Bloodhype is a science fiction book by author Alan Dean Foster.
It is instantly addictive, followed by an extremely severe slow death, and there is no known antidote. It was a killer. It is thought that this drug was completely wiped out from the human galaxy many years ago.

But somehow, mysteriously, that dreaded substance has circulated back on Repler and threatens to wreak havoc throughout the known galaxy. Someone somewhere is secretly producing Bloodhype, but no one seems to know where or who!
