METHODS OF USING CANNABIS vary.

In the New World, marihuana (maconha in Brazil) is smoked—the dried, crushed flowering tips or leaves, often mixed with tobacco in cigarettes, or "reefers."
Hasheesh, the resin from the female plant, is eaten or smoked, often in water pipes, by millions in Moslem countries of northern Africa and western Asia.
In Afghanistan and Pakistan, the resin is commonly smoked.
Asiatic Indians regularly employ three preparations narcotically: bhang consists of plants thst are gathered green, dried, and made into a drink with water or milk or into a candy (majun) with sugar and spices; charas, normally smoked or eaten with spices, is pure resin; ganjah, usually smoked with tobacco, consists of resin-rich dried tops from the female plant.
Many of these unusually potent preparations may be derived from C. indica.
