The 14 Best Cannabis Documentaries (Ranked 2024)

I couldn’t find a good list of cannabis documentaries. So I created one.

Here are the 14 best docs/docuseries on Cannabis I could find.

It’s easy to watch most of these pot docs. Two are on Netflix and I found free links for most the rest.

I’ll add more later.


1) What if Cannabis Cured Cancer

“What if Cannabis Cured Cancer,” directed by Len Richmond, probes cannabis’s potential to combat cancer.

Released in 2010, this one-hour film is narrated by Emmy-winner Peter Coyote.

It investigates cannabinoids, the potent chemicals in cannabis.

The film details endocannabinoids, naturally occurring substances in humans.

These can engage cancer cells, potentially killing them safely. Key research cited includes a 1974-75 study by Dr. Albert Munson at the Medical College of Virginia.

It found THC slows the growth of lung, breast, and leukemia cancers. This significant discovery was suppressed due to the controversy over cannabis.

Dr. Manuel Guzman’s work demonstrates how THC induces apoptosis in brain tumors. Apoptosis is the process of programmed cell death, crucial for eliminating tumors.

Dr. Donald Tashkin from UCLA presents research countering myths about cannabis harming lung health.

His findings suggest cannabis has a protective effect against lung cancer.

The doc is endorsed by medical authorities like Dr. Andrew Weil. Organizations such as the Marijuana Policy Project also support its message.

These endorsements highlight the film’s potential impact on medical and legal views on cannabis.

A comedic puppet short, “Kurt Cannabis Meets Connie Cancer,” voiced by Roseanne Barr and Malcolm McDowell, adds accessibility.

“What if Cannabis Cured Cancer” calls for more scientific research and legal reform regarding cannabis.

It positions cannabis as potentially significant in future medical treatments.

2) The Union: The Business Behind Getting High

“The Union” is here to harsh your mellow about the business of bud. This joint – er, documentary – rolls deep into the seedy underbelly of the marijuana industry.

Director Brett Harvey decided to take a hit of investigative journalism and follow the money trail of Mary Jane. Turns out, it’s a pot of gold.

The film takes you on a trip from the grow-ops of BC to the coffeeshops of Amsterdam, exposing the high stakes and blunt realities along the way.

With appearances by celebs like Joe Rogan and Tommy Chong, “The Union” is like a cross between “Super Size Me” and a Cheech & Chong flick.

But beneath the smoke and jokes, it makes some pretty dank arguments about the hypocrisy and hazy logic of drug laws.

Sure, it’s a tad one-sided and might give you a serious case of the giggle fits. But it’ll also make you think twice about the real deal behind the devil’s lettuce.

Puff, puff, and pass the popcorn – this is one doob-ious documentary that’s worth taking a toke of your time for.

3) The Culture High

“The Culture High” is the sequel to “The Union” that nobody asked for, but everyone needs to see.

This time, director Brett Harvey takes a deep dive into the cultural and political buzz around the sticky icky.

And let me tell you, it’s a doozy.

It’s like a cross between a TED Talk and a Cypress Hill concert , with a sprinkle of “Reefer Madness” thrown in for good measure.

With a star-studded cast of cannabis connoisseurs, including Snoop Dogg, Wiz Khalifa, and Sir Richard Branson (yes, that Richard Branson), this documentary packs a punch.

But it’s not all just smoke and mirrors. “The Culture High” takes a hard-hitting look at the war on drugs and its impact on society.

From the racial disparities in drug arrests to the big business of Big Pharma, this film leaves no stoner unturned.

The film takes you on a journey from the streets of Colorado to the halls of Congress, exposing the half-baked policies and full-blown hypocrisy along the way.

But don’t worry, it’s not all serious business. There are plenty of giggles and you might need them to get through some of the more mind-bending parts of the doc.

Watch “it on:”The Culture High” on Amazon’s Prime Video and also (for free) on Roku, Tubi, PlutoTV (owned by Paramount+) and Freevee. Full streaming options are at

4) Black Market Marijuana (Trafficked With Mariana Van Zeller)

We thought legalizing pot would fix everything, right? Nope. It turns out, it’s more like throwing gas on the fire.

Welcome to California, where weed shops pop up faster than avocado toast in a hipster café. Mariana van Zeller dives deep into this mess, and boy, it’s wild.

We start in L.A., cruising by dispensary after dispensary. You’d think they’re legit, but here’s the kicker: most aren’t.

Enter NNERG, our guide to the $5 gram.

Yep, five bucks. While the state’s legal joints get hammered with taxes, NNERG dishes out budget buds, undercutting the pricey legals without breaking a sweat.

Now, take a ride with us up north. The scenery’s great—until you realize it’s not just redwoods growing out there.

Hidden in the green expanse, illegal farms churn out tons of weed, barely touched by the law. Penalties?

A slap on the wrist. Risky? Sure, but the payoff’s too sweet to pass up.

