Alcohol
and
energy
drinks a
dangerous
mix

Mixing
energy
drinks
with
liquor
can be a
cocktail
for
disaster,
a new
University
of
Florida
study
shows.
There's
a $5
billion
market
for
so-called
"energy"
drinks,
and it
is
fueled
largely
by
college-age
consumers
-- or
younger.
With
such
names as
"Monster,"
"Full
Throttle,"
"Red
Bull"
and "Rockstar,"
the
caffeine-laden
drinks
are
marketed
to
appeal
to the
young.
UF
researchers
found
that
college
students
who
choose
to party
like a
rockstar
at a bar
or club
by
mixing
energy
drinks
with
alcohol
are
putting
themselves
at real
risk.
Mixing
alcohol
and
energy
drinks
in
combinations
such as
the
Jager
Bomb (Jagermeister
and Red
Bull) or
Red Bull
and
vodka
isn't
just a
crime
against
taste.
Doing so
can
trick
the
brain
into
believing
you're
not as
drunk as
you are.
In the
UF
study,
appearing
in the
April
issue of
the
journal
Addictive
Behaviors,
researchers
were
posted
outside
popular
Gainesville
bars and
clubs
between
10 p.m.
and 3
a.m.
They
asked
college-age
customers
leaving
the bars
what
they had
been
drinking
and did
an
assessment
of their
sobriety.
The
patrons
were
asked
about
their
drinking
history
and
whether
or not
they
intended
to drive
that
night.
The
study
was
funded
by the
UF
President's
Office.
When the
data
from
more
than 800
randomly
selected
bar
patrons
were
compiled,
researchers
said
those
who'd
been
drinking
energy
drinks
mixed
with
alcohol
were
three
times
more
likely
to leave
highly
intoxicated
and four
times
more
likely
to
intend
to drive
than bar
patrons
who'd
been
drinking
only
alcohol.
"Previous
laboratory
research
suggests
that
when
caffeine
(a
stimulant)
is mixed
with
alcohol,
it
overcomes
the
sedating
effects
of
alcohol,"
said
Dennis
Thombs,
lead
researcher
and
associate
professor
in the
UF
College
of
Public
Health
and
Health
Professions'
department
of
behavioral
science
and
community
health.
"This
may lead
people
to drink
more or
make
uninformed
judgments
about
whether
they are
safe to
drive."
The
result
is a
partier
who is
"wide
awake
and
drunk,"
said
study
co-author
Bruce
Goldberger,
director
of
toxicology
in the
UF
College
of
Medicine
and
co-author
of the
study.
"There's
a common
misconception
that if
you
drink
caffeine
with an
alcoholic
beverage
that the
stimulant
effect
of the
caffeine
counteracts
the
depressant
effect
of the
alcohol,"
Goldberger
said.
"That is
not
true.
"We know
that
caffeine
aggravates
the
degree
of
intoxication,
which
can lead
to risky
behaviors,"
he
added.
Bar
patrons
who
reported
drinking
alcohol
mixed
with
energy
drinks
-- 6.5
percent
of study
participants
-- had
an
average
breath-alcohol
concentration
reading
of
0.109,
well
above
the
legal
driving
limit of
0.08.
Fueled
by
energy
drink
cocktails,
they
left
bars
later at
night,
drank
for
longer
stretches,
ingested
more
grams of
ethanol
and were
four
times
more
likely
to say
they
intended
to drive
within
an hour
of
leaving
the bar.
Another
researcher
who has
studied
the
combination
of
alcohol
and
energy
drinks
is Dr.
Mary
Claire
O'Brien
of the
Wake
Forest
University
School
of
Medicine.
O'Brien
says
that
mixing
the
caffeine
of
energy
drinks
with
alcohol
is like
"getting
into a
car and
stepping
on the
gas
pedal
and the
brake at
the same
time."
"Students
whose
motor
skills,
visual
reaction
times
and
judgment
are
impaired
by
alcohol
may not
perceive
that
they are
intoxicated
as
readily
when
they've
also
ingested
a
stimulant
(caffeine),"
O'Brien
said.
"Only
the
symptoms
of
drunkenness
are
reduced,
but not
the
drunkenness.
They
can't
tell if
they're
drunk;
they
can't
tell if
someone
else is
drunk.
So they
get
hurt, or
they
hurt
someone
else."
