The NarcoCheck® Saliva test detects 5 drugs simultaneously: cannabis, cocaine, heroin, ecstasy and amphetamines. It is one of the only saliva tests in the world capable of detecting the molecule of cannabis that is found specifically in saliva.
With the NarcoCheck® Saliva test: the detection is done on the Δ9-THC, which is the molecule of cannabis that is found specifically in the mouth, because it is contained in the smoke of cannabis cigarettes. When a person smokes a joint, this smoke will contaminate the mouth and leave traces for several hours. It is these traces, the same as those sought by the Police, that our saliva test will detect. It is no longer a modified urine test, but a real innovation in salivary screening.
With the classic tests: current saliva tests are, for the most part, designed to detect in the saliva the same traces of cannabis as in the urine. However, several scientific studies have shown that barely no amount of this molecule (THC-COOH) is found in the saliva. As a result, a too high rate of false negatives is observed (the test is negative whereas it should be positive).
The benefits of saliva tests:
They are very simple to use and minimally invasive.
They can be used anywhere, at any time. No need for bathroom or special amenities. Saliva is immediately accessible.
They can be used to detect drug consumption immediately after taking, long before traces of drugs can appear in the urine, and last for several hours.
They are done in front of you, which makes them very difficult to falsify or adulterate. Salivary tests reduce the potential for cheating.
Self-screening and road safety:
Small and very simple to use, this test is perfectly suited to self-testing. Cannabis users can now reduce the risk of using marijuana or hashish by screening themselves.
NarcoCheck® Saliva testy is ideal for the screening of drivers or road professionals.
Ideal to determine if the subject is still under the influence of cannabis.
A cannabis joint usually has effect for 4 to 6 hours. As this salivary test detects cannabis use dating less than 6 hours, a positive result will logically allow us to envisage a current state of cannabic intoxication.
The principle is simple:
1 - Place the collector in the mouth until thoroughly soaked
2 - Put the collector into the tube
3 - The test starts automatically. Wait 10 mn.
4 - Read the results
Each letter on the white cassette corresponds to a drug.
A = amphetamines B = cocaine M = ecstasy/methamphetamine O = heroine/opiates T = cannabis.
C = control lines; They must always be present otherwise the test is invalid.
When a red line appears next to a drug, the test is negative for that drug.
If no line appears next to a drug, the test is positive for that drug.
This test is negative
for every drug.
This test is positive for
amphetamines and cannabis.
This test is invalid
Do not read the results.
What is the difference between Δ9-THC and THC-COOH?
The Δ9-THC (pronounced "delta 9 THC") is the name used in the raw cannabis molecule, as it is found in hashish or weed (marijuana).
Once smoked or ingested, the human body must modify this molecule in order to eliminate it. It transforms it into a sub-molecule, which will be found especially in the urine: THC-COOH (also called 11-nor-Δ9-THC-COOH).
Why is it important to judge the performance of a saliva test?
Because in the mouth, the Δ9-THC is massively found. On the other hand, barely no traces of THC-COOH are found, which becomes virtually undetectable after a few tens of minutes after smoking a joint.
To effectively detect cannabis, a saliva test must therefore be calibrated to detect Δ9-THC.
The problem is that most current salivary tests are modified urine tests, and therefore detect THC-COOH. Even at very low detection thresholds such as 12ng/ml, they become ineffective in less than an hour after the last smoked joint.
A test will therefore be much more effective in detecting Δ9-THC at 25 ng/ml than detecting THC-COOH at 12 ng/ml !
Can a saliva test replace a urine test?
No, simply because it is not made for that.
Saliva tests are actually very effective where urine tests are not at all effective. Traces of cannabis can be detected in the saliva almost immediately after its consumption, whereas it is often necessary to wait more than ten hours to see traces in the urine.
Salivary screening will thus be fully effective over a period of a few hours following drug use. This period can be more or less long depending on the metabolism of people and their level of consumption.
A saliva test can tell: "The person tested used cannabis less than 6 hours ago".
A urine test can tell:"The person tested has used cannabis in the past few days" or "The person tested consumes cannabis (more or less regularly)".
Each type of test therefore has its specificity and none can replace the other.
Excellent. One of the most reliable tests currently available
