The dangers of passive smoking are now well known, but a new study, conducted by researchers at Yale University in the United States, warns of “ultra-passive smoking”. Just breathing in the smell of cold tobacco would be bad for your health.
A non-smoking area for 15 years
Study analyzes air data from a German cinema, in Mainz, which has banned its visitors from smoking for more than 15 years. Normally, the components of cigarette smoke should have completely disappeared from the building. But the researchers realized that the round trips of smoking moviegoers were enough to affect air quality.
In the space of four days, by monitoring the air quality at the time of entry and exit, they spotted an increase in 35 chemicals that go into the composition of cigarette smoke. What they call “tertiary smoke”, present on the skin, hair and clothes of smokers, is implicated.
The equivalent of 1 to 10 cigarettes
According to this study, published in Science Mag, smokers therefore carry these chemicals with them which then pass into the ambient air. They then create a risk of “ultra-passive smoking” for people around, the equivalent of 1 to 10 cigarettes depending on the substances.
Passive smoking, that is, involuntary breathing of cigarette smoke, is already responsible for 600,000 premature deaths a year, according to the World Health Organization (WHO).
