While hiking in the Rif mountains of Chefchaouen (the blue town in northern Morocco), I came across huge marijuana fields. Big, lush, and beautiful. The country is one of the earliest growers of cannabis and continues to be a robust producer of the plant. The product is commonly sold in resin form. Though illegal in Morocco, marijuana is unlikely to go away anytime soon. A lot of poor farmers depend on the crop for their livelihoods. One estimate of the output is $10 billion, or about 10% of the nation's economy. Recently, there's been talk of legalizing the cultivation in some form. When I think about marijuana, I'm reminded of an Ali G skit where he and an anti-drug government agent are at a table with a spread of illegal drugs. Ali G asks the agent about the effects of the drugs. With a serious demeanor, the agent talks about paranoia, racing heart, low blood pressure, wooziness ... Then Ali G asks earnestly, "Is there any negative effects?"
