The actual historical record gives no support to your "certainty" - it shows that marijuana was criminalized at the behest of recently unemployed Prohibitionists with propaganda about "crazed Mexicans."

The actual historical record is incredibly hard to discern, given that we've had half a century of propaganda to obscure the actual facts. I know what the propaganda claims to be the reasons that marijuana was made illegal, but I have no idea of the real reasons. As I said, there are certain facts about the effects of medical use which are only now beginning to be documented in a systematic fashion. And it is because of these effects, which I am certain our ancestors observed, that I think we are about to learn the real reasons it was banned in the first place.

I'm certain that marijuana was made illegal when our ancestors ca. 1900s observed the bad results of use [...] I have no idea of the real reasons.

Seldom have I seen a faster backpedal.
