>>2768674During the Neolithic era (approx. 10,000–3,000 BCE), cannabis was one of the earliest cultivated plants, originating in East Asia/Tibetan Plateau regions for fiber, food, and psychoactive purposes. Evidence indicates its use for rope around 12,000 BC, while evidence of psychoactive use—likely in rituals—was found in 11,000–3,000 BC sites.
The neolithic period was a good time period to get high anyway.
