How to Pass a Molly Drug Test: When Will MDMA Leave Your System?


Have you taken molly recently and are worried about testing positive for an upcoming drug test? Or maybe you just want to know when those withdrawal symptoms will go away? Either way, you’re probably wondering: how long does molly stay in your system?

We’ve got all the info you need to know how long molly stays in different parts of your body, what can affect these numbers, and how you may be able to speed to process up.


Getting Up to Speed on Molly

A bit of background info can be helpful in understanding how molly works and how it affects your body. Molly is a common street name for psychoactive drug 3,4-methylenedioxymethamphetamine (MDMA). It’s a white powder or crystal-like substance and is often taken in the form of a pill or capsule, although it can also be snorted. In recent years, molly has become a popular drug to take at parties, raves, and concerts because it can give users a “high” that makes them feel happy and full of energy.

So once you’ve taken it, how long does molly last? You can expect molly’s effects to kick in about 1.5-3 hours after you take it, and molly’s effects last roughly three to five hours. While it’s rare for molly to cause death, it is an illegal drug and can be very dangerous, causing side effects such as confusion, depression, and addiction, as well as hemorrhaging, kidney failure, and cardiac failure if you take it long-term.

Don’t drink alcohol if you take molly since it can cause you to become extremely dehydrated, which can dangerously raise your body temperature and have severe side effects, including death. Also, you should never take molly if you’re taking antidepressants since the combination can be fatal.


How Long Does Molly Stay in Your System?

Now onto the main questions: How long does molly stay in your system? When will you be able to pass an MDMA drug test?

Molly/MDMA isn’t part of the standard SAMHSA-5 drug test many people take. However, before you breathe a sigh of relief, there are two important factors to keep in mind. First, MDMA is chemically similar enough to both amphetamines and methamphetamines that it can cause positive test results for both those drugs. Also, many molly capsules are laced with other types of drugs which can cause you to test positive on a drug test, whether it’s an MDMA drug test or a standard drug test.

Exactly how long molly stays in your system depends on a number of factors, which we discuss more in the next section, but the chart below shows roughly how long you can expect molly to be detected by different types of drug tests.

Test How Long Detectable Levels Remain
Blood Up to 12 hours
Saliva 1-3 days
Urine 1-3 days
Hair Up to 3 months

As you can see from the chart, molly leaves the blood fairly quickly, within a few hours, but lasts longer in other areas, particularly the hair. Because of these variations, it’s important to know what kind of drug test you’ll be having if this is a concern for you. Urine is the most common test used to test for MDMA, and you’ll usually test clean if it has been at least three days since you took molly.

Also keep in mind that these are only estimates, and it’s difficult to get exact information since people’s bodies process drugs at different rates. In the next section we go over other factors that affect how long molly stays in your system.


What Affects How Long Molly Is In Your System?

How long does molly last in your body? There are a lot of factors that can affect how long molly stays in your system. Below are the four most important factors.


#1: How Much Molly You Take

Obviously, one of the biggest determinants of how long molly stays in your system is how much of it you take. An average capsule of molly has about 100-150mg of the drug, so if you take a significantly larger dose or multiple capsules, the molly will stay in your system longer, usually about twice as long for blood, saliva, and urine tests, and about the same length of time for hair tests.


#2: How Pure It Is

While molly is technically the term for pure MDMA, in reality molly can often be cut with other drugs, including amphetamines and stimulants. Since you likely won’t know exactly what is in the capsule you consume, it’s difficult to guess how long the exact drug you took will stay in your system.

Amphetamines last about as long in your body as pure MDMA, so their presence won’t have much of an impact, but other drugs and chemicals, such as cocaine (a common additive to MDMA capsules), could remain in your body for days longer.




#3: If You’ve Taken MDMAs Before

If you regularly take molly, your body will build up a tolerance to the drug and it will take longer for it to leave your system. Additionally, people who have built up a tolerance to a particular drug often need to take more of it to have an effect, so taking larger doses of molly will also increase the amount of time it stays in your system (see factor #1).


#4: Your Weight and Age

In general, the more molly you take in comparison to your BMI (body mass index), the slower it will be eliminated from your system, and the longer it’ll take before you get a clean drug test. This means that molly tends to stay at detectable levels in smaller people longer than people who weigh more.

Also, molly usually stays in the body of younger people for a shorter amount of time due to their generally faster and stronger immune systems and metabolism.


How Can You Get Molly Out of Your System Faster?

There are a lot of claims on the internet about things you can take or do to get drugs, including molly, out of your system faster. However, most of these claims aren’t backed up by evidence, and some suggestions are actually harmful.

You absolutely shouldn’t purchase unknown “drug flushing” products or take large amounts of vitamins or supplements that supposedly will help you get a clean drug test because you could end up doing serious damage to your health (and likely still test positive for the drug).

Two low-risk ways to potentially get molly out of your system faster are drinking water and exercising. MDMA is water-soluble so both these activities will help flush water (as well as toxins) out of your body so the molly leaves your system faster.

It’s important that you drink water and not coffee or soft drinks (and definitely not energy drinks) since they contain caffeine and will actually dehydrate you more. Also, don’t go overboard with either of these activities. Exercising until you collapse from exhaustion or chugging water until you vomit won’t cause the molly to magically leave your system immediately, instead it’ll likely just make you feel crappy. In fact, drinking massive amounts of water can actually cause serious health issues.

MDMAs can cause the body to release a hormone that prevents the production of urine, so if you’re drinking large amounts of water soon after taking molly, you can seriously interfere with your body’s salt balance and cause hyponatremia. Hyponatremia is when low salt levels in the body cause vomiting, sweating, diarrhea, and even congestive heart failure, seizures, and death. If you’re trying to stay hydrated, just drink 1-2 glasses of water an hour.

Most importantly, these suggestions aren’t a silver bullet for getting molly out of your system. At best, they can help some people get a clean test a few hours or sometimes a day faster, but, even if you follow these suggestions, you should be prepared for the possibility of testing positive if you took molly within the last three days.




Summary: How Long Does Molly Last?

Many people who take molly, a street name for the popular party drug MDMA, want to know how long molly lasts in their body, especially if they have a drug test they need to pass. While the effects of molly are strongest about 1.5-3 hours after you ingest it, the drug can stay in your system at detectable levels for roughly 1-3 days for urine, saliva, and blood MDMA drug tests, and up to three months for hair tests.

This is only a rough estimate though, since there are many factors that affect how long molly is in your system such as how much you take, how pure the molly is, if you regularly take MDMAs, and your weight and age.

There are really no surefire ways to get molly out of your system faster, although staying hydrated and exercising can sometimes speed things up a bit and potentially help you pass your molly drug test sooner.
