As efforts increase to legalize weed across the US, public perception of ganja seems to evolve with each joint Miley Cyrus  lights up. According to a 2013 Gallup poll, 58 percent of Americans favor legalization  of marijuana. It's far from a taboo topic in Hollywood, and more and more celebrities are getting candid about their recreational use of marijuana. Susan Sarandon confessed to being stoned at "almost all" award shows, joining the likes of Jennifer Aniston , Justin Timberlake , Kristen Stewart , and others who have no qualms with Mary Jane. In honor of 4/20, keep reading for the best celebrity revelations about getting high.
Kristen Stewart addressed her early portrayal in the media  in an interview with Vanity Fair in 2012. "You can Google my name, and one of the first things that comes up is images of me sitting on my front porch smoking a pipe with my ex-boyfriend and my dog," she said. "It was taken the day the movie came out. I was no one. I was a kid. I had just turned 18." She continued, "The next day, it was like I was a delinquent slimy idiot, whereas I'm kind of a weirdo, creative Valley girl who smokes pot . . . big deal."
Johnny Depp  and Carson Daly just might be the most surprising smoking buddies. In 2011, Carson told Vanity Fair that he and Johnny lit up cigarettes inside his TRL dressing room . Johnny smokes more than tobacco, though — he once told Film Review magazine, "I'm not a great pothead or anything like that . . . but weed is much, much less dangerous than alcohol."
Megan Fox  has made no excuses about her appreciation of marijuana. In 2009, the actress discussed the drug  in an interview with British GQ, telling the magazine that America's war on drugs is "all propaganda." She continued, "I can't tell you how much bullsh*t I've been through because I will openly say that I smoke weed. People look at it like it's this crazy, hippie, f*cked-up thing to do. And it's not! I hope they legalize it, and when they do, I'll be the first f*cking person in line to buy my pack of joints."
Madonna  infamously dropped the f-bomb 13 times during an appearance on the Late Show With David Letterman in 1994. More than 14 years later, in 2009, the Material Girl told Letterman her colorful speech was probably marijuana-induced . "It wasn't because I was excited about you. I think it may have had something to do with the joint I smoked before I came on," she said.
Jennifer Aniston  has a casual approach to cannabis. "I enjoy it once in a while. There is nothing wrong with that. Everything in moderation," she told Rolling Stone.
If you've ever seen Susan Sarandon on an award show, chances are she was high. During an appearance on Bravo's Watch What Happens Live, Andy Cohen asked Susan to name one major Hollywood event that she showed up to stoned. "Only one? I would say almost all except the Oscars," she said.
Brad Pitt  told The Hollywood Reporter that he decided to quit smoking pot  at the end of the 1990s. "I was hiding out from the celebrity thing, I was smoking way too much dope, I was sitting on the couch and just turning into a doughnut, and I really got irritated with myself."
Natalie Portman's experiences with marijuana  helped her appreciate the warrior princess she portrayed in Your Highness. She costarred in the movie with James Franco . "I love stoner comedies. I smoked weed in college, but I haven't smoked in years," she told Entertainment Weekly. "I'm too old. I wish I was that cool, but I'm like an old lady now. I'm in bed by 10 p.m. I can't do that anymore."
President Barack Obama
President Barack Obama cleared the air on his marijuana past  in 2006, two years before he was elected to the nation's highest office. "When I was a kid, I inhaled frequently. That was the point," he said.
Rihanna  has been vocal about her appreciation for marijuana — the singer often shares her experiences on Twitter and Instagram. Rihanna addressed her open attitude  in an interview with Elle UK, saying she wanted to show her real life to discredit tabloid speculation. "I'll never be a victim," she said. "That's why I'm posting pictures of myself smoking pot, to tell the truth about myself. I've got so much to think about — why bring all this extra sh*t by being dishonest?"
Justin Timberlake is "absolutely" a pot smoker , he said in an interview with Playboy. "The only thing pot does for me is it gets me to stop thinking. Sometimes I have a brain that needs to be turned off. Some people are just better high," he said. That certainly wasn't the case when he first appeared on MTV's Punk'd. "I actually stopped smoking pot for nine to 10 months after that. I was so stoned. If you ask my friends, if they're honest, they would probably say that's the only way to get me as dizzy as I was."
For Cameron Diaz , buying weed from Snoop Dogg  may have been part of growing up. "We went to high school together: he was a year older than me. I remember him there . . . he was very tall and skinny, wore lots of ponytails in his head," she said. "And I'm pretty sure I bought weed from him. I had to have."
Matt Damon  was introduced to marijuana in a safe environment. "The first time I smoked was at home with my mother and stepfather," he said during an interview on BBC's Johnny Vaughan Tonight. "They were like, 'If you are going to do this, we'd rather you did this with us.'"
Martha Stewart's party skills  should never be underestimated. During an interview with Bravo's Andy Cohen, Martha shared a story about seeing two people smoke "sloppy joints" in NYC. "Of course, I know how to roll a joint," she said, stopping short of admitting that she lights up.
In a radio interview, Lady Gaga  said she became addicted to marijuana  after using it to numb pain and take her creativity to new levels in the studio. "I have been addicted to it, and it's ultimately related to anxiety coping, and it's a form of self-medication, and I was smoking up to 15 to 20 marijuana cigarettes a day, with no tobacco," she said.
"I am in the sort of suburban-housewife category of weed smoking," John Mayer  said in a Ustream video chat . Mayer was compelled to clarify how much he smokes after his song "Who Says" was released in 2009. In the opening line, John sings, "Who says I can't get stoned?"
During Oprah Winfrey 's interview on Bravo's Watch What Happens Live, she told host Andy Cohen the last time she smoked weed was in 1982 . "Let's hang out after the show," Cohen replied. "OK," Oprah said. "I hear it's gotten better."
For Ryan Phillippe , Mary Jane just might play a role in his dream life. "The ultimate 20-year plan is to be living in the Caribbean, writing, living off the land, eating from the ocean, and probably smoking herb," he reportedly told Rolling Stone.
Miley Cyrus  isn't shy about lighting up wherever she wants. After all, the singer famously smoked a joint on stage at the 2013 MTV European Music Awards in Amsterdam, the Netherlands. Miley opened up about her views on drugs  during an interview with Rolling Stone. "Hollywood is a coke town, but weed is so much better. And Molly, too," she said. "Those are happy drugs — social drugs. They make you want to be with friends. You're out in the open. You're not in a bathroom."
