The same research was discussed two days ago: <a href="https://news.ycombinator.com/item?id=23387374" rel="nofollow">https://news.ycombinator.com/item?id=23387374</a>
My understanding is that medieval Rabbis (notably the Maimonides) explicitly discuss cannabis consumption and its psychological effects. The plant also gets some discussion in the Talmud but in the context of its use in fabric and as candle wick. It is speculated that certain plants mentioned in the Torah refer to cannabis but these strike me as a little tenuous. At the very least the use of cannabis as an intoxicant does not seem to be explicitly mentioned in the Torah. So I wonder, if it was commonly used for that purpose in the ancient middle east, why little to no mention of this? I mean, there is a mountain of detail about all the other minutiae of ancient custom.
I've always had a pet theory that Judaism (and thus Christianity and Islam) had its roots in psilocybin mushrooms and cannabis, especially the book of Exodus. One of my Israeli friends always jokes that the story of Moses and the burning bush was actually about Moses smoking a joint, and if you imagine that Moses ate magic mushrooms when he walked up Mt Sinai, the story makes a lot more sense.
