smoke in the roomLCS Laboratory Inc offers number of tests for investigation of exposure to tobacco smoke. To make sure that you select your tests correctly, let’s discuss the difference between different forms of exposure to tobacco smoke.

Tobacco smoker is exposed to several thousand chemicals, that he/she inhales during active smoking. This is a common knowledge, that nicotine is a signature compound found in every tobacco product, but there are several hundreds even more toxic compound in sigarette smoke: benzene formaldehyde, polynuclear aromatic hydrocarbons (PAH), carbon monoxide and more.

Peopele are exposed to the secondhand smoke (SHS) when they live or work next to active smoker, typically in the same office, shop, or home. SHS consist of a mixture of 2 forms of smoke that come from burning tobacco:

cigaretteMainstream smoke: The smoke exhaled by a smoker.

Sidestream smoke: Smoke from the lighted end of a cigarette, pipe, or cigar, or tobacco burning in a hookah. This type of smoke has higher concentrations of cancer-causing agents (carcinogens) and is more toxic than mainstream smoke. It also has smaller particles than mainstream smoke. These smaller particles make their way into the lungs and the body’s cells more easily.

In other words you are exposed to the SHS if somebody smoking next to you, or you are eesposed to the smoke from the next door tenants.

Thirdhand smoke (THS) is a relatively new term, that is used to discribe tobacco residue from cigarettes, cigars, and other tobacco products that is left behind after smoking and builds up on surfaces and furnishings. To remove the residue, hard surfaces, fabrics and upholstery need to be regularly cleaned or laundered.
