People who smell of tobacco smoke are dangerous to the health of others

Particles from cigarette smoke can remain on smokers' clothing and body and then be released into the environment. Even in non-smoking areas, the concentration of harmful tobacco combustion products may be sufficient to threaten human health.

Particles from cigarette smoke can remain on smokers' clothing and body and then be released into the environment. Even in non-smoking areas, the concentration of harmful tobacco combustion products may be sufficient to threaten human health. This was shown by a new study that was published in Science Advances.

Tertiary smoking refers to the exposure of people to components of tobacco smoke that remain on walls, furniture, clothing and other items. In a room where no one smoked, you can be exposed to many dangerous chemical compounds, depending on who is in it or visited it before, scientists have found.

Humans often carry tertiary smoke particles from one medium to another, according to Drew Gentner, research director. He notes that it is impossible to talk about the protection of someone's health from the potential effects of cigarette smoke, even if people are not exposed to secondhand smoke.

With the help of highly sensitive devices, scientists tracked the concentration of organic compounds in the air of a cinema for a week in which no one had smoked for 15 years. The variety of volatile organic compounds found in tobacco smoke increased dramatically with the arrival of spectators.

The increase was negligible for G-rated films (no age limit), unlike R-rated films (children under 17 are not allowed without adults).

Emissions of hazardous substances to health were found to be equivalent to the harmful effects of 1 to 10 cigarettes from secondhand smoke for one hour. They peaked in the air with the arrival of the audience and gradually decreased with their departure, but did not disappear completely. Typically, an empty movie theater was left with constant pollution in the following days.

The chemicals do not completely remain in the air, but are adsorbed onto various surfaces, the researchers said. They found a predominance of nitrogen-containing compounds (in particular, nicotine) that migrated from people to indoor surfaces.

Scientists noted that the movie theater where the study was conducted is modern, large and well-ventilated. In less well ventilated areas (public transport, bars, offices and homes), similar tertiary smoke emissions are likely to result in significantly higher concentrations of many of these compounds.
