How to test “SPECIAL K”?

How to test ketamine: if you intend to use ketamine, first you need a ketamine test kit to check it for adulterants. Pure ketamine is white or off-white and can’t be identified by appearence. To test ketamine use reagent tests Mandelin, Mecke, Liebermann and Froehde 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.

How can I test ketamine?

BEFORE using a ketamine test kit

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

STEP ONE for testing ketamine 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 Mandelin reagent test (or other supplied) on the sample and wait for the results.
  • Check reagent test results in instructions.

How to use a ketamine test kit?

  • Check test results starting with Mandelin test kit: if testing ketamine the color change reaction should go from orange to brown.

STEP TWO testing ketamine for adulterants  

According to the EMCDDA most common ketamine adulterants are caffeine, creatine and novel dissociatives. The latter can be detected with reagents.

  • Try reagents that that should NOT change color with ketamine: Marquis, Mecke, Froehde, Robadope (for 2C-x, amphetamine, MDA or PMA), Simon’s (for cathinones, methamphetamine, MDMA or PMMA) or Zimmermann (for a-PVP and 4-MMC derivatives).
  • Liebermann reagent can also be useful – ketamine should react with a yellow color change.
  • Keep in mind that various non active cuts can impact the reagent tests results.

AFTER using a ketamine test kit

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

FAQ

  • Liquid. Evaporate the solvent before testing with reagents.
  • Fizzing. Any synthetic drug in a form of salt will bubble with most reagent tests, which are strong acids. If you see only fizzing instead of color change, that can indicate presence of a new psychoactive substance.
  • 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 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 ketamine works?

  • Test any substance and compare color reactions with instructions. It’s easiest to use vitamine C – Mandelin reagent reacts to it with a blue color change.
  • Keep a sample to compare later in case of doubt. If control sample reacts fine, it means the reagent still works.

How to 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.

HARM REDUCTION

A positive reaction does not indicate if the substance is safe. Remember to avoid mixing with other drugs, take care of yourself and take breaks. Ketamine can be habit forming and is known to cause bladder damage in those cases, therefore regular use can be particularly dangerous. Learn more at erowid.org.
