I have no idea what some of the other commenters are talking about, but - 0.26 is around "blackout drunk" (I am not sure I have ever drank this much) - 0.20 is when I know that I have made a terrible mistake, definitely "wasted" as we say (though I haven't drank like this for many *many* years). - I begin to feel dizzy and ill at around 0.15ish... - 0.1 is a drunk feeling. - 0.8 is the legal driving limit in most US states. Source: I carry various breathalyzers with me whenever I drink. I probably have a higher tolerance than most though. And here are some other sources for you: https://www.utoledo.edu/studentaffairs/counseling/selfhelp/substanceuse/bac.html https://www.utoledo.edu/studentaffairs/counseling/selfhelp/s... https://en.wikipedia.org/wiki/Blood_alcohol_content https://en.wikipedia.org/wiki/Blood_alcohol_content Also, one thing to note about these charts, they are pretty conservative. One drink is rarely 0.02 unless you rarely drink, and had this one drink on an empty stomach, or are a very small person. Or maybe if you take a shot and measure it 10 minutes later.
