Whoopi smoked pot before Oscars

London: Actress Whoopi Goldberg says she smoked cannabis to calm her nerves before accepting the best supporting Oscar for her role in 1991 film `Ghost`.

The 55-year-old actress, known for her quirky personality, played Oda Mae Brown in the romantic movie starring Demi Moore and Patrick Swayze, Contactmusic reported.

"I learned a great lesson though. Never smoke pot before there`s the possibility of having to talk to one hundred million people. Smoking cigarettes and pot every now and then are one thing that relaxes me and I thought, `I`ve got to relax.`

"So I smoked this joint that was the last of my home grown and honey, when he said my name and I popped up, I was like... up the stairs one two three four five, onto the podium. There`s millions of people, OK grab the statue.` I knew I should have never had done it."

However, the `Sister Act` star admitted as soon as her mother saw her accept the award she realised she was under the influence of a drug.

Speaking during a voiceover session for her 1992 movie `The Pagemaster` in a video obtained by gossip website TMZ, Whoopi added: "My mother called me afterwards and said, `You smoked didn`t you? Your eyes were just glistening.` So I panicked and got the Oscars tape to see whether you could tell and you just couldn`t. I know you`re not supposed to admit that you smoke pot but I don`t drink alcohol!"
