Simon’s is a secondary test that tells the difference between MDMA and MDA, and so is the second step in our MDMA kit. It can also differentiate between methamphetamine and regular amphetamine. Simon’s reagent should never be used alone. It should only be used after first testing your sample with Marquis reagent. Two bottles (A and B). Contains enough reagent for 50-75 tests.


Reagents are chemicals that change color when they come into contact with certain drugs, enabling you to detect their presence in a sample. Reagents cannot, however, detect every drug, nor can they tell you how pure or potent your drugs are. Even if you get the expected color reactions for the drug you want, there could still be one or more other drugs present. This is because:

  • Not all drugs change color with reagents.
  • Darker colors may overshadow lighter colors.
  • A very tiny quantity of a drug may not produce a visible color change.

Despite these limitations, reagent testing is useful for identifying the presence of specific drugs, and——most importantly——for determining whether your sample does not contain the drug you want.


  • Detect the presence of certain drugs
  • Inform your decision about whether or not to consume a drug


  • Tell you how potent your drugs are
  • Tell you if your drugs are pure



1 Place a tiny amount of your drug onto a white, ceramic plate. Make it about the size of a pinhead. We will refer to this as the “sample” of your drug. For pressed pills, use a sharp knife to scrape the powder off the side. For blotter paper, cut off a tiny piece of the corner. For liquid drugs, place one drop onto the plate.

2 Carefully place one drop of reagent onto the sample. Do not let the bottle touch the sample or you will contaminate the entire bottle of reagent. If you are using a 2-bottle reagent such as Simon’s, Folin, or Morris, place one drop from bottle A and then one drop from bottle B onto the same sample.

3 Observe the color change and compare with the enclosed color chart. Most reagents will change color within twenty seconds.

  • Ehrlich’s reagent can take up to 5 minutes.
  • Morris reagent needs to be stirred (use a toothpick or the sharp point of a knife).

The final color will appear after stirring for a full 30 seconds.

4 Repeat. Most drugs need to be tested with more than one reagent. When using multiple reagents, put the cap back on the first reagent and repeat the process with the next reagent using a new sample from the same batch that you’re testing.

5 Clean up. Use baking soda to neutralize 5 the chemicals, then wash the plate with soap and water.


Below are reactions for some of the most commonly used drugs. For more color reactions, see this reddit page.


Keep reagents out of heat and sunlight to prolong the shelf life. If stored in a refrigerator or freezer, most reagents will last a year or longer. (Make sure to thaw them out to room temperature before use.) Dispose of unused reagents at a hazardous waste facility.

  • Mandelin reagent starts out light orange in color and turns cloudy yellow after 3-4 weeks. This is okay. Make sure to shake the bottle before each use.
  • Marquis and Mecke reagents begin as clear liquids and gradually darken over time. This is okay. They are only expired when the liquid in the bottle becomes so dark that you can no longer see the color reaction.


If contact is made with the skin, wash with water immediately. If it gets in the eyes, flood the eyes with water for at least 10 minutes, holding them open. If accidentally ingested, rinse the mouth. Do not induce vomiting. Drink water and seek immediate medical attention.
