The world of Greenleaf has a large tropical belt, creating massive jungles and rainforests. Tropical plants provide a variety of life-saving drugs that cannot easily be synthesized in a laboratory. Major drug companies set up shop on Greenleaf, providing the bulk of work for the locals.
Some of Greenleaf’s residents, seeing the enormous profits that were being made, began to make ‘clippings’ of pharmaceutical plants and grow them privately to sell on the black market. The problem became so great that the drug companies began engineering new plant strains with traceable genetic tags, so that the confiscated merchandise could be traced back to the origin point. The technique has not yet led to any major arrests, mostly because there are dozens of small cartels, and they are difficult to track down in the jungle.
The Alliance is aware of the drug-smuggling problem out on Greenleaf, and they are clamping down on enforcement. Landing is more restricted on Greenleaf than on other Rim worlds, though smugglers who know the jungle can always find ways to sneak through.
During the War of Unification , Greenleaf represented a prize for both sides of the conflict. The planet’s medical industry was a major reason for this.
