I'm trying to wrap my head around how much vodka that is.
A BAC content of 0.4% is defined as "the lethal dose" in most medical textbooks. That's the dose where half the people that reach it do not survive, the LD50. You take 20 people off the street, make them drink til their BAC is 0.4%, and odds are good you'll kill 10 of them.
For most people, that takes something like 13 back to back shots, equivalent to 20 oz total, or 600 mL.
If this woman weighed 200 lbs (90 kg) and just straight chugged those bottles in under an hour, her BAC would've peaked around 1.6, which is 4 times the level that would kill most people outright. It would take her 85 hours after stopping drinking to "sober up" to merely the lethal level.
If she were to space it over a 24 hour bender, that would still result in a peak BAC of "merely" 1.4%, still over three times the lethal dose, with an estimated three days to return to "merely lethal" levels of sobriety.
Several thoughts on this.
That fact that this person is not dead is, by itself, impressive.
The fact that they were able to travel somewhere and pull a prank in that state is legitimately incredible. The LD50 for falls is 50 feet. In my head, I am putting this on the same level as a woman falling out of a 5 story window, staggering away, only to get apprehended later gluing googly eyes to random objects.
There was a drinking game some of my friends played in college while watching Monty Python and the Holy Grail that we always wound up cheating at, because every time we attempted it we got blitzed. We did a fully sober watch of it one time while tallying, and that drinking game would've required us to take 55 shots in order to make it through honestly. We all agreed that was ridiculous, but I am only now processing that it was ridiculous in a way that could actually get people killed. If you're making drinking games, please try to give yourself a 9 shot budget, tops.
This woman consumed the equivalent of 65 shots. Which means that she alone could pass the Monty Python drinking game.
...I wonder if the MDMA helped.
