Marijuana

Cannabis, more commonly known as Marijuana, is psychoactive drug derived from the three accepted strains, Cannabis sativa, Cannabis indica, and Cannabis ruderalis. Cannabis has a long history of use as a resource for its durable hemp fibre, seed and seed oils, and was used both medicinally and recreationally before the Great War.

Background
Marijuana was popular among many, largely the Hippie and beatnik communities, and with college students trying to unwind or party. Of course, because of the communities associated with marijuana, it was largely demonized and labelled unamerican in the United States. After the Great War, marijuana has kept its reputation as a recreational drug whenever it can be grown. Thus far, the only location where it is known to have been used is New Reno.

Behind the scenes
Marijuana was a miscellaneous item set to appear in Fallout 2 and gained through a visit to the EPA, also deleted from Fallout 2.
