Evidence, from both written literature and archaeological sites, has suggested that cannabis was first used and eventually grown as a crop by humans in the area thousands of years ago.
This non-psychedelic cannabis, which we now refer to as hemp, was used for clothing, food, and medicine.
At some point, though, people began growing cannabis that was richer in THC for use as a psychoactive drug.
It was mostly made of cannabinol, a chemical known to show up in the air when THC-rich cannabis is burned.
But it’s possible that the site and cannabis was used for a variety of non-sacrificial funeral rituals, too.
