In the last three years, South American cocaine traffickers aiming at lucrative European markets have increasingly turned to West Africa as a way station in the intercontinental trade. Now, the narcs are following them. Several countries, including the US, Brazil, and Colombia, are either increasing or establishing an anti-drug presence in the region in a bid to dent the traffic.

The countries of West Africa are poor, crime-ridden and beset with weak institutions, making them attractive to traffickers able to buy protection on the cheap. And with half of the world's cocaine now going up the noses or into the crack pipes of Europeans -- use rates there have doubled in the past four years, according to the UN -- traffickers are rushing to set up shop in places like Guinea-Bissau, Ghana, and Sierra Leone. One quarter or more of all cocaine headed for Europe now transits West Africa.

Colombian National Police Commander Gen. Óscar Naranjo said last week that he will soon send a 10-man anti-drug team to the region, with a headquarters in Sierra Leone. "We want to establish a common front with these countries, to help identify the Colombian traffickers who come and go," Naranjo said.

Brazil, which is itself a major consuming country as well as a transshipment point, is also sending narcs across the water. About a half-dozen agents are headed for West Africa, one foreign narcotics agent told the Los Angeles Times.

And the US DEA is getting in on the action, too. While for years, the DEA had only one office in the entire continent, in Lagos, Nigeria, it is now expanding its activities in West Africa, agency spokesman Garrison Courtney told the Times. "The drug traffic is now going both ways. Cocaine is moving through Africa and on to Europe, while precursor chemicals from China and India for making methamphetamines are now transiting through on the way to Central America and Mexico," Courtney said. Profits from the trade could be funding terrorists, he warned.

Drug busts are already on the rise in the region. In 2001, less than a ton of cocaine was seized in West Africa; by 2006, the figure was up to 14.6 tons, according to the UN. Last year, four tons were seized in Mauritania and Senegal alone, 2.5 tons were found on a Liberian freighter, and another half-ton on board a plane that crashed at Sierra Leone's international airport.

Guinea-Bissau has been an especially tempting spot for traffickers. One of the poorest nations in the world, it has a two-ship navy, no prison, and a few dozen police. Under last year, when tougher laws were passed, the maximum penalty for drug trafficking was a $1,000 fine, even if the quantity in question weighed in the tons. Two suspected members of the Colombian FARC guerrillas were arrested there in 2007 while on a drug trafficking mission -- and mysteriously released.

Now, West Africa will be treated to the tender mercies of the DEA and its homologues.
