How to test DMT?

How to test DMT: if you intend to use DMT, first you need a DMT test kit to check it for adulterants. Pure DMT can look white, brown or tan, and can’t be identified by appearence. To test DMT use reagent tests Ehrlich, Hofmann, Marquis and Mecke in single-use or multiple-use test kits. To detect fentanyl or test for fentanyl analogs it’s recommended to use fentanyl test strips.

Drug tests presumptively indicate PRESENCE, but not PURITY or QUANTITY. Use different tests to improve accuracy and to detect adulterants – 90% of adulterants will react with 1 out of 3 reagents, and 95% with 1 out of 5.

A positive or negative test result does not indicate if the substance is safe. No substance is 100% safe.


TL;DR: Here is an image with a quick cheat sheet how to use the DMT test kit, or check out more detailed guide on how to test DMT further below.

How can I test DMT?

BEFORE using a DMT test kit

  • It’s RECOMMENDED to record the reaction to compare later

STEP ONE for testing DMT powder / crystals

  • Take and finely crush a small piece, no bigger than a head of a needle – like this •.
  • Put it on a suitable testing plate, preferably a spot test plate or the bottom/underside of a ceramic mug (example). *If using single-use vials insert the sample and observe, as the reagent is already within.
  • Add one (or two) drops of an Ehrlich reagent test (or other supplied) on the sample and wait for the results.
  • Check reagent test results in instructions.

How to use a DMT test kit?

  • Check test results with Ehrlich test kit: if testing DMT the exact color of the reaction is not important – the test is of a yes/no type. It will go purple or pink if it is exposed to an indole compound like DMT, an analogue like 5-MeO-DMT or any other tryptamine.
  • NBOMe compounds and other phenethylamines (like 2C-B) will not give a colour change with the Ehrlich reagent.

STEP TWO testing DMT for adulterants  

25I-NBOMe (responsible for many deaths) and other new synthetic phenetylamines do not react with Ehrlich and Hofmann reagents, unlike DMT and other tryptamines. 5-MeO-DMT, which is about 5 times more potent than DMT, can be disntguished with the Hofmann test.

  • False positives. To check if Ehrlich test result could be a false positive, use Hofmann reagent to test more specifically for DMT and tell it apart from other indoles. It’s more precise than Ehrlich, but reacts slower.
  • Marquis test should change color yellow > orange > brown.
  • Mecke test should change color from yellow to green.
LSD test false positive with 5-HTP or 5-MeO-DMT
How to test DMT? Testing DMT using Ehrlich and Hofmann reagents included in the DMT Test Kit. All indoles turn Ehrlich pink, but DMT should NOT turn quickly green in Hofmann test. The same kit is recomended for decting NBOMes and testing LSD.

AFTER using a DMT test kit

  • OPTIONAL: Pour baking soda over a finished reaction to neutralize used reagents.
  • Wash testing surface under running water.

FAQ

  • Plants. Reagents are not suitable for testing plant material, nontheless you might have some success with Ehrlich test.
  • Liquids. Reagents are not suitable for testing mixtures like ayahuasca. If you suspect you have liquid synthetic DMT, evaporate the solvent before testing.
  • False positives. To check if Ehrlich test result could be a false positive, use Hofmann reagent to test more specifically for DMT and tell it apart from other indoles. It’s more precise than Ehrlich, but reacts slower.
  • Speed of the reaction does not indicate quantity nor purity. However, if you are having trouble interpreting your result try using a bigger sample.
  • How many tests can you get from one test kit? A multiple-use test kit lasts up to 100 (5 ml) or 200 (10 ml) tests. Each drop equals one test. A single use-test kit contains 2 disposable ampoules (2 tests).

How to check if reagent for testing DMT works?

  • Test any substance and compare color reactions with instructions. It’s easiest to use 5-HTP or melatonin with Ehrlich reagent, which should turn pink / purple or blue.
  • Keep a sample to compare later in case of doubt. If control sample reacts fine, it means the reagent still works.

How can I detect fentanyl?

BEFORE using a fentanyl test strip

  • It’s RECOMMENDED to test each and every dose. Because of extreme potency (microgram range) fentanyl is never evenly mixed in.

STEP ONE for testing fentanyl powder / pills / spice

  • Dissolve 100-200 mg in at least 125 ml of water (half a cup).
  • Grab a test strip by blue end and insert it into the liquid, no higher than the blue line.
  • Wait until liquid starts visibly moving up the test strip (up to 15 seconds).
  • Put the test strip away on a flat dry surface and read the result in 2 minutes.

How to use a fentanyl test strip?

  • Check test strip results: a single line confirms the presence of fentanyl, while two lines (even faint) rule it out.

Fentanyl test did not react as indicated? Watch out!
All test results are available in our instructions and TestDrugs apps.

FAQ

  • Faint line. Even faint second line result is enough to rule out the presence of fentanyl.
  • Injecting. If you inject you especially need to test each and every dose. It’s best to test the spoon (or cooker) residue every time before use.
  • Speed of the reaction does not indicate quantity nor purity. However, if you are having trouble interpreting your result try using a bigger sample or crushing it better before testing.
  • How many tests can you get from one test kit? A single fentanyl test strip is enough for one test.
