I dearly love archeology. Especially when it shows that as a group, we haven't changed much at all. Case in point? The world's oldest marijuana stash has been found. It's 2700 years old, and someone helpfully picked out all male plant parts (it's the female plants that are psychoactive), so it was very definitely intended for recreational, religious, or medicinal use. Or all three.
Interestingly, it was found in a tomb in China, belonging to a group of people known as the Gushi, thought to be a group of Celtic immigrants who settled in China. (I know from past research, their textiles say 'bronze age Europe', not 'iron age China'.)
Sometimes it's good to be human, and know we're in good company. Hahahahahaha.
