Answer:
Passive smokers.
Step-by-step explanation:
When the cigarette is lit, only a part of the smoke is swallowed by the smoker, and about 2/3 of the smoke generated by the burning is released into the environment, through the lit tip of the product (cigarette, cigar, cigarillos and others). This affects those around you, the passive smoker who ends up suffering the same health damage as the smoker.
Passive smoker is the non-smoker who lives with smokers indoors, thus being exposed to the toxic and carcinogenic components present in the environmental tobacco smoke, which contains practically the same composition as the smoke swallowed by the smoker. There are about 4000 compounds, of which over 200 are toxic and about 40 are carcinogenic.
