Does DMT Show Up On A Drug Test

Yes, the presence of the DMT can be detected in urine, saliva, and hair drug tests. DMT, or N,N-Dimethyltryptamine, is a hallucinogenic tryptamine drug that is naturally found in some plants. Trace amounts can also be found in human cerebrospinal fluid and other human tissue. 

Despite this, DMT is considered an illegal drug with no accepted medical applications in the United States. The Drug Enforcement Agency (DEA) classifies DMT as a Schedule I drug, under the same category as more common drugs like ecstasy and heroin.

In this article, we’ll answer questions about the effects of DMT, how long it stays in your body, which drug tests can detect DMT, and how can you effectively prevent detection from happening.

How Long Does DMT Stay In Your System?

People who take DMT report that the hallucinogenic effects of the drug begin almost instantly and end within a couple of minutes. The length of the high depends on the size of the dose and the method of consumption. When smoked freebase or vape through a vaporizer, the effects of DMT may last 30 to 45 minutes. If you drink ayahuasca tea, the effects of DMT can last up to 4 hours.

The side effects of taking DMT include increased blood pressure and heart rate, anxiety, and confusion – all of which can last up to two days. Prolonged heavy drug use may lead to long-term side effects such as cardiovascular damage due to elevated heart rate and blood pressure.

So, considering that the hallucinogenic effects don’t last very long, how long does DMT stay in your system?

DMT is metabolized fairly quickly by the body compared to other drugs. Even so, there is still a chance that trace amounts of the substance to be detected for up to 3 months. Other factors like dosage, frequency of use, and metabolism all come into play.

Even if DMT is metabolized quickly, you could still test positive because some tests do not look for traces of the drug itself. They instead search for the byproducts produced by the body to break down the substance.

Which Drug Tests Can Detect DMT?

Three of the four most common types of tests can detect the presence of DMT: hair, urine, and saliva. Tests using hair follicles can show use of most drugs, including DMT, for up to 90 days. DMT remains detectable by hair tests for 3 months even for people who have only smoked or ingested it once.

Urine tests have a smaller window of detection. DMT will show up in urine tests for 24 hours if smoked. If ingested, a urine test will detect metabolites for approximately 24 hours after use.

Though it has a very small window of detection, saliva tests can still detect DMT for about an hour after drug use. A run-in with law enforcement after consumption (such as for random roadside testing) can lead to you having to submit a saliva sample and testing positive for the substance.

As for blood testing, there is currently not enough data to determine whether DMT can be detected in blood. It is likely that DMT is metabolized so quickly that it does not last long enough to appear in blood tests.

How To Pass Drug Test For DMT

While DMT is not tested in standard drug screenings, it’s still possible. Testers use different types of equipment, and you never know if the particular one used to test your sample can detect the presence of N,N-Dimethyltryptamine. If you’re scheduled for a screening or are anticipating random testing, here are the ways to get a clean result for each type of test:

Hair Test

Because hair follicles tend to have a broader detection window, detoxing hair is important even if it’s been weeks since you last used any illegal substance. Old Style Aloe Toxin Rid Shampoo is a crucial part of the Macujo method, which was created specifically to remove traces of THC (cannabis) from hair follicles. This powerful clarifying shampoo also comes in handy after smoking or ingesting DMT.

Urine Test

Synthetic urine is the go-to solution for people who need to take a urine test. Your best bet to pull this off is by using Clear Choice Sub Solution, which contains all of the chemical markers that testers look for to ensure validity of the sample. Unlike other synthetic urine, it does not contain the chemical Biocide that is used to lengthen the synthetic urine’s shelf life. Biocide, if detected, will alert testers that the sample is not legitimate.

Detoxing is an alternative for people who are uncomfortable with faking their urine and would rather go down the natural route. Toxin Rid 10-Day Detox is a program that ranges from 1 to 10 days (depending on your level of exposure), and uses herbs, vitamins, and natural minerals to speed up the body’s detoxification.

Saliva Test

A product called Toxin Rid Rescue Wash will come in handy to cleanse the mouth of metabolites. This mouthwash is meant to be used just before a sample is taken, as it only works for a short period of time.

Toxin Rid Rescue Wash comes in a small 1-oz bottle. This makes it convenient to have and use in case you’re surprised with a random drug testing.

DMT’s Schedule 1 classification means getting caught has legal consequences such as fines and incarceration. When it comes to using illegal substances, it’s best to err on the side of caution. Keep the products mentioned above at hand at all times so you’re never caught off-guard when you’re suddenly scheduled for a drug screening.
