There is some thought that is was a ergot fungus that was the caused of the mayhem.
The idea is this: The poor people had to plant their crops in swamps and substandard lands, and the rye contracted this fungus. People ate the fungus, and hallucinated and had a bunch of strange behavior. Viewing the witch trials as a drug filled rage gives it a different perspective than the fictionalized version by Authur Miller.
