My character is (mildly) hallucinating aboard the ship her father packed her up on. I was thinking someone putting something like LSD into her food. Her father is a wealthy merchant, and one of the men aboard the ship wants to make everyone think she's crazy (could maybe infect them?) so he can take her back to shore and ransom her but I know it's too early for LSD (first synthesized 1938).
I'm also questioning whether she could actually be taken back to shore at all, since the ship has set sail, or would they just lock her in a cabin until they got across the ocean?
I googled LSD alternatives, LSD alternatives late 1800's, natural LSD alternatives, late 1800's ship protocol, hallucinating on late 1800's ship. I'm obviously not a google master...
Thanks in advance for the help!