Van Zeller’s journey isn’t just a trip through the underbrush. It’s a look at the people tangled in the green.

We meet Buddy, the old-school grower not loving the new rules. Big business is squeezing out the little guys, and Buddy’s not having it.

This doc is an eye-opener. It shows us that California’s plan to squash the black market with legalization isn’t just failing—it’s backfiring big time.

We’re left with a booming illegal trade that’s tougher than ever. It’s a wild ride through the highs and lows of the weed biz, and it’s not slowing down anytime soon.

5) The Scientist: Are We Missing Something?

“The Scientist: Are We Missing Something?” takes us on a trip, right into the world of Dr. Raphael Mechoulam (who died in 2023). They call him the godfather of cannabis research, and wow, does he live up to the title.

Picture this: It’s the 1960s, and Mechoulam’s on a bus, not your average commute though.

He’s got 5 kilos of hash in his bag, headed to the lab. Feels like a scene from a thriller, but it’s all in the name of science.

That ride? It changed everything. That’s when Mechoulam first identified THC, the stuff in weed that gets you high.

But wait, it gets deeper. Fast forward a couple of decades, and he’s uncovering how THC talks to the body’s endocannabinoid system—yeah, we have one of those.

Turns out, our brains make their own version of cannabis. Call it internal bliss, thanks to something called anandamide. Mind blown yet?

Mechoulam’s not your typical scientist. He’s a trailblazer, pushing boundaries in a field most were too skittish to touch.

His work’s monumental, diving deep into how cannabis impacts everything from our health to how fast a baby bonds with mom.

Despite his massive contributions, Mechoulam’s name isn’t in the mainstream.

This doc, directed by Zach Klein, aims to change that. It’s a heartfelt, eye-opening look at the man behind major scientific discoveries, set against the backdrop of prohibition and stigma.

“The Scientist” isn’t just for the science buffs; it’s for anyone curious about the unsung heroes of medical research.

Mechoulam’s story is a call to rethink everything we thought we knew about one of the world’s most controversial plants.

6) Lynching Charlie Lynch

“Lynching Charlie Lynch” is a documentary that’ll make you question everything you thought you knew about the war on drugs.

This doc follows the story of Charlie Lynch, a small-town medical marijuana dispensary owner.

Despite playing by the rules of California’s legal medical marijuana program, Charlie was raided by the DEA and faced decades in prison.

It’s like a real-life episode of “Law & Order”.

But instead of solving crimes, the cops are busting down the doors of a guy trying to help cancer patients.

The doc takes us behind the scenes of Charlie’s legal battle.

It exposes the absurdity of a system that treats marijuana as a dangerous drug while letting Big Pharma run wild.

But don’t let the heavy subject matter fool you – this film has plenty of moments that will make you laugh, cry, and shake your head in disbelief.

From the eccentric cast of characters in Charlie’s hometown to the legal dream team that takes on his case, “Lynching Charlie Lynch” is a rollercoaster ride of emotions.

At its core, this documentary is a story about the human cost of the war on drugs.

7) Stoned in Suburbia

“Stoned in Suburbia,” directed by Chris Martin, is a 43-minute deep dive into Britain’s evolving cannabis culture.

It starts in the 60s, with the sexual revolution, then jumps to the punk era, and lands in modern suburbia.

This documentary isn’t just historical; it’s personal, showing how cannabis has been a quiet rebel at the party through the decades.

Chris Martin captures the essence of each era with vivid storytelling.

The music is better than in most cannabis docs.

8) American Drug War 2: Cannabis Destiny

“American Drug War 2: Cannabis Destiny” hits hard. It’s 2013, and director Kevin Booth brings us this gripping sequel.

In 90 minutes, Booth plunges into the cutting edge of cannabis research.

He’s not just observing; he’s in the trenches, becoming a foster parent to a child mandated to take heavy-duty drugs.

Here’s the real shocker: a two-year-old boy, post-brain surgery, comatose, not eating for over 40 days.

Funeral plans are drawn.

Then, a desperate, secret move by his parents. Cannabis in his feeding tube. And what do you know? The boy recovers.

This isn’t just a film; it’s a battle cry against the casualties of America’s longest war—the kids.

From Mexico’s cartel lands to a child taken from his mom for her marijuana use, Booth questions: is this a conspiracy or just profit keeping cannabis in the shadows?

Watch this. It’s about the small warriors in a huge fight, and it challenges everything we think we know about cannabis and the war on drugs.

They are all seeking relief through cannabis.

Riffe doesn’t shy away from complexity.

He brings us face-to-face with doctors, patients, politicians, and activists. You’ll hear from those who advocate for medical marijuana and those against it.

It’s a battleground, with personal stories at the heart.

Ron Mann’s 1999 doc “Grass” is an 80-minut history of cannabis.

I think Woody likes to gets high.

Freddy himself (a pot advocate) is interviewed a bunch.

The doc exposes marijuana laws’ racist origins.

Freddy shows how policies harm communities of color.
