Cannabis, commonly called weed, was not invented by a single person. It is a plant that originally evolved naturally about 28 million years ago on the eastern Tibetan Plateau. Humans discovered and began using cannabis thousands of years ago, with the earliest recorded medicinal use dating back to around 2700 BCE in ancient China. Chinese Emperor Shen Nung, known as the "Father of Chinese Medicine," is credited with discovering its healing properties and documenting its use for ailments such as gout and rheumatism. The plant spread from Central Asia to other parts of the world over time and was historically used for medicine, fiber, and recreational purposes.
Thus, cannabis was not invented but rather discovered and utilized by ancient civilizations, notably starting in Central Asia and ancient China.
