How to do a Mandelin Drug Test

This entry is part 5 of 8 in the series Psychoactive Self-sufficiency

Mandelin drug test reagent

Mandelin reagent is primarily used as a simple spot-test to presumptively identify the presence of ketamine and the often-deadly PMA and PMMA. It can also be used to detect various amphetamines, 2-C’s, opiates, cocaine, and other substances. A drop or two of Mandelin (which is initially bright yellow) is added to a small amount of the test substance, and the resulting colour change and its duration compared to a reference chart of known colour reactions. Different compounds produce different colour reactions.

Performing a Marquis Drug Test

Mandelin reagent is a mix of sulfuric acid and ammonium vanadate, and therefore highly toxic, and strongly corrosive. Mandelin can be absorbed through the skin, and should only be stored in glass or porcelain containers.

  1. Shake the Mandelin well.
  2. Put a drop of reagent on a glass or porcelain surface.
  3. Take a small sample of the substance and add it to the reagent.
  4. Wait thirty seconds to one minute for the reaction to take place.
  5. Compare the resulting colour change to the references below. No colour change should be taken as a sign of the presence of one or more unknown substances.
