Facepalm! Jeez there are a lot of rookies chiming on this word.

Endo as a term referring to a type of marijuana does not come from "indoor." It is a mispelling of the term Indo, which refers to one of the two species of marijuana, Cannabis Indica. Indica is said to provide more of a relaxed, body high whereas the other species, Cannabis Sativa, is said to create a higher energy, more cerebral high.
If Sativa makes you paranoid, you should try some endo.
