Ancient humans were getting high on hallucinogenic drugs during cave rituals 3,000 years ago, study claims

• Scientists have discovered the use of hallucinogenic drugs by humans 3,000 years ago.
• They believe shamans used drugs as part of rituals held at the Es Càrritx cave in Menorca.
• Previous evidence of ancient drug use had been indirect and largely based on depictions in art.

Ancient humans were getting high on hallucinogenic drugs during cave rituals 3,000 years ago, according to a new study. 

Researchers made the discovery after studying Bronze Age strands of hair found in the Es Càrritx cave on the Spanish island of Menorca.

The cave was first occupied around 3,600 years ago, and was used as a funeral space until around 2,800 years ago, the researchers said.
