How Long Does Molly Stay In Your System?

Key Takeaways

How Long Does Molly Stay in Your System?

Like all drugs, Molly remains in your system after its initial effects wear off. Drug testing methods and detection times vary. For example:


Molly is detectable in urine tests for up to 3 days after ingestion. It takes about an hour or two for the drug to appear in urine after taking it.


After using the drug, traces of molly remain in your hair for a long time. Hair testing can detect the presence of the drug for up to 3 months after ingestion. 

It reaches hair follicles via the bloodstream and vessels that feed hair follicles. How long the drug remains in the hair is based on how fast a person’s hair grows, usually about 1 cm per month. 


Blood tests can detect traces of molly in a user’s system for up to 2 days after ingestion. After ingestion, it takes only 15 to 30 minutes to detect the presence of the drug with a blood test.


The detection window when testing saliva samples is up to 2 days after ingestion. Saliva tests are the quickest way to detect the presence of molly. This is because the drug is taken orally. It’s usually evident in saliva within 15 minutes and peaks in concentration within 1 to 3 hours after ingestion.

How Long is Molly Detectable in a Drug Test?

Molly leaves the body fairly quickly. However, traces of the drug remain for several months based on what area of the body is drug tested. For example:

  • Blood: Up to 12 hours
  • Saliva: 1 to 3 days
  • Urine: 1 to 3 days
  • Hair: Up to 3 months

Keep in mind these time frames are only estimates. People’s bodies process drugs at different rates. Your body might reveal traces of the drug for longer than these estimates.

How Long Does it Take for Molly to Wear Off? 

Although traces of the drug remain in the system for up to three months, its noticeable effects wear off much sooner. The drug’s effects peak about two hours after ingestion. After that, you’ll notice the effects of the drug gradually decreasing.

Molly's half-life is about 8 hours, meaning half of the drug would have left your system by that point. After 40 hours, about 95 percent of the drug would have left your system.

What is Molly (MDMA)?

3,4-methylenedioxymethamphetamine, or molly, is a mood and perception-altering synthetic illicit drug. Molly is chemically similar to hallucinogenic and stimulant drugs that produce the following effects:

  • Boosts of energy
  • Feelings of pleasure
  • Perception distortion

Molly is best known as a “rave” or “club” drug originally used to stay up all night to party. The drug’s popularity has increased over the years. Today, MDMA and ecstasy use can occur among people in various circumstances.

How to Get Molly Out of Your System 

There’s no way to metabolize molly faster. It must naturally make its way through and out of a person’s system according to how fast their liver breaks it down.  

You might feel better after drinking lots of water or exercising after using molly. But the drug won't leave your body any faster.

However, exercising might exacerbate dehydration. This can put your heart at risk. You could also drink too much water, leading to hyponatremia, otherwise known as water toxicity.

Symptoms of Molly Addiction

Anyone can develop an addiction to molly. Molly activates neurotransmitters in the brain that are the same as those triggered when taking other addictive drugs.

One of the most concerning effects of MDMA is the risk of developing a tolerance to the drug. This means you must take larger doses to achieve the same effects. 

Signs of molly addiction include:

  • Spending a lot of time trying to obtain the drug
  • Experiencing withdrawal symptoms when not using the drug
  • Neglecting responsibilities and obligations to use the drug
  • Taking a higher dose of the drug than intended
  • Spending increasing amounts of time recovering from molly
  • Neglecting important relationships in favor of relationships with those who also use molly
  • Breaking the law or betraying the trust of loved ones to get money to buy the drug

Risks of Molly Addiction

Over time, people addicted to molly can experience:

  • Memory loss
  • Depression
  • Problems with reasoning and attention
  • Learning problems
  • Sleep disruptions
  • Chronic confusion and disorientation

Molly Withdrawal Symptoms

Short-term users might be able to go "cold turkey" and get sober from molly without medical assistance. However, if you've been using molly for a long period, consider talking to a healthcare professional before stopping.

You can experience severe withdrawal symptoms if you suddenly stop taking molly. Molly withdrawal symptoms include:

  • Appetite loss
  • Anxiety
  • Depression
  • Focus problems
  • Fatigue

Treatment Options for Molly Addiction 

Addiction therapies are the safest way to detox from molly. However, you should still reach out to a healthcare professional for treatment options that best suit your needs. You will also need support for any co-occurring conditions.

Available treatment options for molly addiction include:

How to Determine The Best Treatment Program For You

People addicted to molly are often young. So family counseling is one of the most important factors in successful treatment. It can also teach families how to make recovery and sober living easier for their loved ones. 

The best treatment programs for substance use offer:

  • Structured routine and environment without temptation
  • Support and guidance, including information about nutrition and physical fitness, to help people develop a healthy lifestyle
  • Education regarding the negative aspects of drug use
  • Peer support from others who are recovering
  • Guidance from mental health professionals
  • Alternatives to a social environment away from people involved in drug use
