Hashish: Lebanon's top export

"Most summers, if Lebanon isn’t paralyzed by war, civil strife or political crisis, security forces make a show of razing hashish fields in the fertile Bekaa Valley, an exercise in futility that leaves enough crops for the drug to remain the country’s top export." I am surprised that they go back to planting hashish because the US offers them an alternative: potato seeds--kid you not--which net them 1/100th of the revenues of Hashish. (thanks Dina)
