Dagobah Green

"Life creates it, makes it grow. Its energy surrounds us and binds us. Luminous beings are we, not this crude matter. You must feel the Force around you; here, between you, me, the tree, the rock, everywhere, yes. Even between the land and the ship."

- Yoda, high as a kite

Dagobah Green was a highly addictive totally awesome substance which temporarily caused its users to get high enough to actually believe in some made-up idiocy they called the Force. Yoda was known to smoke Dagobah Green during his exile on Dagobah. Lando Calrissian was a known dealer of the substance.
