Seattle ? Students who go abroad while in college are likely to increase or even double their alcohol intake while they’re away, a new study has found.

Drinking increased most dramatically in Europe, Australia and New Zealand, the study by researchers at the University of Washington found. Students reported drinking more when they perceived their fellow travelers were drinking more heavily, and those who planned to make drinking part of their cultural immersion did so.

The study published in the current issue of Psychology of Addictive Behaviors looked only at drinking habits of students who went abroad from the University of Washington, but UW graduate student Eric Pedersen said he would expect to get similar results at other universities.
