The recent CNNhealth article titled “Uncontrollable Vomiting Due to Marijuana Use on Rise, Study Finds,” examined a study about a mysterious new condition known as “Cannabis hyperemesis syndrome.” Their analysis is as follows:
“Between 2005 and 2014 when only medical marijuana was legal in most states, a2020 study found nearly one in five people hospitalized for cyclical vomiting in the US reported concurrent cannabis use.”
The insinuation is that marijuana use is a causal factor for this condition, but the study in no way suggests that. Instead, it discovered the obvious: as marijuana became legalized and more widely used, more people in hospitals were reported to have used it. The study does not posit a causal connection. This is just one example of the sophisticated sophistry routinely implemented by the corporate press.
Other blatant fallacies are apparent throughout the article. Check this:
“Wang’s analysis, published Friday in the journal JAMA Network Open, found over 800,000 cases of reported vomiting in Colorado between 2013 and 2018. That was an approximate 29% increase since marijuana was legalized in the state. The rate was highest in counties with no prior marijuana dispensaries.”
Nothing but a correlation gleaned from an infinitude of external and unacknowledged factors. Correlation does not equal causation.
One bizarre study of 19 stoners from 2004 and two corollary factoids together with some fluff about how marijuana is *gasp* stronger now than it was back in the 90’s does not merit a story at all, much less the title, in the year 2021,: ” Uncontrollable Vomiting Due to Marijuana Use on Rise, Study Finds.”
