Is nicotine dangerous in the quantities of second-hand tobacco smoke?
Well I'm sure it must be, unless the American Cancer Society, Center for Disease Control, and WHO are all wrong.
The U.S. Department of Health and Human Services says that, "There is no risk-free level of secondhand smoke exposure. Even brief exposure can be dangerous."
And...
Secondhand smoke exposure causes heart disease and lung cancer in nonsmoking adults.
Nonsmokers who are exposed to secondhand smoke at home or work increase their heart disease risk by 25–30% and their lung cancer risk by 20–30%.
Breathing secondhand smoke has immediate harmful effects on the cardiovascular system that can increase the risk of heart attack. People who already have heart disease are at especially high risk.
Secondhand smoke is classified as a "known human carcinogen" (cancer-causing agent) by the US Environmental Protection Agency (EPA), the US National Toxicology Program, and the International Agency for Research on Cancer (IARC), a branch of the World Health Organization.
Why do you say that? If secondhand campfire smoke is just as dangerous as secondhand tobacco smoke, and if secondhand tobacco smoke should not be tolerated, why should campfire smoke?
But it's not as dangerous. At all. Do you ever hear about people dying due to overexposure of campfire smoke?
Nicotine causes a central paralysing effect upon the brain and the central nervous system and as a result of absorption, acts upon different organs such as heart, eyes and intestinal tract, leading to death.
Now if this doesn't make you want to quit smoking, I don't know what will.
