How about Laxatives?
It seems that a lot of local merchants are getting fat in Somalia. The reason? They are making good money by financing Piracy. These guys would raise heaven and hell just to be able to get their hands to some adipex p. If I were a vessel owner, I would ship laxatives to these people, the kind that is potent for weeks. That should somehow teach them that whoever their gods are, they are being watched and will be punished.
