About this test

The NarcoCheck® IDetect® THC is a test for the detection and identification of TetraHydroCannabinol (also known as Δ9-tetrahydrocannabinol), the main psychotropic molecule in cannabis.

It can be used in several ways:

  • To detect invisible traces of THC on surfaces and all kinds of objects.

    The sterile swab supplied in the kit is used to collect residual microscopic particles from any object, utensil or support that has been used to handle substances containing tetrahydrocannabinol (such as cannabis flowers or resin). The test then provides a clear positive or negative identification.

    It should be noted, however, that the detection capabilities of this test are necessarily less on microscopic traces than with solid samples such as plants or resins.

  • To detect the presence of THC in all types of solid samples (resins, powders, plants, etc.) and liquids (oils, concentrates, etc.)

    Simply take a few milligrams or milliliters of the substance to be tested. The test then explicitly defines whether the sample contains THC, with a positive or negative result.

Also known as THC presence test or THC contamination test, this detection kit can be used anywhere, simply and in a matter of minutes.

Quick and easy to use

How to choose between immunological and chemical tests?


(product on this page)


If your need is simply to formally identify a sample of cannabis (marijuana or hashish), then turn to chemical cannabis identification tests. They're perfectly suited to this purpose, with the added advantage of being cheaper, faster and a little simpler to perform.

If your need is for the detection of THC molecules in more or less refined products (laboratory reagents, raw materials, extractions, etc.) or products that are not supposed to contain THC, then prefer immunological tests, as they are more sensitive than chemical tests, i.e. they can detect the presence of a much smaller quantity of THC (of the order of ten nanograms, or 0.00000001 grams).

Furthermore, immunological tests are the only ones that can detect invisible micro-traces or particles of THC on surfaces or everyday objects.

The benefits of the IDetect® THC

  • Safe and easy to use.
  • Perform the test and obtain the result in a few minutes.
  • Economical and reliable.
  • Immunological test, more specific and much more sensitive than a chemical test.
  • Can be used to confirm the result of a chemical test.

In the package of the IDetect® THC

You will find:

  • Multilingual instructions for use.
  • A sterile collection swab.
  • A collection vial containing a dilution liquid.
  • A rapid test to identify THC (Δ9-tetrahydrocannabinol).

This test is a professional device used to help identify presumptive drugs or narcotics in the form of powders (fine or agglomerated), crystals, tablets, or some specific plants. It is not designed to test "anything and everything" (food, beverages, biological materials etc.), and particularly everyday products (household, gardening, cosmetics etc.) which contain various chemical compounds that can trigger unexpected reactions, and thus cause false or erroneous results.

Like any rapid test, this test delivers a purely indicative result. To know or confirm with certainty the composition of the sample, it is necessary to analyze it with a reference analytical method such as GC/MS or HPLC-MS/MS. The use of this test must therefore be done with full knowledge of the fact that no rapid screening test can be 100% reliable.
