After returning from our very successful wedding and reception, folks were commenting that part of why they may have been hit a little hard by the drinking was the altitude. I asked if they had a theory as to the science behind “getting more drunk when drinking at altitude” and no one could offer a theory. Well, it has been bothering me so I went to the internet to investigate and found this:
From Modern Drunkard Magazine
Why is it when I travel from Denver to sea level I can drink like a fish and not feel drunk?It’s all about oxygen. As any physician will tell you, the higher the altitude, the more effect alcohol has on your system. They estimate two drinks at sea level are the equivalent of three to four drinks in Denver, which explains what John Denver was talking about in “Rocky Mountain High.â€
It’s a hell of a deal for us high-altitude dwellers, but why are we so deserving? Here’s how—your body needs oxygen to metabolize alcohol. Your liver combines oxygen with alcohol to produce water and CO2, thus ridding the evil liquid from your system. At higher attitudes, where the air is thinner and oxygen less readily available, the unmetabolized alcohol takes another lap around your bloodstream, letting you enjoy the full effects one more time.
And if that is true, you think, the inverse must be true as well, right? Yes, it is. All this time when we thought we were just lolly-gagging around the bars of Denver, we were in actuality in training to become the finest drinking athletes humanity has ever produced.
Just as athletes train at high attitudes to increase their bodies’ oxygen usage efficiency, so have we. The per capita drinking rate of Colorado (we rank 10th) is less than our lower-altitude peers only because, due to the altitude, it takes less to get us drunk. But when we slide down to their sea-level bars, our oxygen-efficient systems allows us to metabolize alcohol much faster, which is why some Denverites find it a Herculean task to get drunk at lower attitudes.
So, if you’re planning on getting hammered in New Orleans, you might want to take out a loan.
So there you have it, less oxygen means slower metabolizing of alcohol means getting more drunk for a similar amount of drinking. Problem xolved!
Well, while I suppose I should be completely compelled by the anecdotal experiences and a reference to “Modern Drunkard Magazine” the post spurred me to do a little Googling of my own. (Frankly, I just wasn’t buying into the assertion that the relative partial pressure of O2 in the air would effect the metabolic functioning of the liver enough to have a tangible impact on alcohol intoxication relative to alcohol intake.) After browsing a few journal articles I’ve come away with the following impressions:
1) From the University of Texas at Austin’s Addiction Science Research & Education Center (http://www.utexas.edu/research/asrec/alcoholfacts.html): “There is no credible research evidence for the following statements about alcohol use: 1) alcohol makes you more intoxicated at high altitudes, compared to sea level, 2) alcohol cures colds and intestinal infections, and 3) alcohol increases digestion of foods. (February 12, 2001)”
2) I also came across information indicating that “Alcohol creates histotoxic hypoxia. For example, an individual who has consumed 1 ounce of alcohol may have a physiological altitude of 2,000 feet.” So, rather than high altitude making a person more intoxicated it appears that alcohol creates the physiological experience of being at higher altitude. Perhaps people are confusing “drunkeness” with “altitude sickness”?
3) Perhaps the most compelling anecdote to me is that most of the people I know from high altitudes are WEAK drinkers
I just found this discussion by doing a search for “alcohol high altitude.” The reason I did this search is that I live in Colorado at about 6,000 feet and I just went to Holland where I spent a week at sea level. One night we all went out and I had the equivelant of about 10 or 12 beers, and I barely even had a buzz! And we are talking about high powered 9% alcohol Belgian beers. After a while I was just tired and went back to my hotel. This to me, is proof that alcohol has a much lesser effect at sea level. I can guarantee you that I would have been pretty hammered if I would have drank this same amount at home… and all I was was “tired” in Holland.
Hey I agree with the post, I live in washington d.c. And I go to college in new mexico, which is at 5300 feet above sea level. Right now I’m writing this on 16 beers, and I could never handle that many in nm. Its true the altitude makes a huge difference., just try it
You are not really “more drunk,” you are simply feeling the effects of the alcohol plus the effects of altitude, which are likely greater than their sums.

Just going by what I’ve read on this page, and my own experience. I don’t live at a high altitude, I’m at about 280 ft below sea level. Since moving here I’ve noticed a difference, I feel more of an effect off of less. I don’t know how the altitude sickness works . . . but I would guess that the effects of altitude would be there whether or not you were drinking. So why would a noticeable change, (feeling tipsy after two glasses of wine, instead of three) be attributed to altitude sickness versus the wine. Is it impossible to think that a change in environment could affect the human body in such a way?
However, some posts say you can drink more than at sea level and others say less. The article itself is misleading in that way.
