The marijuana was found to have a relatively high content of THC, the main active ingredient in cannabis, but the sample was too old to determine a precise percentage.
Researchers also could not determine whether the cannabis was smoked or ingested, as there were no pipes or other clues in the tomb of the shaman, who was about 45 years old.
The large cache was contained in a leather basket and in a wooden bowl, and was likely meant to be used by the shaman in the afterlife.
