that's what i bring all the time , when someone arks up at my smoking ,i ask them when was the last time you checked for radon in your home
of course they have no fucking clue what radon is , when i tell them its radiation in just about every home , they come back with ,'your talking shit"
also don't forget about arsenic in treated pine, which is known to be a carcinogen
it does not take a general practitioner to understand that all the diseases attributed to tobacco are multifactorial, often with hundreds if not thousandsof different causes which interact differently in every single human in function of hundreds of ever-changing variables.
Another complication is that all the diseases attributed to tobacco also occur in non smokers. It is therefore clear that it is impossible for multifactorial epidemiology to confidently isolate single co-factors such as primary or passive tobacco smoke exposure; thus, it is impossible to quantify the contribution (if any at all) of tobacco in a death or disease
