Archeologists unearthed a tomb in China and found that this man's friends and relatives prepared him for the after-life by packing his bow and arrow, bridles for his horses, and his pot. Not pot as the kind that usually turns up in museums as potshards. From Afarensis, a blog devoted to anthropology, evolution, and science:
The burial is that of a 45 year old male. 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.
No mention of a pipe, so I'm guessing his rolling papers rotted away.
