And today we have another vaccine myth to debunk – since the CDC tobacco smoking science was wrong 50 years ago, how can we trust them about vaccines? Of course, the problem with the myth is multi-faceted, typical of every anti-vaccine trope pushed on the internet.
Let’s start right at the top – is there any evidence whatsoever that the CDC tobacco science was anything but what we know today? Spoiler alert, nope, nothing there.
I have kind of written about this subject recently, but that article focused more on the claim about “doctors endorse smoking” rather than the CDC. This is a more specific article debunking the old CDC tobacco claim – so annoying.
Despite the cancer tropes that seem to afflict Facebook and Twitter these days, which includes the laughable “Big Pharma is hiding a secret cancer cure” myth, recently published evidence shows that cancer mortality rates in the USA are dropping. This is great news if you’re wondering if cancer is an end-of-life diagnosis – science-based medicine is attacking and beating cancer with numerous strategies for each cancer. And yes, instead of hiding cancer cures, Big Pharma is providing a lot of the successful medications in treating the disease.
The report, published in the journal Cancer by researchers at the American Cancer Society, the Centers for Disease Control and Prevention, the National Cancer Institute, and the North American Association of Central Cancer Registries, provides us with the mostly good news. Cancer mortality rates, which describes the number of cancer deaths per 100,000 people per year, have dropped significantly in the USA. This drop includes most of the common cancers, such as lung, colorectal, breast, and prostate.
I’ve always been amused by marijuana advocates – they vastly overstate the benefits and understate the risks, sort of the opposite of the anti-vaccine religion. Current research on cannabis shows that there is little robust evidence supporting most of its claimed medical benefits – for example, it does not cure cancer, despite what you see on the internet. On the other hand, there has been only a small amount of research examining the risks of marijuana smoking. But a 2016 article in a major journal examined the effects of secondhand marijuana smoke, and the results should cause us to examine laws to regulate public smoking of marijuana in the same way we do cigarettes.
Here in California, we would be calling the local swat teams to round up all the cigarette smokers in a public space, if the air has even a hint of cigarette smoke. Ironically, no one seems to care about cannabis smoke wafting over us and our children. Maybe some of us just assume that secondhand marijuana smoke was inherently safer than secondhand cigarette smoke. What does the scientific evidence say?

I know I shouldn’t use the conspiracy theory fallacy when talking about the pseudoscience-pushing science deniers, who provide bread and butter of topics for skeptics. I keep observing the same ridiculous and insanely illogical arguments used in the same manner by all of the deniers, including the oft-repeated “science mistakes” trope. Honestly, I think the pseudoscience pusher meet annually in Sedona, Arizona, ground zero of woo, to discuss which trope they’re pushing this year.
The anti-vaccine zealots, creationists, anthropogenic global warming deniers, and whomever else pretends to use science to actually deny science frequently focus on this theme of “science mistakes.” And then they produce a list of cherry-picked examples that “prove” that science is wrong (see Note 1). Of course, this indicates more of a misunderstanding of what is science and the history of science than it is a condemnation of science. But your typical science denier is probably not going to let facts get in the way of maintaining faith in their beliefs. So let’s deconstruct and discredit this “science mistakes” trope.
As I have written before, there is a lot of controversy about medical uses for marijuana, although it appears to be much more of a political debate than a scientific one. There just isn’t much evidence that supports a hypothesis that marijuana has any significant therapeutic effect on diseases like cancer, neurological disorders, or other diseases.
Scientists have long suspected that smoking marijuana could be linked to lung cancer, but there has only been weak evidence supporting a causality. Recently, a 40 year review of over 49,000 men strongly suggests that smoking cannabis does indeed increase the risk of lung cancer. The study examined 49,321 men between the ages of 18 and 20 who were being enlisted in the Swedish military between 1969 and 1970, examining their health and lifestyle issues, along with their use of marijuana. The researchers reviewed other potential risk factors such as respiratory disease, other types of smoking, and socioeconomic status.

But, when I keep observing the same ridiculous and insanely illogical arguments used in the same manner by all of the deniers, I begin to wonder if they don’t get together annually at the International Society of Pseudoscience meeting, usually held in Sedona, Arizona, ground zero of woo. They obviously share their stories, because we hear the same regurgitated stories in different contexts.
The antivaccinationists, creationists, anthropogenic global warming deniers, and whomever else pretends to use science to actually deny science frequently focus on a trope that “science makes mistakes.” And then they produce a list of historical events that “prove” that science is wrong. Of course, this indicates more of a misunderstanding of what is science and the history of science than it is a condemnation of science. But your typical science denier is probably not going to let facts get in the way of maintaining faith in their beliefs. So let’s deconstruct and discredit these “science makes mistakes” tropes.
