Rachel McAdams Talks About Using Pot [VIDEO]

Rachel McAdams might be known for her good-girl image, but the Canadian actress is making headlines for her recent interview with Jimmy Kimmel in which she talks about a bad experience she had with marijuana.

After she was having a “really hard time” sleeping, McAdams’ grocer offered her up a little something special to help get some rest.

“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,” she says, “And it’s like, it’s like… well… it’s marijuana.”

The 34-year-old “To the Wonder” star told him she just wanted to sleep, not get high. He assured her the drug was what she needed.

“I was pretty desperate at the time,” she says.

McAdams says she took a small teaspoon before bed and by the time she was ready to go to sleep, she was having hallucinations.

“I was not thinking normal, human thoughts. For, like, five hours I heard this guy singing opera in my head,” she said. “I was going crazy!”
