The Who Study

The World Health Organization's study is a textbook example of the right way to conduct an epidemiological study. Unfortunately for them, it yielded unexpected results.

Fact: The World Health Organization conducted a study of Environmental Tobacco Smoke (ETS) and lung cancer in Europe.

Fact: ETS is commonly referred to as Second Hand Smoke (SHS). The two terms are interchangeable.

Fact: This was a case control study using a large sample size.

Fact: The purpose of the study was to provide a more precise estimate of risk, to discover any differences between different sources of ETS, and the effect of ETS exposure on different types of lung cancer.

Fact: The study was conducted from twelve centers in seven European countries over a period of seven years.

Fact: The participants consisted of 650 patients with lung cancer and 1542 control subjects. Patients with smoking related diseases were excluded from the control group. None of the subjects in either group had smoked more than 400 cigarettes in their lifetime.

Fact: Three of the study centers interviewed family members of the participants to confirm the subjects were not smokers.

Fact: The study found no statistically significant risk existed for non-smokers who either lived or worked with smokers.

Fact: The only statistically significant number was a decrease in the risk of lung cancer among the children of smokers.

Fact: The study found a Relative Risk (RR) for spousal exposure of 1.16, with a Confidence Interval (CI) of .93 - 1.44. In layman's terms, that means

• Exposure to the ETS from a spouse increases the risk of getting lung cancer by 16%.
• Where you'd normally find 100 cases of lung cancer, you'd find 116.

• The 1.16 number is not statistically significant.

Fact: The real RR can be any number within the CI. The CI includes 1.0, meaning that the real number could be no increase at all. It also includes numbers below 1.0, which would indicate a protective effect. This means that the number 1.16 is not statistically significant.

Fact: A RR of less than 2.0 is usually written off as an insignificant result, most likely to be due to error or bias. An RR of 3.0 or higher is considered desirable. (See Epidemiology 101 for more details.)

Fact: The study found no Dose/Response relationship for spousal ETS exposure. See Epidemiology 102 for more information.

Fact: The RR for workplace ETS was 1.17 with a CI of .94 - 1.45, well below the preferred 2.0 - 3.0, and with another CI that straddled 1.0.

Fact: The RR for exposure from both a smoking spouse and a smoky workplace was 1.14, with a CI of .88 - 1.47.

Fact: The RR for exposure during childhood was 0.78, with a CI of .64 - .96. This indicates a protective effect! Children exposed to ETS in the home during childhood are 22% less likely to get lung cancer, according to this study. Note that this was the only result in the study that did not include 1.0 in the CI.

The WHO quickly buried the report. The British press got wind of it and hounded them for weeks.

Fact: On March 8, 1998, the British newspaper The Telegraph reported "The world's leading health organization has withheld from publication a study which shows that not only might there be no link between passive smoking and lung cancer but that it could have even a protective effect."

Finally, the WHO issued a press release. Although their study showed no statistically significant risk from ETS, their press release had the misleading headline "Passive Smoking Does Cause Lung Cancer - Do Not Let Them Fool You." (I say "misleading" because it would be impolite to call it an outright lie.)

Fact: In paragraph four they admitted the facts: "The study found that there was an estimated 16% increased risk of lung cancer among nonsmoking spouses of smokers. For workplace exposure the estimated increase in risk was 17%. However, due to small sample size, neither increased risk was statistically significant." (Emphasis added.)

Fact: The press release doesn't mention the one statistically significant result from the study, that children raised by smokers were 22% less likely to get lung cancer.

Fact: The WHO tried to blame the results on a small sample size. However, the in the Journal of the National Cancer Institute, where the results were published, the researchers clearly state: "An important aspect of our study in relation to previous studies is its size, which allowed us to obtain risk estimates with good statistical precision..." It should also be noted that a larger sample size wouldn't have changed the numbers significantly, just narrowed the CI a bit.

A fellow Freeper asked for a reference to the location of the text of the late 90s U.N. WHO report on second hand smoke. In searching, I discovered this little gem, which might be of interest to other Freepers.
In a WHO press release, in 1998, the following was included, as an explanation as to why the complete report had not been released:

In February 1998, according to usual scientific practice, a paper reporting the main study results was sent to a reputable scientific journal for consideration and peer review. That is why the full report is not yet publicly available. Under the circumstances, however, the authors of the study have agreed to make an abstract of the report available to the media.

It has now been 7 years, and the complete report is still suppressed.
Might it be reasonable to assume that the report was in fact buried because it did not indicate that the very basis being used to pass unreasonable laws prohibiting smoking outdoors in public parks and beaches is a fraud based on no scientific basis whatsoever?

Arbitrary, crapricious and unconstitutional comes to mind.

I thought that you might be interested in some parts of this story. I noted the part about children of smokers being less likely to get lung cancer.
by the way, I don't smoke, but don't care if people do.

