Marijuana prohibition is the status quo in America, but it wasn't always that way. In fact, a lot of famous celebrities you know and love are the same age as prohibition, which came into effect with the passing of the Marihuana Tax Act of 1937.
Here are 10 well-known celebrities that are as old as cannabis prohibition, which the ones that are still with us will hopefully outlive.
1. Morgan Freeman
The voice of God is the biggest cannabis consumer on this list. Freeman - who is a medical marijuana patient - is a vocal advocate of its benefits.
"I have fibromyalgia pain in this arm, and the only thing that offers any relief is marijuana," he told The Daily Beast in 2015. "They're talking about kids who have grand mal seizures, and they've discovered that marijuana eases that down to where these children can have a life. That right there, to me, says, 'Legalize it across the board!'"
And when asked how he liked to consume cannabis, Freeman said, "How do I take it? However it comes! I'll eat it, drink it, smoke it, snort it!"
2. Jack Nicholson
The legendary actor left a permanent mark in cannabis culture when he split a joint on-screen with Peter Fonda in 'Easy Rider' (1969). And off-camera, he has supported legalization and called for an end to the War on Drugs.
"The narcotics industry is also enormous," he told The Daily Mail in 2011. "It funds terrorism and – this is a huge problem in America – fuels the foreign gangs. More than 85 percent of men incarcerated in America are on drug-related offenses. It costs $40,000 a year for every prisoner. If they were really serious about the economy there would be a sensible discussion about legalization."
3. George Carlin
For the late George Carlin, cannabis was a crucial part of the creative process. He used to have a puff before revising his outrageous standup sets.
"I find with pot -- I'm not a big drug user anymore, but I always have a joint somewhere near me," he told Jon Stewart in 1997. "I hardly touch it - maybe once a month. That would be frequent for me. But when I'm writing something, and I write perfectly straight, perfectly sober. And I write a whole lot of stuff - six, seven, eight, nine pages. And I really pour it out. Then, the next day, one hit - that's all I need now - one hit and it's punch-up time! Time to get this thing going. And with that sort of judicious use, I do find there's some value in it."
4. Jane Fonda
The star of the Netflix stoner comedy 'Grace and Frankie' isn't a pothead by any stretch. But Jane Fonda does enjoy the occasional toke - so long as she's not heading to the movie theater afterward.
“I’ll smoke pot every now and then,” Fonda told DuJour in 2015. "[But] I cannot see a movie on pot. The number of movies I’ve seen thinking, ‘This is probably the best I have ever seen,’ and then I’ll see it again sober and think, ‘What was I thinking?’”
Dustin Hoffman doesn't care for cannabis, but he doesn't have a problem with others enjoying it.
"I smoked marijuana first when I was 18 or 17 which was 1956 or something," he admitted in 1971. "It was available because i used to play piano in a jazz band. It was very available. Yet it wasn’t something I wanted to do daily. I just am not that type of person. I never liked to drink that much daily. There are people that do and I have nothing against it."
6. George Takei
We don't know if the 4/20 birthday boy smokes marijuana. But we do know that George Takei has no problem with Prime Minister Justin Trudeau having a puff. When Trudeau opened up about his cannabis use in 2013, Takei supported the future PM and his plan to legalize marijuana in Canada.
7. Merle Haggard
The late country singer is most famous for singing "We don't smoke marijuana in Muskogee" in the anti-pot song 'Okie from Muskogee'. But he changed his tune on cannabis years later.
"At the time I wrote 'Okie From Muskogee,' I didn't smoke," Haggard told Men's Journal in 2015. "It was '68. I had been brainwashed like most of America about what marijuana would and wouldn't do. I thought it was responsible for the flower children walking around with their mouths open. It was not so. But if a guy doesn't learn anything in 50 years, there's something wrong with him. I've learned a lot about it, and America has, too."
Now Haggard lives on through his own posthumous pot strain called Merle's Girls.
8. Garrett Morris
The original member of Saturday Night Live's 'not-ready-for-primetime players' is a passionate advocate for marijuana legalization. In fact, Garrett Morris is practically a cannabis encyclopedia. Check out his impromptu lecture on the history of marijuana prohibition in America.
9. Hunter S. Thompson
The late gonzo journalist used to smoke a joint before being interviewed so that he didn't verbally maul poor reporters.
"Right now I think it's in my interest, and ours, perhaps, and maybe in the interest of the greater good for me to smoke a joint and calm down," Thompson once told an interviewer. "It's been demonstrably proven that temper tantrums are not the best way to do interviews. And probably my life will be easier - and yours too - if I smoke a joint."
10. Billy Dee Williams
