Many people think of 'Jamaican weed' when they hear the word 'ganja', in other words, cannabis, a preparation of the Cannabis plant intended for use as a psychoactive drug or medicine. But the word is of great antiquity. Cannabis was used by the ancient Hindus of India and Nepal thousands of years ago. The herb is called ganja or ganjika in Sanskrit and other modern Indo-Aryan languages.

Ganja is also Azerbaijan's second-largest city with a population close to 820,000. It was named Elisabethpol in the Russian Empire period. The city regained its original name Ganja in 1920 during the first part of its incorporation into the Soviet Union. However, its name was changed again in 1935 to Kirovabad and retained it throughout the later Soviet period from 1935. Finally in 1989, during Perestroika, the city regained the original name.

Finally, a ganja or ghanjah, known as kotiya in India, also refers to a large wooden trading dhow, a traditional Arab sailing vessel.
