My daughter and boyfriend were at a pool hall and left their beers on the table to play pool. Came back shortly and finished beers and left. Daughter felt very strange driving home and boyfriend did shortly after...she freaked out, hallucinated, cried and shook all night and he passed out. She couldn't get out of bed til noon yesterday, both of them missed work and they still feel horrible. She knew they'd been drugged - her research online indicates speed. Has anyone very heard of this happening? What could possess a total stranger to do this? Any advice? I'm horrified and scared.
