Funny how that didn't work for Rmoney, did it??
Your pro-smoking screeds are very telling, Carol
They tell us that your ignorance isn't limited to things like climate change.
Your ignorance is infinite!! You prove it daily!!
How about the folks who study cancer??
"" Secondhand Smoke
What is secondhand smoke?
Secondhand smoke (SHS) is also known as environmental tobacco smoke (ETS). SHS is a mixture of 2 forms of smoke that come from burning tobacco:
• Sidestream smoke – smoke from the lighted end of a cigarette, pipe, or cigar
• Mainstream smoke – the smoke exhaled by a smoker
Even though we think of these as the same, they aren’t. Sidestream smoke has higher concentrations of cancer-causing agents (carcinogens) than mainstream smoke. And, it has smaller particles than mainstream smoke, which make their way into the lungs and the body’s cells more easily.
When non-smokers are exposed to SHS it is called involuntary smoking or passive smoking. Non-smokers who breathe in SHS take in nicotine and toxic chemicals by the same route smokers do. The more SHS you breathe, the higher the level of these harmful chemicals in your body.
Why is secondhand smoke a problem?
Secondhand smoke causes cancer
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.
Tobacco smoke contains more than 7,000 chemical compounds. More than 250 of these chemicals are known to be harmful, and at least 69 are known to cause cancer.
SHS has been linked to lung cancer. There is also some evidence suggesting it may be linked with childhood leukemia and cancers of the larynx (voice box), pharynx (throat), brain, bladder, rectum, stomach, and breast.
IARC reported in 2009 that parents who smoked before and during pregnancy were more likely to have a child with hepatoblastoma. This rare cancer is thought to start while the child is still in the uterus. Compared with non-smoking parents, the risk was about twice as high if only one parent smoked, but nearly 5 times higher when both parents smoked.
Secondhand smoke and breast cancer
Whether SHS increases the risk of breast cancer is an issue that’s still being studied. Both mainstream and SHS have about 20 chemicals that, in high concentrations, cause breast cancer in rodents. And we know that in humans, chemicals from tobacco smoke reach breast tissue and are found in breast milk.
One reason the link between SHS and breast cancer risk in human studies is uncertain is because breast cancer risk has not been shown to be increased in active smokers. One possible explanation for this is that tobacco smoke might have different effects on breast cancer risk in smokers and in those who are exposed to SHS.
A report from the California Environmental Protection Agency in 2005 concluded that the evidence regarding SHS and breast cancer is “consistent with a causal association” in younger women. This means the SHS acts as if it could be a cause of breast cancer in these women. The 2006 US Surgeon General’s report, The Health Consequences of Involuntary Exposure to Tobacco Smoke, sums it up by saying that there is “suggestive but not sufficient” evidence of a link.
Research is still being done, but women should be told that this possible link to breast cancer is yet another reason to avoid being around SHS.""
And so are cigars, pipes, liquor, marijuana, aresol cans, prescription (and non-prescription) medicines) those disgusting energy drinks, artificial sweeteners, fast foods and STUPIDITY in general, IGNORANCE probably being the worst of them all though...to name a few OTHER health hazardous items.
