Nope. Non-smokers health is always affected by smokers, due to the immense pollution that smoking produces.
Cigarette butts are made of plastic, and are so incredible contaminated with a plethora of toxins, that they permanently damage the soil they are laying on.... And they are EVEREYWHERE. Cut open a animal in a city, and you will find cigarette butts, especially in birds.
Cigarette ash is everywhere, no matter what you test. All top soil, all surfaces in every house, all wildlife, all vegetables, the whole ocean, EVERYTHING is, to varieng degree, contaminated with cigarette ash. The whole world is an ashtray.
Thats why smoking is the worst drug on the planet by far, even worse than any illegal drug out there. Because smoking always, without any exceptions, affects anyone first hand. One cigarette maybe isn't a big deal, but the world's populations smokes more than 5 trillion of these fuckers every fucking year.
Thats why iam so mad about smokers.
