A friend of mine related today, as shocked as I was to hear it, that he heard that every single study that had ever been conducted on second hand smoke effects was flawed. While I was fairly shocked to hear this (if cigarette smoke causes cancer, why would second hand cigarette smoke not cause cancer?), apparently there's others who think this.
For example the site: Second hand smoke studies: the hype and deceit
"Secondhand smoke kills, according to a new study!," is frantically shouted from the bold type headlines of newspapers and magazine articles. Mostly it is uneducated and/or issue biased newspaper reporters who add the hype to the already deceitful study. Either they don't bother to read the study for themselves (or they do and don't understand the scientific implications), relying on misleading statements from the researchers themselves, or they are far more interested in the fear mongering factor that makes for good reading and do not bother to check with anyone how accurate or reliable a study is. Not to mention it is more politically correct to nod their head yes and insert their own views and conclusions based on the scary sounding research title and bits of information that they have heard.
Whether it is a reporter with no concept of what it is they are actually reporting, simply relaying the study du jour, or a health organization or researcher submitting a report, none of what they say can be taken at face value. News reports are manipulated and then hyped, as are practically all of the studies on secondhand smoke.
The site appears to go through about 10 various studies on second hand smoke, proceeding to illustrate why they don't show what they intend to show: that second hand smoke, does, indeed, cause cancer.
For once and for all: Is there current good, non-flawed evidence from studies showing that second-hand smoke does cause cancer?
