MDA is a substance similar to MDMA, but acts twice as long, has more psychedelic effects and could be more neurotoxic than MDMA. It is also often found in “Ecstasy” pills, missold as MDMA.
While reagent testing works great using multiple reagents and pure samples, it doesn’t always work well for samples with cuts. The best way to detect mixed in adulterants (cuts) is to send a sample to a laboratory substance analysis service (like Energy Control). There are however also other, limited methods, that can be used in home or party settings: TLC (Thin Layer Chromatography) and reagent testing.
Reagent testing works by pouring 1-2 drops of a reagent test onto a small sample (● this much) and comparing the happening color change reaction with instructions. This method is limited by possible false positives – substances that react in a similar way. With most reagents, it can also be hard to tell if more substances are reacting at once, or just one.
To detect cuts using reagent tests make sure you know:
- What adulterant you are looking for
- What reagent reacts to a preferably dark, vibrant color with the adulterant
- Which reagent can work better at detecting the adulterant than the main ingredient
It is particularly useful to pair universal reagents, that react with 500+ substances (like Marquis, Mecke), with more selective ones, that might not react with the desired substance at all but indicate other (like Zimmermann, Scott, Simon’s or Robadope).
