Cannabis has been using as an endurable fiber and a medicinal plant for thousands of years. The archeologists have found the evidence high in the Pamir Mountains that people used it 2500 years ago. It originated and well spread from east Asia. Chinese and Indian ancestors described it in medical literature and regarded it as a holy tool to communicate with gods.
Cannabis became a devil due to the criminalization and discrimination of the US government after Mexican–American War. US also urged UN to ban Cannabis worldwide by the adoption of a Single Convention on Narcotic Drugs in 1961.
