MDMA Overdose: Understanding the Risks

The popularity of drugs like MDMA stems from the euphoria they produce in social environments like parties, raves, nightclubs, and concerts. Yet despite its reputation as a party drug, MDMA can be extremely dangerous when misused.

One of the reasons MDMA poses significant overdose risk is because it is often mixed or “cut” with other illicit substances. Understanding the signs associated with MDMA overdose as well as knowing how to respond to emergency situations associated with an MDMA overdose could save a life.

What Is MDMA?

MDMA, also referred to as ecstasy, XTC, or molly, is a synthetic psychoactive substance that changes mood and energy level and alters a person’s perceptions.[1] Its initials, MDMA, stand for 3,4-methylenedioxymethamphetamine, the active ingredient in the substance, and the term “molly” comes from “molecular MDMA.”

MDMA is usually sold as tablets, capsules, crystals, or powder.

Many people do not realize that the drug called molly does not mean that it is pure MDMA; in fact, according to research conducted by the Drug Enforcement Administration, products that are sold as molly frequently contain significant levels of other stimulants or synthetic drugs. [2] Common examples of other substances that can be added to MDMA are methamphetamine, fentanyl, synthetic cathinones (bath salts), or other unknown substances.

Once ingested, MDMA affects the central nervous system (CNS) by generating a rush of serotonin, dopamine, and norepinephrine, creating a temporarily increased amount of both energy and warm emotions, but it can also cause extreme strain on the heart and have a negative effect on the body’s ability to regulate temperature.

Can You Overdose on MDMA?

Yes, an overdose from MDMA is highly possible and can occur very quickly. Many falsely believe that ecstasy has a lower probability of overdose than other drugs since ecstasy overdose does not occur as frequently as overdoses from other substances like opioids or meth.

According to data provided by the Substance Abuse and Mental Health Services Administration, the majority of emergency department visits for MDMA also include alcohol or a combination of multiple drugs, which increase the chances of overdose.[3]

The potential to overdose on MDMA is influenced heavily by the individual’s use of MDMA and by a combination of the following variables:

• Dose strength
• Purity of the drug
• Individual body chemistry
• Pre-existing health issues
• The temperature of the environment
• Combining it with other drugs, including alcohol

A dose that one person survives may overwhelm another person’s body. Even pills that have the same physical appearance may not have the same amount of MDMA in them.

How Much MDMA is Dangerous?

Recreational MDMA doses can vary widely, and tablets sold as MDMA, molly, or ecstasy may have significantly different amounts of the drug or other substances in them. Reported tablet doses have ranged from about 50 mg to 150 mg, and severe toxicity can occur with any use, especially at higher doses, with repeated dosing, or when MDMA is combined with high environmental heat, dehydration, or other substances like alcohol, antidepressants, opioids, or stimulants.[4]

What Factors Increase the Risk of an MDMA Overdose?

Risk factors that significantly increase the chances of having an overdose or an extremely negative reaction include:

• Unknown Purity & Contaminants: Illegal street drugs are often adulterated or made with multiple substances, causing the user to experience adverse effects. Some pills sold as ecstasy may contain additional illicit substances.
• Large Doses and Repeated Use: Some recreational drug users use MDMA by “stacking” or “piggybacking,” meaning they take additional doses before the previous doses wear off, to keep their high longer, which increases the potential to overdose.
• Using Multiple Drugs: Using MDMA in combination with a selective serotonin reuptake inhibitor (SSRI) or monoamine oxidase inhibitor (MAOI), both of which are antidepressants, will greatly increase the potential to develop serotonin syndrome as well as an overdose. Any additional drugs of any kind increase the risk of an overdose.
• Hot Environments & Dehydration: Most MDMA overdoses occur in crowded places where people have been dancing for long periods of time without cooling down or staying hydrated.
• Pre-existing Health Conditions: Heart conditions, liver problems, kidney disease, or some mental Health disorders may contribute to overdose.

