Why is it that some people can booze it up with the hard stuff like mad, and the next day you can't smell it on them? If I have more than 5 beers, I can smell it on myself the next day wtf?

first, alcoholic drinks usually contain thousands of chemicals. you may assume that you smell ethanol alone when youre smelling an alcoholic drink, but really, theres a decent chance youre smelling a lot of other chemicals and associate those smells with intoxication. lots of the time its the higher order alcohols (propranol etc) that have a sharper smell (think cheap vodka vs expensive vodka - expensive vodka is very smooth because its cleaner, and so a 50% solution of expensive vodka goes down the same as about a 35% solution of cheap nasty vodka...part of that has to do with higher order alcohols....ok and a bunch of esters, but thats another story) and imo these compounds are going to be responsible for a lot of that 'drunk' smell
now. your body can get rid of about 10 grams of ethanol per hour (give or take), which is how they came up with that 'one standard drink per hour' guideline to safe drinking - but this says nothing of those other chemicals i mentioned a second ago - some may take longer to get rid of, meaning that though you are no longer intoxicated the following day, that smell may linger as your body gets rid of those other compounds - because the other compounds are what you were smelling all along. people who drink a lot of alcohol (or otehr chemicals that happen to work on the same enzyme elimination pathway) stimulate their body to more efficiently remove ethanol - perhaps at a rate of 15 or 20 grams per hour. simultaneously, their brain adapts to be less affected by ethanol, and therefore they may be sober(ish) at far higher BACs than the average person. so whoever it was that asked if a person can drink half a 5th a night and pass a breathalyser the next day...the answer depends on how good their body is at getting rid of it. either way, due to sheer exposure, they will be functionally sober even at BACs that would make you or i appear intoxicated.
so cut a long story short, try to separate ethanol intoxication, and therefore breathalyser readings/ blood alcohol concentration, from the smell of alcohol on a person. theyre not neccessarily in direct proportion to one another, or related at all.
then, there are different ways your body removes chemicals from your body. sometimes it chemically changes them so that theyre easier to get rid of. other times it gets rid of them as they are. inevitably, it will get rid of them via urine, faeces, through the skin, and through the lungs. the last 2 are relevent here (since im sure no one is talking about smelling a drunk persons toilet). now. people are different, and so you will get different rates of chemical change and removal via different pathways between individuals - so what you have to do is:
consider what drink the person is having in the first place
therefore what chemicals are in it
therefore how much 'drunk' smell youre going to get via that drink
therefore what chemicals are going to be excreted by that person
and how 'drunk' that will make them smell, regardless of how drunk they actually are
where the chemicals are going to be excreted (or not)
how quickly (ie into the next day or not, based on the persons individual traits)
which you are going to smell (or not)
and there you go.
now i want to know why it is youre sniffing your coworkers. thats just disgusting![]()
