This is a very widely held urban myth. Residents of Denver, Colorado (1600m), will tell you that one drink in Denver is the same as two in Chicago (179m). However, the research is against it. Numerous studies have shown that altitude has no effect on your blood alcohol concentration (BAC). Both high altitude and alcohol does impair your mental performance, but the two do not become especially potent when combined.
