Study-abroad increase alcohol intakeFor most American students, spending a semester or two studying in a foreign country means the opportunity to improve foreign language skills and become immersed in a different culture. For others, studying abroad is more like a prolonged spring break: it can be months with fewer academic responsibilities, plentiful bars and alcohol, and parents far away.
