The Mates! Mod adds mates to RimWorld! What are mates, you ask? They are a non-alcoholic, non-addictive drink from Argentina (and some other places too!).
It allows your colonists to chat socially and gives them a small boost.
START: Plant some yerba mate trees and start creating some mates (on the drug spot/table) and allow your colonists to drink mates for fun!