Yes!  And anything by Dave Hitt we can trust, that's for sure.  Here's another one:

Oct/Nov 1999 Editorial



Smoking Does Not

Cause Lung Cancer

(According to WHO/CDC Data)*

By:  James P. Siepmann, MD

Yes, it is true, smoking does not cause lung cancer.  It is only one of many risk factors for lung cancer. I initially was going to write an article on how the professional literature and publications misuse the language by saying "smoking causes lung cancer"1,2, but the more that I looked into how biased the literature, professional organizations, and the media are, I modified this article to one on trying to put the relationship between smoking and cancer into perspective. (No, I did not get paid off by the tobacco companies, or anything else like that.)

When the tobacco executives testified to Congress that they did not believe that smoking caused cancer, their answers were probably truthful and I agree with that statement. Now, if they were asked if smoking increases the risk of getting lung cancer, then their answer based upon current evidence should have be "yes."  But even so, the risk of a smoker getting lung cancer is much less than anyone would suspect.   Based upon what the media and anti-tobacco organizations say, one would think that if you smoke, you get lung cancer (a 100% correlation) or at least expect a 50+% occurrence before someone uses the word "cause." 

Would you believe that the real number is < 10% (see Appendix A)? Yes, a US white male (USWM) cigarette smoker has an 8% lifetime chance of dying from lung cancer but the USWM nonsmoker also has a 1% chance of dying from lung cancer (see Appendix A).  In fact, the data used is biased in the way that it was collected and the actual risk for a smoker is probably less.  I personally would not smoke cigarettes and take that risk, nor recommend cigarette smoking to others, but the numbers were less than I had been led to believe.  I only did the data on white males because they account for the largest number of lung cancers in the US, but a similar analysis can be done for other groups using the CDC data.

You don't see this type of information being reported, and we hear things like, "if you smoke you will die", but when we actually look at the data, lung cancer accounts for only 2% of the annual deaths worldwide and only 3% in the US.**

When we look at the data over a longer period, such as 50 years as we did here, the lifetime relative risk is only 8 (see Appendix A).  That means that even using the biased data that is out there, a USWM smoker has only an 8x more risk of dying from lung cancer than a nonsmoker.  It surprised me too because I had always heard numbers like 20-40 times more risk.  Statistics that are understandable and make sense to the general public, what a concept!

The process of developing cancer is complex and multifactorial.  It involves genetics, the immune system, cellular irritation, DNA alteration, dose and duration of exposure, and much more. Some of the known risk factors include genetics4,5,6, asbestos exposure7, sex8, HIV status9, vitamin deficiency10, diet11,12,13, pollution14 , shipbuilding15 and even just plain old being lazy.16 When some of these factors are combined they can have a synergistic effect17, but none of these risk factors are directly and independently responsible for "causing" lung cancer!

Look in any dictionary and you will find something like, "anything producing an effect or result."18 At what level of occurrence would you feel comfortable saying that X "causes" Y?  For myself and most scientists, we would require Y to occur at least 50% of the time. Yet the media would have you believe that X causes Y when it actually occurs less than 10% of the time.

As ludicrous as that is, the medical and lay press is littered with such pabulum and gobbledygook. Even as web literate physician, it took me over 50 hours of internet time to find enough raw data to write this article.  I went through thousands of abstracts and numerous articles, only to find two articles that even questioned the degree of correlation between smoking and lung cancer (British lung cancer rates do not correlating to smoking rates)19,20 and another two articles which  questioned the link between second hand smoke (passive smoking) and lung cancer.21,22 Everywhere I looked, the information was hidden in terms like "odds ratio," "relative risk," or "annualized mortality rate." Most doctors probably could not accurately define and interpret them all these terms accurately, let alone someone outside the medical profession. The public relies on the media to interpret this morass of data, but instead they are given politically correct and biased views.

If they would say that smoking increases the incidence of lung cancer or that smoking is a risk factor in the development of lung cancer, then I would agree. The purpose of this article is to emphasize the need to use language appropriately in both the medical and scientific literature (the media, as a whole, may be a lost cause).

Everything in life has risk; just going to work each day has risk. Are we supposed to live our lives in bed, hiding under the blanket in case a tornado should come into our bedroom? We in science, have a duty to give the public accurate information and then let them decide for themselves what risk is appropriate. To do otherwise is a subtle imposition of our biases on the populace.

We must embrace Theoretics as a discipline that strives to bring objectivity and logic back into science. Every article/study has some bias in it, the goal is to minimize such biases and present the facts in a comprehensible and logical manner. Unfortunately, most scientists have never taken a course in logic, and I'm sure that English class was not their favorite. Theoretics is a field of science which focuses on the use of logic and appropriate language in order to develop and communicate scientifically credible theories and ideas which will then have experimental implications. As someone whom I respect says, "Words mean things."  Let us use language and logic appropriately in our research and in the way that we communicate information.

* * * * *

Yes, smoking is bad for you, but so is fast-food hamburgers, driving, and so on. We must weigh the risk and benefits of the behavior both as a society and as an individual based on unbiased information. Be warned though, that a society that attempts to remove all risk terminates individual liberty and will ultimately perish. Let us be logical in our endeavors and true in our pursuit of knowledge. Instead of fearful waiting for lung cancer to get me (because the media and much of the medical literature has falsely told me that smoking causes lung cancer), I can enjoy my occasional cigar even more now...now that I know the whole story.

