How to detect LEVAMISOLE: if you intend to use cocaine, first you need to check it using a test kit to rule out presence of levamisole, a dangerous animal deworming agent. To detect levamisole in cocaine use reagent tests Marquis and Liebermann included in the Cocaine Test Kit, or Mandelin. 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 cocaine test kit, or check out more detailed guide how to test for levamisole further below.
How can I detect levamisole?
BEFORE using a test kit
- It’s RECOMMENDED to record the reaction to compare later
STEP ONE for testing levamisole powder / capsules
- 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 Marquis reagent test (or other supplied) on the sample and wait for the results.
- Check reagent test results with instructions.
STEP TWO testing cocaine for levamisole
According to the EMCDDA most common cocaine adulterants are levamisole (animal deworming agent), caffeine, other stimulants and different pharmacuticals like phenacetin or lidocaine.
- To detect levamisole use reagent tests Marquis and Liebermann. If only Liebermann turns orange, that indicates the presence of levamisole. If Marquis is orange too, that indicates presence of meth/amphetamine.
- Keep in mind that various non active cuts can impact the reagent tests results (pink Marquis color change can be normal).
- Full informations are available in instructions and color charts, videos & apps.

AFTER using a levamisole reagent test
- OPTIONAL: Pour baking soda over a finished reaction to neutralize used reagents.
- Wash testing surface under running water.
FAQ
- Fizzing. Any synthetic drug in a form of salt will bubble with most reagent tests, which are strong acids. If you see fizzing without 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 levamisole reagent test works?
- Test any substance and compare color reactions with instructions. It’s easiest to use aspirin – Marquis reagent reacts to it with a slow pink or orange 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.
