" Of course all the JWs were quick to say that it must have been the apostate Israelites. But who knows..."
The J.W's could be right according to the timeline, circa 700 BCE Israel was conquered by the Assyrians, and Judah subjugated, so was "pure" worship maintained at this time ? Who knows, and who is to say that Cannabis was NOT used throughout ALL the years they worshipped ?
If JW's today want to get back to the worship of Big J as it was more than probably done, then getting high on weed it is then !
