Officials with the United States Fish and Wildlife Service state that a pound of rhino horns sells for over $5,000 pounds in the United States. From the US, the horn is smuggled into China and Vietnam where it is used for various purposes such as hang-over cures.
In Vietnam, crushed rhino horn was being sold for $10 per shot. The Associated Press reported that the rhino horn was more costly than cocaine in Vietnam.
