Poison

"What makes you think it was murder?''" "''Poison, of course. The politicians' preferred method. Found a chemical in his bloodstream, killed him right away. It's an obvious case. Politicians always have something to hide, and it always comes back to haunt them, am I right? Oh, look who I'm asking. Room full of politicians."

- Padmé Amidala and Tan Divo

Poison was a toxic substance used to either incapacitate or kill an individual.

Police inspector Tan Divo made the observation during a murder investigation that poison was the preferred method of killing by politicians. Senator Onaconda Farr, as it turned out, was murdered by his assistant, Lolo Purs, using a poison toxic to Rodians.

Dioxis gas was also a well known poison in gas form.
