COCAINE Reagent Test Kit

Instruction

NOTE: Cocaine Test Kit can only test the PRESENCE, not PURITY or QUANTITY of a specific substance. Always test under a strong light and using the smallest possible sample. Never open more than 1 bottle at once, if you make a mistake you might contaminate the reagents and spoil them. If a few reactions are happening at once, only the darkest one of them will be visible.

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

BEFORE using a cocaine test kit

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

STEP ONE for testing cocaine 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 Scott reagent test (or other supplied) on the sample and wait for the results.
  • If testing cocaine with Scott whole reagent liquid should instantly turn blue, not just the sample. While many substances turn blue with Scott reagent, almost only cocaine, lidocaine and other -caines change color of the reagent liquid itself.
• Check reagent test results with instructions.

STEP TWO testing cocaine for adulterants

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.
• Next try other reagents that that should NOT change color with cocaine: 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).
• Keep in mind that various non active cuts can impact the reagent tests results (pink Marquis color change can be normal).

Next choose a purity testing kit. It enables you to detect all sample ingredients at once, however still requires reagent tests to identify substances.

• To estimate amphetamine purity (number of ingredients and their concentration) use the Substance Purity Test Kit.
• To precisly estimate MDMA purity use the MDMA Purity Test Kit, which in addition includes a calibrated plastic ruler.

AFTER using a cocaine test kit

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

FAQ

• Blue crystals. Many substances turn their crystals or powder blue with Scott reagent, but almost only cocaine, lidocaine or other caines turn the reagent liquid itself blue.
• Pink Marquis reagent color change can be normal and is thought to be caused by an unknown inactive substance.
• 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 cocaine 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 color change.
• Keep a sample to compare later in case of doubt. If control sample reacts fine, it means the reagent still works.
