One in
four people in their early 20s have done it-mixed the stimulating effects of an
energy drink with the buzz-inducing properties of alcohol. While partiers swig
and stay out late, health experts worry that alcoholic energy drinks cloud
their judgment in two important ways: by making people think they are not as
drunk as if they'd only had alcohol, and causing them to crave another round
more strongly. These effects could explain why people who add caffeine to their
cocktail are at greater risk of being in an accident or making a decision they
will later regret (like getting in the car with a drunk driver) than those who
stick to straight booze.
When
the world's first energy drink debuted in 1987, it didn't take long for Red
Bull to find its way behind the bar. Bartenders soon started mixing Red Bull,
Monster, and Rockstar with vodka, gin, Jagermeister, and hard cider. These
caffeine-laced cocktails became so popular, major beverage companies created
canned and bottled versions like Four Loko to sell in convenience stores.
"Since
caffeine lasts for six hours, that extends that time when you feel alert, and
that makes you want to drink more."
