If you’re afraid of second-hand smoke, you should also avoid cars, restaurants…and don’t even think of barbecuing.
here are just some of the chemicals present in tobacco smoke and what else contains them:
Arsenic, Benzine, Formaldehyde.
Arsenic- 8 glasses of water = 200 cigarettes worth of arsenic
Benzine- Grilling of one burger = 250 cigarettes
Formaldehyde – cooking a vegetarian meal = 100 cigarettes
When you drink your 8 glasses of tap water (64 ounces) a day, you're safely drinking up to 18,000 ng of arsenic by government safety standards of 10 nanograms/gram (10 ng/gm = 18,000ng/64oz) for daily consumption.
Am I "poisoning" you with the arsenic from my cigarette smoke? Actually, with the average cigarette putting out 32 ng of arsenic into the air which is then diluted by normal room ventilation for an individual exposure of .032 ng/hour, you would have to hang out in a smoky bar for literally 660,000 hours every day (yeah, a bit hard, right?) to get the same dose of arsenic that the government tells you is safe to drink.
So you can see why claims that smokers are "poisoning" people are simply silly.
You can stay at home all day long if you don’t want all those “deadly” chemicals around you, but in fact, those alleged 4000-7000 theorized chemicals in cigarettes are present in many foods, paints etc. in much larger quantities. And as they are present in cigarettes in very small doses, they are harmless. Sorry, no matter how much you like the notion of harmful ETS, it’s a myth.
