Estimating how long DMT, a psychedelic compound, is detectable in the body depends on many variables, including which kind drug test is being used. DMT - also known as Dimethyltryptamine, businessman's trip - can be detected for a shorter time with some tests, but can be "visible" for up to three months in other tests.

The timetable for detecting DMT in the system is also dependent upon each individual's metabolism, body mass, age, hydration level, physical activity, health conditions and other factors, making it almost impossible to determine an exact time DMT will show up on a drug test.

The following is an estimated range of times, or detection windows, during which DMT can be detected by various testing methods:

How Long Does DMT Stay in the Urine?

DMT can be detected in the urine for 2-5 days

How Long Can DMT Be Detected in Blood?

No current data is available concerning blood tests for DMT.

How Long Can a Saliva Test Detect DMT?

A saliva test can detect DMT for up to 1-5 days

How Long Can a Hair Test Detect DMT?

DMT, like many other drugs, can be detected with a hair follicle drug test for up to 90 days.

How Does DMY Affect the Brain?

Because DMT is a hallucinogen users can experience unexpected side effects. Some hallucinogens can affect the action of the brain chemical serotonin, which regulates:

  • Mood
  • Sensory perception
  • Sleep
  • Hunger
  • Body temperature
  • Sexual behavior
  • Muscle control

Hallucinogens can also interfere with the action of glutamate, another brain chemical which regulates:

  • Pain perception
  • Responses to the environment
  • Emotion
  • Learning and memory

Building Up a Tolerance

Like most hallucinogens, DMT is not addictive, but users of the drug can build up a tolerance to it causing them to have to user greater amounts to achieve the same results, a dangerous practice.

Preventing an Overdose of DMT

To avoid an accidental overdose of DMT, it is necessary to know how long the drug remains in the system.

According to the National Institute on Drug Abuse, in high dosages, DMT can produce the following effects:

  • Hallucinations
  • Memory loss
  • Physical distress, including dangerous changes in blood pressure, heart rate, respiration, and body temperature
  • Marked psychological distress, including feelings of extreme panic, fear, anxiety, paranoia, invulnerability, exaggerated strength, and aggression
  • Use with high doses of alcohol or other central nervous system depressants can lead to respiratory distress or arrest, resulting in death
