I swear I once had a multiple choice test at school with a question about this and one of the options was "gold, frankincense and weed". One of my best friends sat next to me and we fucking lost it.
Religion class? In western Europe in most schools you can choose for an atheist approach so it's more of an ethics class. However in catholic schools we were taught about the tales of the bible and christian values. (Actual values, not the bigots' interpretations of those values.)
The Catholic high school I attended had a mandatory religion class each year, but only one of the four years was about Catholicism. The other years covered religions from ancient history, contemporary non-Christian religions, and general ethics.
A dude can suddenly talk to God through a burning bush, and then continues to talk to him face to face in a double layered tent he goes into after anointing himself and whenever he's talking to God a cloud appears at the door? Sounds a lot like Herodotus talking about the Scythians anointing themselves, going into a tent, and burning cannabis inhaling the fumes...
I've suspected for a while given an 8th century BCE mention of an Assyrian anointing oil of olive oil, myrrh, and cannabis that the original recipe before Josiah's reforms was similar, especially given the find linked above at Tel Arad, but I haven't seen anything about pottery residue in Israelite or Judean sites.
