One of the false claims against Cannabis Witchcraft has been the claim that cannabis and Witchcraft in general are supposedly the cause of crop failure.
In 1456 and 1457 there was unusually bad weather in Metz, France, harming many of the local crops. This was attributed to Witchcraft and major Witch Hunts resulted in numerous deaths.
In 1484 Pope Innocent VIII issued an edict entitled Summis desiderantes affectibus alleging that many men and women in collusion with the Devil supposedly caused disease and pestilence, harmed harvests and cattle, and perpetuated other heinous crimes.
