ABC News reported that a new study suggests people were using cannabis for psychoactive purposes at least 2,800 years ago. According to the ABC News report, seeds and preserved hair in a tomb point to the "oldest signs of cannabis high" from that time.
The headline frames the finding as a suggestion from a new study rather than a settled result. ABC News's summary does not name the tomb's location or the researchers behind the study. The summary available for this story also describes the finding only in general terms.
Several details are not in the ABC News material available for this report. It does not explain how the seeds and hair were dated, or how researchers determined they were used for psychoactive purposes. It also gives no further detail on the tomb.
ABC News describes the seeds and preserved hair together as the basis for its suggestion, and the material available for this story does not say whether either finding was examined separately. The report uses "at least" for the age, which is a minimum rather than an exact date.
