Is narcotic khat funding terrorism?

The flowering shrub's leaves, twigs, and shoots are chewed, giving users a sense of mild euphoria.

It's an oval-shaped, bitter tasting leaf that makes you chatty after chewing it, while inducing a feeling of euphoria and alertness.
The East African plant khat, a mild narcotic, has been chewed for centuries by people in the Horn of Africa and parts of the Middle East for its stimulating effects. The green leaf is central to cultural and social activities for many communities across the area and key to the economic survival of thousands of khat farmers who grow it legally.
In recent years, high demand for the herbal stimulant by the Somali diaspora -- despite it being illegal in several western countries, including the U.S. -- has helped open up a booming industry in fertile parts of Kenya, such as the Meru county.
But now the livelihood of these farmers is under threat after the Netherlands, which has a vibrant Somali community and is a key khat hub to other European countries, announced a ban on all imports of the plant in January.
Until now, the Netherlands and Britain were the only major European countries allowing the trade and consumption of the flowering shrub.
"If the ban is accepted or if it is enforced, the whole Meru county, the economy of the Meru county will be crippled," says Kenyan khat farmer Edward Mutuura, who exports the majority of his crops to the Nertherlands. "The economy of the population here where khat is grown will be totally crippled and people will have no source of income," he adds.
