Khat - is it more coffee or cocaine? By Cynthia Dizikes SOURCE The Los Angeles Times

 "In the Horn of Africa and parts of the Middle East, khat is a regular part of life, often consumed at social gatherings or in the morning before work and by students studying for exams. Users chew the plant like tobacco or brew it as a tea. It produces feelings of euphoria and alertness that can verge on mania and hyperactivity depending on the variety and freshness of the plant."
