For example, tequila is widely considered to get one drunk quickly (versus, say, whiskey or vodka). Yet, the percent of alcohol -- proof -- is almost the same (or greater for some whiskeys and vodkas). So do certain kinds of liquors get one drunk faster or more drunk overall (controlling for weight and other alcohol-processing factors)? Does % of alcohol by volume make a difference between liquors? Is proof a reliable method of measuring alcohol content?
Edit: continuing with the tequila vs. whiskey vs. vodka example, doing 5 or 6 shots of each over the same time period would have tequila getting one more drunk than vodka, and vodka getting one more drunk than whiskey.
