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.
By the way, in my story, I admit that there are many “science mistakes,” so read on. Hopefully, it’s somewhat enlightening. Continue reading “Science mistakes – debunking a trope loved by pseudoscience”
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.

I know I shouldn’t use the conspiracy theory fallacy when talking about the pseudoscience-pushing science deniers, who are the bread and butter of topics for skeptics. 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.

The New York Times article, Heartland Institute Leak, a Plan to Discredit Climate Teaching, obtained some leaked documents from the Heartland Institute, a conservative think tank that denies the link between second hand smoke and cancer; and denies anthropomorphic global warming (human-caused climate change). These documents outlined “plans to promote a curriculum that would cast doubt on the scientific finding that fossil fuel emissions endanger the long-term welfare of the planet.” According to the Heartland Institute, “Principals and teachers are heavily biased toward the alarmist perspective (pdf file).”
