Rachel McAdams took marijuana to cure her insomnia on advice from her grocer - but it just made her hallucinate.
The actress suffers from insomnia and shared her plight with her grocer while she was out shopping. He assured her he had the perfect aide and handed her a bottle which smelt strongly of the substance.
After initially assuring the shopkeeper she wanted to sleep rather than "get high", Rachel became overcome with tiredness. She still couldn't get any rest, so in a fit of desperation decided to use the cannabis.
"I take the tiniest little teaspoon, brush my teeth, by the time I'm getting into bed I'm like, my brain, what's happening?" she told talk show host Jimmy Kimmel.
"I wasn’t thinking normal thoughts, I was hallucinating.
"I was lying there cursing him. And then I started to hear opera for five hours. This guy singing opera I was going crazy."
Rachel was upset by the experience so decided to revisit the store to discuss the grocer's advice. He immediately asked her how she had got on, which is when the 34-year-old star made a discovery.
"I really looked at him and his eyes were like this big. I was like, 'You're a stoner,'" she laughed.
Rachel was promoting her movie To the Wonder on the programme. Although she is a major Hollywood star she has managed to maintain some mystique around her, which she believes is in part because she lives in Toronto, Canada.
"It's not a lucrative place for paparazzi. I mean I don't even own a car. I just walk everywhere, I ride my bike," she explained.
Rachel recently split from Welsh actor Michael Sheen after a two-year romance.
