Archaeologists from the Israel Museum and colleagues found residue of cannabis containing THC on an altar in the ancient Israelite temple of Tel Arad. Apparently, the discovery in this 2,700-year-old temple south of Tel Aviv, Israel, is the first proof that ancient Jews used weed in rituals. From the BBC News:
Researchers concluded that cannabis may have been burned in order to induce a high among worshippers.[…]
Frankincense was found on one altar, which was unsurprising because of its prominence in holy texts, the study's authors told Israeli newspaper Haaretz.[…]
However, tetrahydrocannabinol (THC), cannabidiol (CBD) and cannabinol (CBN) – all compounds found in cannabis – were found on the second altar.
