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.
