The harmful effects of second-hand smoke are still not fully understood.

Have you ever heard of passive smoking? The concept is simple and straightforward: substances released during cigarette burning imbibe furniture, fabrics or walls.

“And they can remain on these objects and surfaces for days, weeks, months, or even years and pose health risks,” completed clinical oncologist Marcelo Cruz, of Cerio Lebanon Hospital in São Paulo.

Although this problem has been described in scientific work since the 1950s, it is less known compared to secondhand smoke – when a person who is not a tobacco user inhales the smoke that is breathed in by someone nearby.

A 2009 survey in the United States found that only 43% of smokers believed that secondhand smoke would be harmful to children, while 84% said they were well aware of the dangers of secondhand smoke.
