Ganja is the flower of the cannabis plant used for smoking. At the end of the 19th century, this word was derived from the Sanskrit, Hindi, and Urdu word for cannabis. It is probably the most common nickname for weeds. Cannabis seeds, flowers, buds, or plants were used in Indian traditional medicine as a remedy for the overproduction of phlegm or diarrhea, and later as a pain reliever and aphrodisiac.
Today the term ganja has become popular and made its mark in the pop culture lexicon with many references in movies and music.
