Description

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.

Technical data

Cut-off : 25 ng/ml
This K2 / Spice test will be positive if the test sample contains at least 25 nanograms of traces of synthetic cannabis per milliliter of urine. Conversely, it will be negative if the sample contains less or not at all.

Detection time of K2/Spice in urine :

  • 2 to 3 days after consumption

NarcoCheck® Synthetic Cannabinoids test (K2 25)

compounds cut-off (ng/ml)

Synthetic Cannabinoids and Drug Testing

A Review of “Hair analysis as a tool to evaluate the prevalence of synthetic cannabinoids in different populations of drug consumers.”

by Joseph Jones, Ph.D., NRCC-TC

What are Synthetic Cannabinoids?

A few years ago, synthetic cannabinoids (syn-cans), such as K2 and Spice, exploded onto the scene as an alternative to marijuana because of the marijuana-like effects experienced following use. The first, and perhaps most popular, of the synthetic cannabinoids was the JWH and HU series of cannabimimetic compounds with over 250 different analogs. Governments have struggled to keep up with the cat-and-mouse game as distributors migrate from one compound to the next as they are banned or controlled in varying jurisdictions. Marketed as a legal high, marijuana users used these preparations as an alternative drug in order to pass drug screens since most routine drug screens do not detect many, if any, of the endless variety of compounds.

Synthetic Cannabinoids are no Game

Although perceived to be a low risk alternative to marijuana, syn-cans have been associated with several negative health consequences. These negative consequences include anxiety, tachycardia, hallucinations, violent behavior, and psychosis.1 The health effects of long term syn-can use are largely unknown. Fortunately, the use of syn-cans in the general population is still low compared to the prevalence of marijuana.2

Testing For Synthetic Cannabinoids in Hair

There are few methods in routine use for the detection of syn-cans. Salomone et al. (2013) developed a method to detect the presence of 23 common syn-cans using hair as the specimen type. Hair is a non-invasive specimen and offers a potentially long detection window for drug detection. The method was developed according to commonly accepted guidelines (ISO/IEC 17025:2005; Gruppo Tossicologi Forensi Italiani; Society of Forensic Toxicologists/American Academy of Forensic Sciences). The fully validated method was challenged by testing 344 archived authentic hair specimens that were previously tested positive for marijuana, cocaine, opiates, methadone, amphetamines, or the long term alcohol biomarker, ethyl glucuronide.

Findings

Of the 344 samples, 15 were found to contain at least one syn-can. All 15 syn-can positive specimens were also positive for another illicit drug. Twelve of the 15 samples were positive for marijuana. The other 3 samples that were negative for marijuana were positive for cocaine, heroin, or ecstasy.

Implications

This paper provides us with a couple of interesting insights to the problem of syn-cans. The prevalence of syn-can use is still low compared to other drugs of abuse so resources for detection should be distributed accordingly. Secondly, it appears that over a long period of time, such as 3 months, users of marijuana or other drugs will not maintain use of only syn-cans. It appears that users eventually revert to their drug of choice over the long haul because they find their drug of choice to be more pleasurable. This allows the hair testing laboratory to continue to focus testing on the standard illicit drugs of abuse and, for the moment, side step the cat-and-mouse game of the never ending syn-can analogs that make their way to the marketplace.