Even more evidence that second hand smoke is little more than another media scare.
I can't believe the scientific community is refusing to allow this study to be released. Makes me wonder if some U.N. bigwig just thought the report stepped a little out of party lines and they're trying to use this as an excuse.

In any case, we need to get people to realize that smoking is a personal decision and stop the rampant laws against things which aren't hurting anybody else.

Thanks for the post. Facts will never stand in the way of the smoking ban proponents, however.

Thank you for putting this out in front of folks!!!!!

While I have never met him personally, Dave Hitt is a fine man. He does not work for the tobacco industry and undertook this research on his own dime and time.

My, my - an MD that GETS it!!!!!!!!

why in heaven's name is this not being SCREAMED from the rafters.

People like you and me gt ridiculed for saying these things with claims that we don't know what we are talking about because we do not have the "medical" background. Well here it is in black and white.

Reading these studies and properly interpretting them does not take a medical professional - all it takes is some time and the comprehension of the English language.

The problem is that the MSM and the academic grant mills are spending a lot of time and money trying to convince people that they are being hurt by the legal actions of others.

Until we can change the mindset of people who have their likes and dislikes spoon fed to them by agenda driven frauds, we lose.

These folks view themselves as safe inside society's warm cocoon and prefer groupthink and conformity over the perceived dangers of independent thought and analysis.

How do we fight that?

Because the highly paid professional ANTI's would loose all that M O N E Y they have lining their fat greedy pockets!

Oh sure.  The ones in FR that hate smokers think that we pull this information out of our butts just because they don't want to hear the truth because they can't HANDLE the truth. heh!

To which some of the FReepers in here can't do.  Period.

We have all been conned!

Where's the outrage?

From the Attorney Generals, to the Robert Wood Johnson Foundation to the state Board's of Health, City Councils and certain lawmakers, we smokers have been totally screwed.  All of the above found a way to make big bucks, and guess who is is the losing end? The SMOKERS!

I will remind you of another thing:

Big Pharmaceutical (Do Smokers Feel Used Yet?)

A long time ago people either smoked or they didn't.  It was no big deal because it wasn't an issue.  The people of earth got along fine knowing they had freedom of choice without even knowing they had it.

Then some really smart guys in white coats that work for Big Pharmaceutical got together and said, "Hey, we are always getting slammed when one of our drugs takes a dirt nap." "Wouldn't it be great if everyone in the world had to buy their nicotine from us?!"  "Think of the money we could make...  wow!"

Unfortunately there wasn't anyone around with two working brain cells to slap them on the knuckles and tell them to go home and thank God they are free citizens.

So it came to pass that Big Pharmaceutical paid groups, now known as "Antis" to make smoking politically incorrect.  Antis are very rich people today.  (But this backfired on Big Pharmaceutical when they created this monster because as the tobacco money is running out, the Antis are going after other things, like your waistline.)

The Antis made it so horrible to use a legal product that people can be beat up and killed in the name of the Smoking War, and no one will bat an eyelash.  After all, smokers don't count, they don't have any rights, and who will stand up for a cause that they created and made taboo?  That whole bit about Second Hand Smoke kills went out the window the day they started including smokeless tobacco on the bans.  The "For the good of the children" went down the drain when over time not one dime has gone to the children and all the money grabbing is as obvious as the nose on your face.

Have we, as the human race, learned anything from all of this?  Nope.  It's all about the money.  It won't stop until all freedom-loving citizens of the planet stand up and say they have had enough.  Stop this and spend money on serious stuff like feeding starving children instead of taking rights with a legal product away from adults.  Don't allow the Antis to create a problem where there was none for their own gain.

As for those guys in the white coats...  way to go Bubba!  Not since Hitler have we seen a bigger and more messed up attempt to change the human race.

Publius, just for your info, the report was eventually published. There's a copy of the abstract on the National Center for Biotechnology Information (NCBI) PubMed database.

The International Agency for Research on Cancer (IARC) used to have it posted on their site, but I can't find it under the same document title as when I downloaded it years ago. However, you can point your fellow freeper to get a copy here. The conclusion was, "Our results indicate no association between childhood exposure to ETS and lung cancer risk. We did find weak evidence of a dose-response relationship between risk of lung cancer and exposure to spousal and workplace ETS. There was no detectable risk after cessation of exposure." However, it is important to note that their calculations for childhood exposures were, "ETS exposure during childhood was not associated with an increased risk of lung cancer (odds ratio [OR] for ever exposure = 0.78; 95% confidence interval [CI] = 0.64-0.96)," which means that their data indicated that children exposed to parental smoking had less of a risk of contracting lung cancer later in life than children not exposed. So when they say childhood exposure was not associated with increased risk, they weren't lying, but they were misleading because their results did indicate it was associated with decreased risk. Pretty incredible, eh?
