From Halopedia, the Halo wiki

Polypseudomorphine, colloquially known as polly-sue[1], is a sedative used by the United Nations Space Command. Enough polypseudomorphine can keep an adult human sedated for the better part of a day.[2] A small injection of the drug can also be used to ease one's pain.[3] The Spartan-II Blue Team used polypseudomorphine to sedate Colonel Robert Watts so he could be brought back to the Office of Naval Intelligence for interrogation.[2] Jonathan Doherty used the drug to ease the pain of the dying Gage Yevgenny.[3]

The drug's name implies that it is formed from many "fake" variants of morphine. The "fake" aspect may refer to the drug being a synthetic or alternate form of morphine.
