About this test

The NarcoCheck^® K2 rapid test strip is an immunoassay for fast the detection in human urine of synthetic cannabis of type "K2".

K2 is a class of substances that includes molecules such as JWH, AM, and CP, which were widely known under the name “Spice”.

K2-class molecules are now much less common on the market and in seizures than K3-class substances, but they are still present.

Synthetic cannabis is an artificial chemical substance that has nothing to do with natural cannabis. It is called “cannabis” because it acts on the same receptors in the body—the CB1 and CB2 receptors—but its chemical composition is entirely different. It therefore requires a specific screening test.

Regardless of the name used—synthetic cannabis, spice, K2, or “herbal incense” in English-speaking countries—these substances are now completely illegal and classified as narcotics.

Quick and easy to use

FAQ

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

There are 3 types of synthetic cannabis:

K2 was the first class of synthetic cannabinoids to appear. Known as “Spice,” it enjoyed immense popularity between 2008 and 2012, largely due to molecules such as JWH-018, JWH-073, AM-2201, and CP 47,497. It is still found today, but in much smaller quantities compared to K3.
It is this form of synthetic cannabinoids that this test detects.
K3 emerged in the early 2010s and saw a sharp rise in popularity between 2013 and 2016. Since then, its popularity has continued to grow, and K3 now accounts for the vast majority of the market and of synthetic cannabinoid seizures. The K3 class includes all molecules of the Pinaca, Fubinaca, Butinaca, etc.
There is a specific NarcoCheck urine test for K3 (AB-Pinaca).
K4 refers to UR-144, a synthetic cannabinoid that appeared in 2011–2012. It enjoyed immense popularity until 2015. Since then, it has largely been replaced by K3. It is rarely found today.
There is a specific NarcoCheck urine test for K4 (UR-144).
