'20 Worst Hangover Drinks' explains which drinks produce the worst hangovers.
One of the predictive factors is the amount of congeners in alcohol. Congeners—chemical toxins produced during fermentation and aging, or added during production via certain flavorings—have a direct effect on the nervous system. When you drink alcohol, these toxins course through your bloodstream as your liver metabolizes the alcohol.
In general, darker liquors contain more congeners and cause more severe hangovers. According to a study published in Alcoholism: Clinical and Experimental Research in March by Damaris Rohsenow at Brown University's Center for Alcohol and Addiction Studies, bourbon contains 37 times the amount of congeners as vodka. The study participants who imbibed bourbon reported more severe hangovers."Finally, THE DAILY BEAST names 'The 40 Drunkest Cities'.
To compile our first annual list of the drunkest cities in America, we looked at three things: average alcohol consumption over a month, the highest levels of binge drinking, and the places where large portions of the population suffer the dire health consequences from over-imbibing.
So which cities have the biggest drinking problem? Here’s a hint: They’re disproportionately from where the winters are chilliest.
