Whoopi Goldberg wasn't just high on excitement the night that she won an Oscar in 1991
In an old video of The View
co-host, which surfaced in the Internet Thursday, she admitted she was stoned while accepting the Best Supporting Actress Oscar for her role in Ghost
"Smoking cigarettes and pot every now and then are my habits. And I thought, 'I've got to relax.' So I smoked this wonderful joint that was the last of my home grown," Goldberg explains in the video posted by TMZ
In the clip, dated August 9, 1992 and reportedly filmed during a voice-over session for The Pagemaster
, Goldberg revealed she was so shocked by her win that she was worried about making it up to the stage.
"When he [presenter Denzel Washington] said my name and I popped up, I thought, 'Oh f---...okay, up the stairs ... around to the podium … there's millions of people, pick up the statue, get the statue," she said.
While the actress was poised in her acceptance speech, she says her mother could tell her daughter was stoned because of her "glistening eyes" and later called to scold her.
"I know you're not supposed to admit that you smoke pot, but I don't drink alcohol," Goldberg says on the tape. "Just because I do it doesn't mean you should."
Calls to Goldberg's rep were not immediately returned.
