Your comment makes me think that the Latin speaking world likes to attribute bad plants to the devil.
There's a drug that Colombians call the Devil's Breath[1]. Which is believed to be scopolamine[2], which had previously been used as truth-serum. The rumors go that the drug makes you "zombified" and compliant, willing to do whatever is suggested to you. It's my understanding that the drug is extracted from belladonna[3] though it's hard to know what is actually true about the rumors. Vice has a video about it[4], though I haven't had the opportunity to watch it yet.
