Testing Questions

What color reaction should I expect when testing?

For the most up-to-date color reaction results, see our drug testing results page.

How do I do a test?

Instructions on performing the test is included with your test kit. We’ve also included them on the product pages:

What if my sample contains a mix of more than one substance?

If the testing liquid reacts with the substances separately, it will react with them together as well.

For example, if your sample contains Ecstasy (MDMA) mixed with Speed (amphetamine), both will react simultaneously resulting in a muddy color with the Marquis Test. With Ecstasy alone, you’d expect a purple/black color.

Reaction of one drug can be much darker and more intense than another. If this is the case, it can be difficult or impossible to see the reaction of the second drug. This is a limitation of colorimetric testing.

How much of the sample should I use?

A very small sample is sufficient. In general, your sample should be about this size: ( ● )

Unless otherwise indicated, use the following guidelines:
Pill: Scrape off about 5% of the pill.
Powder: Use a few grains, about the size of a pinhead.
Paper: Cut off a small corner.
Liquid: Place a couple of drops on a small piece of uncoated paper.

How much testing liquid should I use on my sample?

One or two drops of the reagent is enough.

How reliable are the tests?

While reagent testing is the best method for on-the-spot testing, it is never 100% conclusive. There are many variables that can impact what the reaction looks like. Lighting, impurities, and unwanted substances in your sample may all play a role.

What’s that powdery substance or pink stuff inside the container that came with my kit?

There’ll either be a powdery substance or a pink fluffy material in the white jar you receive. Both are absorbent materials. In the off-chance that there’s a spill during transport, it prevents the reagent from doing any damage to its surroundings. We include it as an extra precaution. You can also conduct your tests over the jar so that if a drop misses the testing vial, the reagent will land onto the absorbent material.

How long does the testing liquid last before it expires?

Our reagents come in durable glass bottles. The testing liquid will last a long time (over 4 years) if you store it appropriately. They will expire very quickly if you keep them in warm place or in the sun.


  • Store reagents at a cool temperature. A freezer is ideal. If that’s not possible, try storing at a consistent temperature in the range of 2°–22°C (36°–72°F).
  • Store the bottle upright.
  • Keep out of prolonged direct sunlight.
  • Replace caps immediately and tighten them carefully so that exposure to air and humidity is limited.
  • If you have more than one reagent, avoid switching bottle caps!

Our tests that come in glass ampoules (e.g. purity tests) should be stored at room temperature and are guaranteed for 3 years.

Are your test kits legal?

Yes. Our test kits do not contain any controlled substances or materials.
