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
The scientific evidence is just not there, says But maybe we've gone past the point where anyone cares about the facts
