Polypseudomorphine
From Halopedia, the Halo wiki
Polypseudomorphine is a sedative in use by the UNSC. It is found in many, if not all, of the Health Packs that are used on UNSC ships and facilities. Enough Polypseudomorphine can knock out a person for the better part of a day[1]. The drug is usually used for battlefield triage, but some ONI special forces teams also use it to knock out suspects so they can be captured.
