The tomb of a 45 year old male from 2700 years ago is analyzed:
The grave goods included bridles, archery equipment, a harp, a leather basket, and a wooden bowl. Both the basket and the bowl were filled with vegetative matter - about 789 grams (~ 1 pound 11 ounces). Radiocarbon dating was performed and a calibrated date of 2,700 years BP was returned. Analysis of the vegetative material indicated it was Cannabis sativa. Furthing testing indicated it was psychoactive.
