Muslim community leaders in Texas are protesting the latest outbreak of the perennial hype over the khat plant and its supposed links to terrorism. It began when a traffic stop near Houston last year turned up two men chewing the midly psychoactive but thoroughly illegal leaf. This sparked a year-long investigation involving local, state and federal agencies that has so far resulted in more than a half-dozen arrests. The Texas Department of Public Safety took the opportunity to link khat to terrorism in its statewide threat assessment. The statement referred to the "chewable narcotic plant grown in the Horn of Africa whose sale abroad is suspected to benefit Africa-based terrorist organizations such as al-Shabaab." That assessment, the Austin American-Statesman reported last month, was based on Congressional testimony given more than a decade ago by Steven McCraw—then-FBI-assistant director, now DPS director—who said it is likely that khat proceeds "pass through the hands of suspected [Islamic militants] and other persons with possible ties to terrorist groups."
