NarcoCheck® Saliva test to detect nicotine (tobacco) consumption.

Less invasive than a urine tests, easier to use, faster and without any manipulation!

What does this test detect?

This saliva test detects cotinine, i.e. nicotine once it has been transformed by the body.

What exactly is showing this test?

Cotinine is today recognized as the main biological marker of tobacco use.

A positive result in this test means active consumption (usually several cigarettes have been smoked).

This test will therefore tell whether or not the person tested has consumed nicotine in the last 24 to 72 hours.

Quick and easy to use

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 tobacco consumption immediately after taking, long before nicotine traces 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.

For parents...

This nicotine saliva test can be used as part of a comprehensive prevention against smoking. In most households, young people are not allowed to smoke. This is not to ruin their lives, but to protect them. Regular testing can help to enforce this rule. Many youg people will be reluctant to light a cigarette if they know they will be tested.

Tobacco has always been (along with alcohol) the first drug that young people are exposed to. The first cigarettes are smoked among friends, cousins or neighbors. They are smoked discreetly, taking care that parents do not notice. Most adult smokers started this way. Often, young people even start smoking to give in to group pressure.

Setting up regular tobacco testing in the home can give some people a timely and valid reason to refuse a cigarette: "no, I can't smoke, my parents test me".


To screen for nicotine consumption (especially cigarettes), it is possible to use urine tests or saliva tests.

The difference lies largely in the ease of use. The saliva test is considered less invasive than the urine test. The saliva test does not require any special convenience (toilet) and is done in front of you. It is therefore virtually forgery-proof.

Technically, the saliva test is much more sensitive and complex to manufacture, because traces of cotinine are less abundant in the saliva than in the urine. The saliva test is therefore a little more expensive to purchase.

No, the saliva test gives a qualitative result of the type "YES / NO" (positive or negative).

If you are looking for more complete information, like a semi-quantitative result such as "LOW, MEDIUM or HIGH consumption", please use the nicotine urine test with pre-dosage, which evaluates the amount of traces of nicotine present in the urine.
