How to test METHAMPHETAMINE?

How to test methamphetamine (meth): reduce risk by using a methamphetamine test kit to check it for adulterants. Pure methamphetamine usually looks white but can’t be identified by appearence. To test meth use reagent tests MarquisMecke, Simon’s and Robadope in single-use or multiple-use test kits. Reagent tests are simple chemicals that indicate presence of a substance by reacting with different color change to different substances. To test you need just 1 drop of a reagent and a small sample, about this big -> To detect all ingredients and estimate potency it’s required to use an additional methamphetamine purity test kitTo detect fentanyl or test for fentanyl analogs use the fentanyl test strips.

Reagents presumptively indicate PRESENCE, but not PURITY or QUANTITY. Use different reagent tests to improve accuracy and to detect adulterants – 90% of adulterants will react with 1 out of 3 tests, and 95% with 1 out of 5. To detect all ingredients and estimate potency it’s required to use an additional purity test kitA positive or negative test result does not indicate if the substance is safe. No substance is 100% safe.

How can I test methamphetamine?

Short instructions:

BEFORE using a methamphetamine test kit
  • it’s RECOMMENDED to record the reaction to compare later.
  • if testing a pill, crush it finely and proceed testing using the powder
Methamphetamine testing instructions
  • Take a (small) piece of your powder/pill, about this big -> ●.
  • 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 below.
  • Consider using the TLC Methamphetamine Purity Test Kit to double check possible adulterants and estimate potency.
AFTER using a methamphetamine test kit
  • OPTIONAL: Pour baking soda over a finished reaction to neutralize used reagents.
  • Wash testing surface under running water.

STEP ONE How to identify methamphetamine?

What test kit do I need to test methamphetamine?

SAMPLE RECOMMENDED METH TEST KITS
Meth

Reagents can be divided into primary and secondary. Primary reagents react with the expected substance while secondary produce a vibrant color change with an adulterant. Here are a few key notes:

  • Marquis – primary test for most powders, secondary test for cocaine, ketamine, mephedrone and blotters
  • Mecke – primary test for most powders, secondary test for cocaine, ketamine, mephedrone; short shelf life
  • Simon’s – main test for for secondary amines, e.g. MDMA, meth, mephedrone, methylone or PMMA
  • Robadope – main test for for primary amines, e.g. MDA, amphetamine or PMA

Marquis reagent is the main test for meth/amphetamine and produces a strong orange color change which fades to dark brown. Mecke reagent is the follow up primary test to confirm the presence of meth over amphetamine. Simon’s and Robadope are useful both to confirm meth/amphetamine as well as detect primary amines (2C-x, amphetamine, MDA, PMA) in  secondary amines (meth, MDMA, PMMA, mephedrone derrivatives).

How to use the methamphetamine test kit?
  • Check test results with Marquis test kit: if testing meth/amphetamine the color of the reaction should be orange. It can look brownish after 1-2 minutes.
  • Check test results with Mecke test kit: if testing methamphetamine you should see a pale yellow color change.
  • To confirm methamphetamine follow up with the Simon’s test. To confirm amphetamine follow up with the Robadope reagent
  • Test as small sample as possible and only try more if you are not getting a conclusive result.

STEP TWO How to test methamphetamine purity?

According to the EMCDDA and drugsdata.org amphetamines are usually adulterated with caffeine and creatine, however sometimes samples also contain potent new psychoactive substances with unknown risk profiles.

Try secondary reagents. Secondary reagents produce a vibrant color change with an adulterant, but not with the expected substance.

Secondary reagent tests for meth/amphetamine:
  • Froehde reagent does not react with meth/amphetamine, but does with most powders
  • Robadope reagent can confirm primary amines (MDA, 2C-x, amphetamine or PMA)
  • Simon’s reagent can confirm secondary amines (MDMA, meth, x-MMC, or PMMA)
  • Zimmermann reagent can detect secondary (4-MMC derrivatives) and tertiary (a-PVP analogs) cathinones

Next choose a purity testing kit. It enables you to separate sample into different substances and estimate quantity, however still requires reagent tests to identify detected substances. To discover all adulterants and quantity pair reagents with a TLC (Thin Layer Chromatography) Purity Test Kit. Purity tests alone don’t identify substances and are best paired with 1-2 reagent tests.

TLC Purity Tests:
  • Qualitative: One spot indicates a pure substance. TLC test works by separating substances present in a sample in order to reagent test them individually.  You can also use an already confirmed sample for reference – if both compounds show up at the same height on the TLC “card” that indicates they are the same substance.
  • Semi-quantitative: TLC also helps estimate quantity (potency). The bigger the size of the detected spot, the bigger the amount of measured substance. Note that different substances need different calibrated rulers.

  • To estimate methamphetamine 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.

FENTANYL How to identify fentanyl?

What is fentanyl?

Fentanyl is an extremely potent and dangerous synthetic opioid, often mixed in street drugs and deadly.

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. One part of a baggie can be fentanyl free, and another lethal.
fentstrips
How to test fentanyl powder / pills / spice with a fentanyl test strip?
  • 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.
  • 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!