Signs and Symptoms of an Overdose from MDMA

Recognizing the early signs of an MDMA overdose and taking appropriate action significantly increase the likelihood of survival.[5]

Early Signs of MDMA Overdose

Symptoms of elevated MDMA toxicity or an impending overdose can include:

• Hyperthermia and Excessive Sweating: Hyperthermia, which is a dangerously elevated body temperature, is common, and the person’s skin may feel hot to the touch; they may sweat profusely or stop sweating.
• Signs of Cardiovascular Problems: Signs associated with MDMA overdose may include rapid heart rate, disturbances with heart rhythm or heart palpitations, chest pain, elevated blood pressure, and breathing difficulties.
• Signs Related to Neurological or Psychological Problems: After an MDMA overdose, a patient may have agitation, panic, anxiety, confusion, paranoia, tremors, and a clenched jaw.
• Signs Related to Gastrointestinal Problems: Gastrointestinal symptoms of an MDMA overdose can include nausea, vomiting, and abdominal pain.
• Fainting or Loss of Consciousness: Signs of worsening MDMA toxicity can be loss of consciousness or sudden collapse.

Severe or Life-Threatening Signs and Symptoms of an MDMA Overdose

If an MDMA overdose is occurring, these life-threatening symptoms may occur:

• Seizures or rigid muscles: Experiencing rigidity, seizures, or convulsions can occur when there is severe MDMA toxicity affecting the nervous system.
• Extremely elevated body temperature (hyperthermia): Severe overheating can result in significant injury or damage to the muscles called rhabdomyolysis, which is a breakdown of muscle tissue that can severely damage the kidneys.
• Cardiovascular collapse: Extreme strain on the heart can potentially result in abnormal heart rhythms, heart attack, and dangerously high blood pressure.
• Respiratory Distress: The body’s inability to get enough oxygen when breathing becomes shallow, slow, or ineffective.
• Kidney / Liver Failure: Symptoms of kidney or liver damage include decreased urine production or urine that’s darker in color.

Understanding Serotonin Syndrome MDMA Risks

An MDMA overdose can potentially trigger an extreme level of serotonin presence in the nervous system, resulting in serotonin syndrome, in which serotonin levels increase dramatically due to the large amount of serotonin released into the brain and body, especially when combining MDMA with other antidepressants or serotonergic substances.[6]

Some symptoms of serotonin syndrome include:

• Marked increase in body temperature
• Muscle tremors, rigid muscles, overactive reflexes
• Agitation, disorientation or confusion
• Unconsciousness
• Seizures

Organ failure, cardiac complications, or death can occur without immediate treatment.

What to Do During an MDMA Overdose

• If you suspect someone has overdosed on any drug, immediately call 911. Most states have Good Samaritan laws that help protect people who seek emergency medical attention on someone’s behalf during an overdose or medical emergency.
• If the person is unconscious, administer naloxone. The drug they took might have been adulterated with fentanyl or some other opioid.
• Keep the person as comfortable as possible until medical professionals arrive. Find a cool and quiet location, remove excess clothing, apply cool cloths or ice packs to their neck and armpits, continuously monitor their breathing and pulse, and remain with the person at all times until professional medical personnel arrive.
• Avoid giving water in large amounts. Even though treating dehydration is important, giving excessive amounts will create a secondary risk of hyponatremia, which is dangerously low sodium, which could lead to seizures or brain swelling.

There is no home remedy or medical antidote for an MDMA overdose.

Long-Term Effects of MDMA Use

Over time, many physical and psychological complications may develop from repeated MDMA use. Chronic users may experience

• Chronic fatigue
• Anxiety
• Memory issues
• Difficulty concentrating
• Sleep disturbances
• Depression

According to some studies, repeated use can also result in serotonin depletion and cognitive impairments related to thinking, memory, and comprehension. With long-term use, physical complications can include liver damage, kidney injury, muscle pain, and cardiovascular problems.[7]

Prevention and Harm Reduction

The only way to prevent overdose or other complications associated with MDMA use is to not use MDMA.
