On Election Day 2016, voters in four states — California, Massachusetts, Nevada and Maine — moved to legalize recreational marijuana, while voters in Florida, North Dakota and Arkansas approved medical marijuana measures.

Clearly, public support for pot is growing. In the past decade, the number of American adults who support marijuana legalization has nearly doubled, to 57 percent, a Pew Research Center study says. 

Still, many celebrities also are advocating for the decriminalization of marijuana nationwide.

“Weed’s been helping me out for a lot of years, so when you see somebody who is functioning – I’m the perfect example of that,” hip-hop star Wiz Khalifa recently told GQ.

Rihanna makes no secret of her appreciation of marijuana on her social media feeds. 

Notably, when speculation arose about what she was smoking on vacation in 2012, she responded on Twitter by quoting a Drake song: “Kush rolled, glass full … I prefer the better things.”

In a 2012 interview with Vanity Fair, Stewart addressed a tabloid photo of her smoking a pipe on her front porch. 

“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,” Stewart said. “Big deal.”

Fox has said America’s anti-marijuana laws are “all propaganda.”

“I can’t tell you how much ... I’ve been through because I will openly say that I smoke weed,” Fox once told British GQ. “People look at it like it’s this crazy, hippy ... thing to do. And it’s not!”

The line “I need some more marijuana” kicks off Cyrus’s 2015 song “Dooo It!” 

Some lyrics: “Yeah I smoke pot, yeah I love peace ... Yo, sing about love, love is what you need. Loving what you sing, and loving smoking weed ... Sing about peace, being high and free.”

“I smoked some weed, and that’s how I finished ‘Izzo’,” Jay-Z has said about one of his most popular singles.

“I smoke a lot of pot when I write music,” Lady Gaga told “60 Minutes” in 2011. 

She recently told radio host Elvis Duran that she has “to be high to be creative.”

Freeman more recently told the Daily Beast he want America to legalize marijuana “across the board.”

“How do I take it? However it comes! I’ll eat it, drink it, smoke it, snort it,” Freeman has said, adding that it helps him with fibromyalgia pain in his left arm. 

Justin Bieber’s been spotted smoking marijuana and accused of lighting up on more than one occasion.

During an “SNL” sketch in 2013, Bieber kind of ‘fessed up and apologized — in third person. 

“I also heard he got busted for smoking weed. And he’s really sorry about it. And people make mistakes,” Bieber said in a sketch. 

In her memoir, “Yes Please,” Poehler wrote that she smokes pot “a lot less than I used to.” The comedian also disclosed that she once “lived the life of a stoner for a year.”

“I am not one of those people who smokes weed and suddenly has a burst of creativity. I am one of those people who smokes weed and spends an hour lightening my eyebrows,” Poehler wrote. 

The comedian often inserts jokes about smoking marijuana in his stand-up routines.

No surprise here. Seth Rogen, who has written and acted in his fair share of “stoner comedies,” has said: “I smoke a lot of weed when I write, generally speaking.”

“I don’t know if it helps me write,” he told MTV in 2011. “It makes me not mind that I’m writing. And I don’t know if it makes me work better, but it makes me not care that I’m working.”

The creator of “Family Guy” says he’s even smoked marijuana with his parents. 

“There was one Thanksgiving ... my sister and I were wondering if we, in this modern era, brought some pot into the house on Thanksgiving, if they would smoke it, and so we all did,” the actor told Jimmy Fallon in 2015.  

“It was a very touching moment,” MacFarlane said. 

When Playboy asked Timberlake whether he smokes marijuana, his answer was: “Absolutely.”

“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,” Timberlake explained. “Some people are just better high.”

Goldberg loves her marijuana vape pen so much that it has a name.

“The vape pen has changed my life,” she wrote in the Cannabist magazine. “No, I’m not exaggerating. In fact, her name is Sippy. Yes, she’s a she. ... And with each sip comes relief — from pressure, pain, stress, discomfort.”

Goldberg, who suffers from glaucoma, launched a medical marijuana line targeted toward women in 2016. 

Snoop Dogg once told Jimmy Kimmel that he lit up in the bathroom of the White House. (The claim was never confirmed.)

The rapper launched his own weed line, Leafs By Snoop, in 2015. 

Marijuana “makes me feel the way I need to feel,” Snoop told Esquire in 2008. 

Harrelson has long advocated for the legalization of marijuana and is on the board of the National Organization for the Reform of Marijuana Laws (NORML).

“I don’t encourage anyone to do any drugs, but on the other hand I believe in freedom,” he explained to Vice in 2012. When asked if he smokes marijuana himself, he said: “Oh yeah.” 

Maher also sits on the board of the National Organization for the Reform of Marijuana Laws. 

Recently Maher lit up a joint on his show, “Real Time” to advocate for legalization. And in case anyone was wondering, “Yup, that was real last night,” he tweeted the next day.

Hugh Hefner was an early financial contributor to the National Organization for the Reform of Marijuana Laws.

In the book “High in America,” Hefner told the author: “Smoking helped put me in touch with the realm of the senses. I discovered a whole other dimension to sex.”

In the trailer for a film called “Ricky Williams Takes the High Road,” the former Miami Dolphins running back says, “It’s kind of true ... that I quit football to go smoke weed.”

Williams is a partner at the soon-to-open Power Plant fitness, a gym that pairs marijuana with working out. 

Galifianakis, a proponent for marijuana legalization, once and smoked what appeared to be a joint on HBO’s “Real Time with Bill Maher.”

The joint was likely not just a prop; many fellow-panelists on the show refused to even touch it on live TV. Maher did not take a hit.

The “Saturday Night Live” cast member openly uses medical marijuana for his Crohn’s disease.

“I wouldn’t be able to perform on ‘SNL’ if I couldn’t smoke weed,” he recently said in an interview.  

Mayer and his Grateful Dead bandmates in the hybrid band Dead & Co. recently pulled a stunt to fight for the legalization of marijuana. 

in an Instagram post, the singer posed, surrounded by plants, at a marijuana dispensary in Colorado. 

He’s been open about his own smoking habits, telling Rolling Stone during a 2010 interview, “After this, I’m going to go home, smoke weed, and play Modern Warfare 2. It’s what I’m going to do all night.”  

The rocker told Rolling Stone in 2012 that he doesn’t “smoke as much pot as I did at one point in my life.”

“But I think the cat’s out of the bag, and it’s gonna be legalized,” he continued.  

Etheridge started using medical marijuana after she was diagnosed with breast cancer in 2004, she told CBS News in 2014. 

The singer produces cannabis-infused wine, which she said provides “a delicious full-body buzz.”

“I’m a huge believer that if more people smoked—not just for medicinal purposes, but for lifestyle purposes, instead of drinking—the world would be a better place,” Sarandon told High Times magazine in 2015.

“My attitude about marijuana or anything is, ‘Don’t be stoned if you have to pretend you’re not’,” she added to the Daily Beast in 2014. “It does remind you of your space in the universe.”

Nelson was recently asked by the Denver Post if he considers himself a cannabis connoisseur. 

“I guess if anybody is, I would be,” said the musician and marijuana legalization activist.

Nelson launched his own marijuana brand, Willie’s Reserve, in 2016.
