has officially gone green – as in, marijuana green.
During an appearance on Tuesday's Tonight Show with Jay Leno
, McCain discussed her new book, America, You Sexy Bitch
, which includes a section about her advocating for the legalization of pot.
"I was living in Los Angeles very briefly last year, and I was shocked at how people here smoke weed the way people in New York pour wine," she said. "Once I started doing research onto the economic benefits for our country by decriminalizing marijuana, I decided to come out publicly in support of it."
McCain repeated her comments on The View
Wednesday morning, adding that she's "not a cannabis user ... frequently."
When Barbara Walters quipped that her "father's going to be so proud," McCain responded, "He knows everything ... and he loves me."
The discussion also prompted Elisabeth Hasselbeck
to suggest a breathalizer-style system for testing marijuana users' levels of intoxication before they drive, to which Sherri Shepherd responded: "You don't leave the house when you're high."
But she didn't find any complaints from panelist Whoopi Goldberg, who's opened up about smoking pot
in the past.
