And then the Big M felt compelled to remind everyone that weed killer is not a beverage and that Moore is not representing the company.
Of course when you do a stunt like this everyone goes completely unhinged, screaming that a scientist endorses drinking weed killer. As usual, it is not about thinking-- it is about harming a scientist's credibility. My demo is not about drinking weed killer-- it is about demonstrating empirically-derived biological thresholds, physiological fates of well-characterized chemicals, and understanding a herbicide's mechanisms of action.
But that's nuance and science, so don't expect them to understand that.
So for the record, don't drink weed killer. There is absolutely no evidence that glyphosate is going to kill you or even make you sick in working concentrations. However, the formulation used on plants contains surfactants, detergent-like compounds that help the chemical penetrate a leaf.
Anyone who has ever consumed soap (long story) knows that it gives you a royal case of crazy colon, and that would likely be the effect of drinking a full glass of the commercial herbicide preparation.
Moore might have been planning a long flight or a marathon run, places where a case of the urgent flaming schmootzies would be most unwelcome.
My official words- don't drink weed killers or any ag chemicals. Instead, take the time to learn how to use them safely, and always do so within the labeling guidance.
