Are you at risk from tobacco smoke in your environment?

Are your children exposed to the dangers of passive smoking ?

The NarcoCheck® Secondhand Smoke test
provides a reliable and clear answser in 10 minutes.

What is secondhand smoke ?

Also called passive smoking, the secondhand smoke (SHS) is the unintentional inhalation of smoke from one or more smokers. Passive smoking can therefore concern the smoker's entourage, the people he encounters in his daily life, but also the fetus in his mother's womb.

In tobacco smoke, there are more than 4'000 chemicals, of which at least 250 are known to be harmful, and more than 50 to be carcinogenic to humans.

What does tell you this urine test?

The NarcoCheck® Secondhand Smoke urine test can detect minute traces of nicotine in the urine. Because it is 20 times more sensitive than a conventional test of tobacco consumption (active smoking), this test will highlight the characteristic traces of the passive inhalation of nicotine.

This test is therefore a major asset in the search for risky situations, such as exposure to environmental tobacco smoke. This allows to get a real and clear warning and subsequently, to lead any necessary prevention action.

The NarcoCheck® Secondhand Smoke urine test is very easy to use at home and gives a result in 10 minutes.

It can be used with adults and children.

A positive result for this test will reveal a contamination by passive smoking.


  • This test is only relevant for non-smokers. As a matter of fact, an active smoker will also show up positive to this test, which is logical, since it will also show traces of nicotine in his urine (but in much larger quantities).

  • This test is only relevant for people who do not use any products containing nicotine (electronic cigarettes, chewing gums, transdermal patches, etc.).

  • Active tobacco consumption can be achieved through the specific test  urine test for nicotine with pre-dosage.

Impact of secondhand smoke:

Passive smoking is responsible for 600,000 premature deaths a year worldwide.

In the USA, secondhand smoke causes approximately 41'000 premature deaths each year.

For a non-smoker, exposure to cigarette smoke :

  • increases the risk of having a heart attack by 27%.
  • increases the risk of developing lung cancer (25% in a non-smoker if his spouse smokes).
  • in pregnant women, increases the risk of miscarriage, fetal delay or premature birth.
  • in infants, increases the risk of sudden death by 50%.
  • About 40% of children in the world are regularly exposed to passive smoking at home.
  • 31% of deaths attributable to passive smoking are in children.

Contrary to popular beliefs maintained by the tobacco industry, anxious to minimize the perception of this risk by the public, the smoke at the end of a cigarette is actually more toxic than the smoke inhaled by the smoker. (...) this smoke is the cause of 2 to 6 times more tumors than smoke inhaled by the smoker.

As such, exposure to tobacco smoke represents a major risk for both smokers and non-smokers. Indeed, following the inhalation by non-smokers of these toxic products (carbon monoxide, tars, particles, nicotine ...) present in tobacco smoke, we can find at significant levels in their urine these substances, which are responsible of cancers, cardiovascular diseases and respiratory diseases.
