There are plenty of celebrities today who are upfront about their marijuana use, such as Snoop Dogg, Seth Rogen, Miley Cyrus and many, many others. But it’s not just modern celebrities who enjoy cannabis. Plenty of celebrities in the past enjoyed getting stoned just as much as the ones today do.

Here are 10 old school celebrities you probably didn’t know used marijuana.

1. Robert Mitchum

Mitchum was one of the biggest film noir stars of the 1940’s and 1950’s, and he also starred in the original Cape Fear. But in 1949, the actor was sent to prison for 60 days for “conspiracy to possess marijuana cigarettes.” Luckily it didn’t really affect his career.

2. Tony Curtis

Tony Curtis was a huge star during the 1950’s and starred in movies such as The Defiant Ones and Some Like It Hot, and he’s also actress Jamie Lee Curtis’ father. He was arrested in 1970 for possession of cannabis resin while at Heathrow airport, although he was only fined $120.

3. David Bowie

Many prominent classic rock stars are known for dabbling with cannabis, including pretty much everyone in The Beatles and the Rolling Stones. But Bowie’s never really been reported as being a major stoner. But in 1976 Bowie and some of his friends were arrested in New York for possession of half a pound of cannabis. One of the friends with Bowie at the time was none other than Iggy Pop.

4. James Garner

James Garner had a lengthy Hollywood career doing everything from starring in the TV show The Rockford Files, co-starring with Steve McQueen in The Great Escape and he even appeared in The Notebook with as an elderly version of Ryan Gosling’s character. In his 2012 memoir, Garner admitted he started using marijuana back in the 1940’s and continued to do so for the rest of his life. He wrote, “I smoked marijuana for 50 years. I don’t know where I’d be without it.”

5. Bing Crosby

Bing Crosby is probably best known to today’s generation as the star of White Christmas. But like many musicians and actors, Crosby also enjoyed cannabis. One biographer wrote that legendary musician Louis Armstrong introduced Crosby to marijuana, and one of Crosby’s sons said, “When marijuana was mentioned, he’d get a smile on his face.”

6. Marilyn Monroe

The legendary actress is known for abusing various narcotics during her life, which contributed to her untimely death. But Monroe also allegedly used marijuana, as a home video showing the actress smoking a joint was sold in 2009 for $275,000.

7. Bob Denver

Best known for playing Gilligan on Gilligan’s Island, Denver was arrested in 1998 for receiving a package containing marijuana. Denver admitted to being a cannabis user, saying, “I’ve been doing it for years.” Weirdly enough the marijuana package was supposedly sent by actress Dawn Wells, who played Mary Ann on Gilligan’s Island.

8. Peter Sellers

The legendary actor and comedian played an uptight attorney who falls in love with a stoner in a 1968 movie. But in real life, Sellers was more alike to the stoner character. Swedish actress Britt Ekland said he introduced her to marijuana on their first date in 1964, and they got married 10 days later. So it must’ve been some good stuff.

9. Ava Gardner

Gardner is another star from the Golden Era of Hollywood who enjoyed using marijuana. In fact, she was introduced to the drug by Robert Mitchum while they starred in a movie together. She said she preferred alcohol to cannabis.

10. Barbra Streisand

Streisand is actually not very hidden about her past marijuana use. She’s discussed smoking cannabis with Peter Sellers in interviews, and talked about it in various outlets. When she started playing in Vegas, she would do a routine where she would talk about how nervous she was and then she would light a fake joint on stage. Eventually she swapped in real joints for the fake ones.
