Infusion

This article is about the recreational narcotics used by Unggoy. For the gel used by the Forerunners and Covenant for energy, see infusion gel. "Evan Phillips"

Infusions are recreational narcotics used by the Unggoy, who add them to their portable methane tanks or suck on them from a tube.

In 2462, as a revenge for Kig-Yar nest relocations on High Charity caused by the rapidly increasing Unggoy numbers, some radical Kig-Yar shipmasters poisoned Unggoy infusion supplies, making several thousand affected Unggoy males sterile. The Covenant leadership's lack of response to this event, which became known as the "Infusion Incident", eventually caused the Unggoy to revolt, beginning the Unggoy Rebellion.

Dengo was a user of infusions as it helped pass the time while he worked in the fields of Nes'alun keep, Sanghelios.

Trivia
The Final Grunt in Halo 3 says "When I'm on the gas, I don't know what I'm doing half the time!". The "gas" may be referring to a type of infusion.
