This strip is made for the detection in human urine of “K2” (or “Spice“) type of synthetic cannabinoids (synthetic cannabis).

The synthetic cannabis is a completely artificial substance and has nothing to do with the usual cannabis/marijuana. Their only common point is to activate the same receptors in the human body (CB1 and CB2 receptors). That said, the molecules of synthetic cannabis and “natural” cannabis are very different. This is why it is necessary to use a very specific test to detect any use or abuse of this new drug, hence the usefulness of this K2 / Spice urine test.

K2 is the first generation of synthetic cannabinoids to appear on the market in the mid-2000’s. This drug is still abused, but it is important to notice that a second generation of synthetic cannabinoids has now arrived, named K2 or AB-Pinaca.

This test is a qualitative assay (type “NO / YES”), and thus delivers a “NEGATIVE” or “POSITIVE” result.

More info

The NarcoCheck ® K2 rapid test strip is an immunoassay for fast the detection in human urine of synthetic cannabis of type “K2”. This synthetic cannabis is now also known as SPICE.

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.

Whatever the name used, synthetic cannabis, spice, K2, or “herbal incense”, these substances are now totally illegal and classified as narcotics.

There are 3 types of synthetic cannabis:

    The K2, or Spice, which appeared in the mid-2000s.
    It is this form of synthetic cannabinoids that this test detects.
    K2 is still widely found in various seizures made around the world. Over time K2 has taken the form of various groups of molecules, such as AM, HU, JWH, CP etc.

The K3, a new generation of synthetic cannabinoids, which has been increasingly found on the market since 2014-2015.
There is a specific NarcoCheck urine test for K3 (AB-Pinaca)

This strip detects the consumption of synthetic cannabis (type K2) up to 48 hours after use! Fast and easy to use. Made in France. Shipping in 24h worldwide.
