Molly is a man made stimulant drug that is commonly sold as MDMA/ecstasy, but what’s sold as Molly is often not pure, heightening risk of Molly overdose. Molly is often referred to as “the party drug” because it is popular at raves, concerts and festivals for its hallucinogenic and stimulant properties.

Although being a “party drug” may sound harmless, Molly is a dangerous substance. 

This page focuses on overdose warning signs and the emergency steps that are needed to prevent serious consequences and when you should seek treatment for Molly abuse.

What is Molly?

Molly (3,4-methylenedioxy-methamphetamine), otherwise known as MDMA or Ecstasy, is man made substance that can be mixed with other drugs such as cocaine, fentanyl or any other kind of powder.

These unknown impurities or additives are what make Molly dangerous. It acts as a psychedelic that produces energy, euphoria and alters one’s perception of reality.

Like other types of amphetamines, Molly increases neurotransmitter production and inhibits the absorption of norepinephrine and dopamine.

For this reason, people taking Molly have changes in sleep, appetite, mood and pain sensations. In some cases, people will experience an increase in energy, euphoria and hallucinations.

Can You Overdose on Molly?

Yes, you can overdose on Molly. The CDC reports that 60 percent of overdose deaths from 2021 to mid-2024 involved stimulants like cocaine and methamphetamine type drugs, including Molly.

Molly use can be dangerous and lead to overdose. When you take a man-made drug, you have no idea what that drug was actually made with, how it was made or where it was made.

For these reasons, the risk of overdose increases dramatically, even for experienced users.

Signs Someone May Be Overdosing on Molly

  • Anxiety or panic attacks
  • Racing heart, arrhythmia
  • Chest pains or tightness, heart attack
  • Rapid breathing or feeling like you can’t catch your breath
  • Increased blood pressure, hypertension
  • Rise in body temperature, feeling hot
  • Dehydration, skin turning grey
  • Dilated pupils
  • Dizziness, instability
  • Tremors, seizures, clenching of muscles or teeth
  • Irritability, rage
  • Confusion, or delirium 
  • Fainting or unconsciousness
  • Nausea or vomiting
  • Overheating, excessive sweating
  • Hallucinating 
  • Psychosis

If you or someone you know is experiencing any of these symptoms after taking Molly, call 911 immediately because their condition can worsen quickly.

Molly Overheating and Hyperthermia (Most Dangerous)

Molly use is popular during raves, festivals and parties. In these situations, people engage in drinking alcohol and dancing, causing the body to overheat. This can very quickly lead to severe dehydration.

Dehydration is dangerous because it can cause permanent damage to the heart and cardiovascular system, liver, kidneys and brain. 

Symptoms of dehydration include:

  • Feeling thirsty, even when drinking alcohol 
  • Headache
  • Fatigue, even while taking stimulants
  • Dizziness or lightheadedness
  • Decreased urination
  • Dry mouth
  • Increased core body temperature
  • Constipation;
  • Weakness or muscle cramps;
  • Reduced tear or sweat production;
  • Severe dehydration can lead to changes in the color of the skin

Serotonin Syndrome and Molly Overdose

Using Molly while taking a prescription antidepressant, such as SSRIs or SNRIs, can lead to a deadly surge of serotonin in the system. Molly’s euphoric effects are due in part to an increase in serotonin levels when taking the drug.

And because antidepressants block the absorption of serotonin in the brain, consuming Molly in conjunction with these medications can result in higher levels of serotonin than the central nervous system can handle.

This is a phenomenon known as serotonin syndrome.

A person experiencing serotonin syndrome must receive medical attention immediately or severe brain injury, organ damage or death may occur. 

Call someone now if you’re concerned about Serotonin Syndrome. Help is available.

What to Do if Someone is Overdosing on Molly

  • Call 911 and request medical intervention or go to the nearest emergency room immediately.
  • Try to get to a cooler environment and reduce body temperature. Don’t use ice because this can cause cooling to occur too quickly and cause additional problems.
  • Loosen clothing, give small sips of water, but not a whole glass. 
  • Be sure to share what drugs and how much alcohol have been used when speaking with emergency professionals. They need to have all of the facts to address the situation accurately. 
  • You can administer CPR if they have stopped breathing or have no pulse, or provide first aid if you know how. Remember, you are protected by Good Samaritan Laws that allow efforts to save a life. 
  • Contact family and friends who can lend support and who may have additional medical information that will assist in the treatment of the patient experiencing an overdose. 

Molly Overdose Treatment in the ER

There is no antidote for a Molly overdose.

However, once in the ER, an individual in overdose will receive supportive care, including close monitoring, especially of the heart rate and rhythm, cooling interventions, electrolyte replacement via intravenous fluids and seizure management, if necessary. 

Can You Get Addicted to Molly?

Yes, you can get addicted to Molly. Not only is Molly addictive in its own right, but because it’s common to mix Molly with opioids or other addictive substances, the risk of dependency is significant. 

Signs of Molly Addiction or Problematic Use

Signs that may indicate Molly addiction or problematic use include:

  • Using more often or taking higher amounts
  • Cravings or planning life around use
  • “Comedown” causing anxiety or depression, leading to repeated use
  • Mixing drugs more frequently
  • Continuing to use despite health, work or relationship issues

Molly Treatment Options

The first step is to ask for help. Molly addiction is treated in most inpatient and outpatient addiction treatment programs.

First, you will receive an assessment to determine what level of care is best for you. After, you will be referred to a provider who will work with you to develop an individualized treatment plan. 

Depending on your needs, your first step may be a medically supervised detox. Typically, people remain in detox for three to seven days.

Once stabilized, most people are referred to continued treatment that may include inpatient or residential treatment. In some cases, outpatient treatment, including a partial hospitalization or intensive outpatient program, may be recommended.

A comprehensive treatment plan also includes aftercare and relapse prevention support that can continue for years and is determined by your unique needs.

FAQs: Molly Overdose Questions

Can You Overdose on Molly the First Time?

Absolutely you can overdose on Molly the first time you take it. Because of the adulterants in man made pills, there is no way of knowing what exactly is in the pill being taken. It can also be difficult to determine exactly how much of the drug you are consuming, which increases the overdose risk. 

What are the Most Dangerous Molly Overdose Symptoms? 

Dehydration, overheating due to a racing heart and higher blood pressure and seizures resulting from an increased core body temperature are the most dangerous symptoms of a Molly overdose.

How Long Do Molly Overdose Symptoms Last?

Most experiences last for a few hours. However, some overdose symptoms can cause permanent damage to organs and the brain.

How Much Molly Can You Overdose On?

Because Molly is often mixed with other substances, no amount of Molly is safe. Remember, one pill can kill, so the first use can be the last. 

Can Mixing Molly and Alcohol Cause an Overdose?

Yes, alcohol can accelerate dehydration and cause overdose symptoms that complicate stabilization.

What Should You Do if Someone is Overheating after Taking Molly? 

If someone is overdosing on Molly, get them to a cooler environment, avoid using ice and only give sips of water if they are not vomiting or unconscious. Call 911 immediately. 

Can You Get Addicted to Molly?
