Researchers discovered burnt cannabis and frankincense at a site located in the Kingdom of Judah, which suggests ancient Israelites used cannabis.
At the shrine's entrance, they found two limestone altars. Each altar showed round heaps of black solidified organic material. Tests of this black gunk in the 1960s gave mostly inconclusive results, but researchers decided to retest this material. The new tests revealed that one altar contained burned cannabis and animal droppings and the other contained remnants of frankincense and animal fat. The researchers also noted that the cannabis indicates that people may have purposefully used the plant for its hallucinogenic ingredients, to stimulate ecstasy during cultic ceremonies.
