12th Grade
Lifetime** 2.4% 4.3% 6.2%
Past Year 1.7 2.9 4.3
Past Month 0.8 1.1 1.8

For the third year in a row, fewer of the younger students surveyed reported that they perceived great risk associated with MDMA use. The proportion of 8th-graders who perceived risk of harm from using MDMA "occasionally" decreased significantly, from 52 percent in 2006 to 46.8 percent in 2008; this proportion also fell significantly among 10th-graders, from 71.3 percent in 2006 to 66.4 percent in 2008. Perceived risk of MDMA use among 12th-graders decreased slightly, from 59.3 percent in 2006 to 57.0 percent in 2008.

National Survey on Drug Use and Health (NSDUH)***

In 2007, an estimated 503,000 people (0.2 percent of the population) in the United States aged 12 or older used MDMA in the month prior to being surveyed. Lifetime use increased among individuals aged 12 years or older, from 4.3 percent (10.2 million) in 2002 to 5.0 percent (12.4 million) in 2007; however, past-year use of ecstasy decreased from 1.3 percent to 0.9 percent during the same 6-year period. Approximately 781,000 Americans used ecstasy for the first time in 2007, which is a significant increase from the 615,000 first-time users reported in 2005. Most (61.2 percent) of these new users were 18 or older; and among past-year initiates aged 12 to 49, the average age at initiation in 2007 was 20.2 years.
