Reagent Chart

Written by on February 9, 2020

Reagent testing is a simple way to test a substance and observe a chemical reaction that will give you a better idea of what the substance is.

It is by no means a perfect method, with many pitfalls. But in a market where information is seriously lacking, it can at least held to point someone in the right direction.

Reagents are chemicals that react with a small sample of the drug being tested by changing colour. The most well known reagents are marquismandelin and mecke. The colour change indicates what might be in the drug (which you can check on a chart that comes with the kit). The kits can be legally sold and purchased as a single use test, and makers report sales have increased by 110% in the past year.

Here is the latest reagent colour chart, with some notes on this update:

  • LSD colour reactions drastically changed to match GC-MS verifed samples videos by Reagent Base & Energy Control
  • Single Generic Opiates section removed (due to inaccuracies).
  • Added a single opiate entry for Heroin. Verified by 3 different samples tested.
  • Changes to some of the different 2C-x colour reactions to match GC-MS verifed samples videos by Reagent Base & Energy Control
  • Removed dead links previously provided by BunkLeaks & BunkPolice video database of GC-MS verifed samples videos by Reagent Base & Energy Control
  • Added link to YouTube channel by Acinad Romanoff who has been kind enough to re-upload many of the now missing BunkLeaks & BunkPolice Reaction Video Database
  • Other minor updates in descriptions etc.
  • Last note on safety if using only Mandelin & Mecke in the field (with the 2 Colour Chart Sheet) that the reactions for PMA, PMMA and Heroin are almost identical. Marquis is suitable as an additional test to distinguish between Heroin and PMA/PMMA.

The critical part of any harm reduction initiative is the engagement it creates between consumer and reliable information about potential harms, side effects etc.

When also accompanied by excellent harm-reduction literature, some of the risks associated with reagent testing are mitigated. If a consumer has knowledge of the limitations of the test, it may still be of some use. Reagent testing would struggle to identify very high purity MDMA (more than 200mg in a tablet, which could be fatal, was seen in Europe this year) and novel psychoactive substances.
