The NarcoCheck® K3 rapid test strip is an immunoassay for fast the detection in human urine of synthetic cannabis of type "K3". This synthetic cannabis is now also known as AB-PINACA and AB-FUBINACA.

Synthetic cannabis has nothing to do with natural cannabis. It is actually an active chemical and artificial substance. It is called "cannabis" because it mimics natural cannabis by acting on the same receptors of the organism, namely the CB1 and CB2 receptors.

Its chemical composition is completely different from natural cannabis, and as such, synthetic cannabis must be screened with a test specific to it, just like any other drug.

This test will detect the two main molecules of K3, AB-PINACA and AB-FUBINACA.

What is the difference between the K2, K3 and K4 test?

There are 3 types of synthetic cannabis:

  • The K3, or AB-PINACA, is a new generation of synthetic cannabinoids, which has been on the market more and more since 2014-2015.
    It is this form of synthetic cannabis that this test detects.

  • The K2, or Spice. It was the first type of synthetic cannabis to appear in the mid-2000s. It is still widely found in various seizures made around the world.
    There is a specific NarcoCheck urine test for K2 (Spice).

  • The K4 is a third type of synthetic cannabinoids, which has been on the market since 2014-2015.
    There is a specific NarcoCheck urine test for K4 (UR-144).
