Rachel McAdams recalls accidentally getting high and hallucinating

Rachel McAdams might have a great local grocer back home in Canada, but there was one time he greatly disappointed her. The "To The Wonder" actress recently visited "Jimmy Kimmel Live!" to talk about that bad experience, which ended with her high out of her mind and hallucinating all through the night.

"I was having a really hard time sleeping, and [my grocer] said, 'Well, I've got something for you.' And I was like, 'Oh, okay!'" McAdams recalls. "So he takes me to the back and he pulls out this little bottle with no label and it's full of this dark green substance and he's like, 'Take a whiff of that,' and it's like, well, it's marijuana."

She continues, "I was like, 'Oh, oh, no, no, no, no, no, no. I want to sleep, I don't want to get high.' And he said, 'Oh no, this will put you to sleep. It's not going to get you high, it's just going to, you know,' and I was like, 'Okay, alright.' I was pretty desperate at the time, so that night I'm getting ready for bed and I take the tiniest teaspoon -- tiny little teaspoon -- and brush my teeth. By the time I'm getting into bed, I'm like, 'What's happening?' I was not thinking normal human thoughts. I was hallucinating. I was totally hallucinating, and I'm just laying there, cursing him."

It seems like McAdams didn't get much sleep that night either, as she claims she hallucinated someone singing opera for the next five hours. As would be expected, the actress went back and had some words with her grocer.

"I said, 'I'm really upset with you, you told me this would put [me to sleep],' and he's like, 'Oh, it didn't put you to sleep?' And then I realized, I really looked at him and his eyes were like [squinting], and I was like, 'You're a stoner!'" she says.
