These days, it seems like half of Hollywood owns a cannabis business. Hoards of celebrities have followed the path of Willie Nelson, speaking openly about their experiences with the drug and making entrepreneurial debuts in the thriving industry. But who really knows their stuff?

We scoured the internet for the best weed advice from your favorite celebs. From Jennifer Aniston to Wiz Khalifa, these stars know how to light up a blunt just as well as they light up the stage.

1. Jennifer Aniston – “Pace yourself”

While on the Howard Stern Show in 2019, Aniston was asked to give advice to a 39-year-old staff member who was going to smoke weed for the first time. Her advice, after throwing some sympathetic glances, was, “Pace yourself.”

“It’s going to be the worst day of your life or the best day of your life,” Aniston added. “Don’t worry, you’ll live.”

Aniston was known to smoke pot with her ex-husband Brad Pitt when they were married, but the actress has actually been an open book about her passion for weed since she began her rise to stardom. So, Rachel Green was a little greener than you might have thought.

2. Seth Rogen – “Start with something strong”

Howard Stern asked Seth Rogen to give advice to the same lucky staff member who previously received weed wisdom from Jennifer Aniston. Contrary to Aniston’s cautionary advice, though, Rogen advised the first-time user to “start with something strong.”

“There are some lower percentage weeds which some people like to smoke if they smoke weed all day, which are, like, enough that you will get high… but, for someone who has never smoked weed, you might want to start off with actually stronger weed, to make sure you actually feel something,” Rogen explained.

Notorious cannabis-enthusiast Seth Rogen has written and starred in multiple stoner flicks, including “Pineapple Express” and “The Night Before.” The comedian is very transparent about his cannabis use and has even been known to smoke while he writes.

3. Joseph Gordon-Levitt – “Smoke at the end of the day”

In a hilarious interview on the Jimmy Kimmel show, Joseph Gordon-Levitt described the brainstorming process behind “The Night Before,” a Christmas stoner flick starring himself, Seth Rogen, and Anthony Mackie. His takeaway: “Smoke at the end of the day.”

“We were all throwing ideas into the script last minute, and there is definitely a joint being passed around the room, starting early in the day,” Gordon-Levitt said.

The actor said he thought the weed would inspire good comedy, but quickly discovered he was the only one laughing.

“The comedy that it inspires is maybe funny to me, but… I decided to start smoking at the end of the day, after the work was done.”

Much like his buddy Seth Rogen, Gordon-Levitt has been outspoken about his cannabis use, particularly as inspiration for his work. While he may not puff, puff, pass when brainstorming in large groups anymore, he told Playboy it helps him “make connections” he wouldn’t otherwise make when he’s coming up with ideas on his own.

4. Snoop Dogg – “There’s nothing wrong with being associated with it”

This weed-loving rapper has shared a lot of canna-wisdom over the years, but one could argue this was his most inspirational interview yet.

Speaking at a Flow Kana event, Snoop Dogg launched into a motivational speech for those in the cannabis industry, saying,

“Everything (concerning cannabis) is understood to be business now. There’s a tech side to it, there’s an agricultural side to it, there’s a health side to it, there are all types of sides to it that everyone can be involved with. You don’t have to be ashamed or be afraid. It’s a business now, so there’s nothing wrong with being associated with it.”

In classic Snoop Dogg style, he later added that he had taken a hit before stepping on stage.

As a cannabis entrepreneur himself, Snoop Dogg knows a thing or two about the cannabis industry. He is the proud owner of the cannabis line “Leafs by Snoop,” and the namesake of the cannabis strain “Snoop Dogg OG.”

5. Susan Sarandon – “When you can’t find the joint that you lit, it’s probably time to stop”

In a 2016 Q&A on the Andy Cohen show, Sarandon was asked a timeless question: “How much pot is too much pot, and how do you know when you’ve had too much?” She replied, coolly,

“That’s an excellent and very responsible question. I would say, when you can’t find the joint that you lit, it’s probably time to stop.”

Best known for her role in “The Lovely Bones,” Sarandon, who uses pot to kick back on the weekends, has been quoted as saying the world would be a “better place” if people would choose cannabis over alcohol when trying to relax.

Though we can’t condone the idea that smoking a joint—or, smoking anything—is good for you, she’s right that cannabis edibles and tinctures are generally less addictive than alcohol

6. Wiz Khalifa – “Embrace it”

Called the “iconic marijuana-smoker” of his generation and proud owner of his own cannabis strain, Wiz Khalifa bestowed his wisdom on how to properly smoke weed in a 2014 interview with Power 106 Los Angeles. His advice? Smoke with friends, roll your own, and “embrace it.”

“Celebrate with friends—the more the merrier—and roll your own. Don’t do anything extra,” Khalifa said.

The rapper later mentioned that he had smoked 17 joints already that day. So, he certainly seems to have found his groove.
