What's the highest blood alcohol content you've ever hit?

[MASHED POTATOES. VOTE!]

I'm sure I was too drunk to know.

[angus]

2.9 promille once (so 0.29%).

ppt is the english version of what you call "promille" but that unit (parts per thousand) is used more for analyses of air quality than for blood alcohol content.  For blood alcohol we use percent.  

Mine has only been measured twice.  Both times I was was way drunk, and I'm sure my alcohol content far exceeded the 1.0% legal limit, but both times the officer didn't have the portable unit in the back of his car, so I had a ~15 minute ride, cuffed, in the back seat of the squad car to hyperventilate profusely.  Both times I was able to pull of a measurement of around 0.6% or something like that.  Low enough so that I didn't have to get a drunk driving ticket, which I understand is very, very expensive.  Once the officer made notes of the fact that I was hyperventilating profusely and the local prosecuting attorney decided to make a stink about it.  I had to hire an attorney to get me out of it, but it was still far cheaper than a drunk driving conviction would have been.

Probably around .25 or so. It's always the shots that get you.

[minionofmidas]

1.79 promille the one time I was tested. But I've definitely been drunker than that.

[Eraserhead]

Not sure. Probably pretty high.

[Ebowed]

Never measured it.  I probably haven't had more than 28 standard drinks in an evening.

[TJ in Oregon]

According to an online calculator I hit .074 once a couple years ago. Still under the legal limit, but I'd never even consider driving like that. I haven't touched alcohol in close to two months. Maybe I need to get out more.

[Snowstalker Mk. II]

Probably just above 0 after I have fondue with my family.

[Kaine for Senate '18]

0.00

[Badger]

Never had it measured.

The highest I've ever seen measured out of the hundreds (if not thousands) of DUI cases I've defended or prosecuted was just over a .40, and the old rummie was still conscious and talking!

[Bacon King]

I reached the vicinity of .30 twice as a freshman; it certainly sucked, but I learned my limits. (Never been tested, though, that's just my best estimate based on how much I drank and the effects).

[fezzyfestoon]

I don't know that when I'm at my drunkest I'm of a clear enough mind to go have my blood alcohol level tested. I did do a tool online based on guesses and I've definitely at least passed .35

that's Big Boy territory!  be careful you don't drop dead.

[fezzyfestoon]

Yeah, that's higher than I expected, I don't remember ever having been in near-death territory haha

Yeah, that's higher than I expected, I don't remember ever having been in near-death territory haha

such is often a key part of the problem!

[Boris]

Yeah, a nurse subsequently told me of my .25 BAC - the only verfiable post-blackout number I can report.

[Bacon King]

Yeah, that's higher than I expected, I don't remember ever having been in near-death territory haha

The problem with those BAC calculators is that they assume that when you drink something it automatically "enters your system," but alcohol can actually take a while for your body to digest (especially if you have a stomach-full of it already). Counting drinks alone, my highest BAC "should" have been something around a .38, but there was quite a bit of that volume that I vomited out before it did anything to me.

What normal person measures that? Stop being such a degenerate.

Normal people don't, law enforcement officers do.  Normal people have only one job:  do whatever it takes to keep your exhaust gas as non-volatile as possible in the brief time you have between being stopped for drunk driving and the time they actually administer the breath analysis.
