Modern cannabis history—the real, rebellious, grassroots version—you have to start with Jack Herer. He’s the guy who changed the realm of marijuana prohibition when he wrote one of the most famous books in cannabis culture, and made the case that hemp could actually save the planet.
Herer wasn’t just an author. He was a lifelong cannabis activist, an organizer, a freedom fighter, and, at times, a total thorn in the side of the establishment. His work — from writing The Emperor Wears No Clothes to founding the Hemp and Cannabis Foundation — sparked a movement that changed how people thought about weed, hemp, and even the environment itself.
And now, of course, his name lives on in one of the world’s most famous cannabis sativa strains: the award-winning Jack Herer strain is still lighting up dispensaries (and minds) around the globe.
This is the story of the man, the myth, and the movement — a little history in hemp that continues to grow greener every year.
jack herer: the man behind the movement
Before he became the “Emperor of Hemp,” Jack Herer was, in many ways, just a regular guy. A Goldwater Republican, an army veteran, and a family man—not exactly the stereotype of a radical cannabis activist. But everything changed when he walked into a shop in the early 1970s and discovered the truth about cannabis.

Following the Reefer Madness film in the 1930s through the 1960s, many Americans still believed that marijuana caused crime and moral collapse and was a gateway drug to other, more hardcore substances like heroin, and by the 1970s, they believed drug use was a serious problem in the country. Herer can be credited to shifting those attitudes to a slightly more favorable one, especially when many realized cannabis prohibition wasn’t based on science or morality—it was based on money, politics, and misinformation:
What came together, fact after empirical fact, was a picture of a world being destroyed by a malicious conspiracy to suppress, not a “killerweed” but the world’s premier renewable natural resource, for the benefit of a handful of wealthy and powerful individuals and corporations. (Herer, Introduction to “The Emperor’s Wears No Clothes”)
Herer started researching obsessively, talking to farmers, historians, and scientists. He even worked with figures like Van der Werf and Paul Stanford, who would later found The Hemp and Cannabis Foundation together. Together, they uncovered the forgotten truth about hemp as a renewable natural resource.
By 1985, that research had evolved into a book, which would forever reshape the conversation.
the emperor wears no clothes
Herer’s magnum opus, The Emperor Wears No Clothes: The Authoritative Historical Record of Cannabis and the Conspiracy Against Marijuana (catchy, right?), was self-published and sold out of a van and head shops across America. The title was a nod to the classic Hans Christian Andersen story and his way of saying the government’s narrative about cannabis was pure fiction.

Inside, Herer laid out a researched, endlessly quotable account of how hemp had been used for paper, cloth, fuel, medicine, and food throughout history and how corporate and political interests conspired to ban it (which sounds rather familiar recently…) Herer even added a $100,000 award on the back cover of some editions of the book to “anyone who can disprove the claims made within” (12th ed. 2010). There is no record to date of anyone having done so.
Jack Herer pointed out that before the marijuana prohibition laws of the 1930s, hemp production was everywhere. American farmers grew it for fiber, hemp hurds, and industrial use, and it was a staple crop from the early colonies through World War II, through the “Hemp for Victory” campaign.
Then, as quickly as it came back, it was banned again.
But the book has become the bible of cannabis activism, and it still sits on shelves today, worn and highlighted, as both a history lesson and a battle cry.
marijuana prohibition and activism
Herer’s crusade against marijuana prohibition was about liberation as much as it was about legalization. He saw hemp as Earth’s premier renewable natural resource, capable of replacing fossil fuels, plastics, and even deforestation. He believed that hemp production could repair what industrialization had damaged: the environment, the economy, and perhaps even society itself.
That’s why he founded the Hemp and Cannabis Foundation, a nonprofit dedicated to educating the public, supporting research, and helping to end marijuana prohibition through activism and science. Alongside allies like activist Paul Stanford, Herer pushed for legalization and industrial hemp agriculture decades before Congress ever debated the 2018 Farm Bill.
He also became a fixture at every Hemp Festival and cannabis rally in the country from Oregon to California to D.C, with his catchphrase “You don’t know jack… if you don’t know Jack Herer.”
His message that cannabis could heal the planet and empower the people sparked a generation of new advocates, researchers, and entrepreneurs.
Even after Herer suffered a heart attack and later a stroke, he kept going, speaking at events and fighting for the cause until he died in 2010.
His work lives on, and Jack Herer’s legacy lives on in policy, protest, and in the plant itself.

the impact of Jack Herer’s work
It’s not an exaggeration to say Jack Herer changed the course of cannabis history.
His book and activism directly inspired a wave of cannabis legalization movements across the U.S. and abroad. Many of today’s advocates credit Herer as their introduction to the movement.
The Hemp and Cannabis Foundation continues to support education and reform. His influence also lives on through organizations like NORML and countless local grassroots groups fighting for “free the plant” policies.
And then there’s his namesake: the Jack Herer strain.
Developed by Sensi Seeds in the 1990s, the strain was designed to capture the essence of Herer’s personality: uplifting, cerebral, and full of energy. This energizing sativa has won more Cannabis Cup awards than almost any other variety and remains one of the most popular weed strains in the world.
higher leaf and the cannabis industry
Today, famous brands like Higher Leaf and other dispensaries exist in part because Herer helped push the conversation from underground to mainstream. He made it possible for cannabis businesses to exist legally, ethically, and proudly.
Before Herer, the industry barely existed outside of head shops and small-time or illegal underground growers. Now, it’s a multibillion-dollar force driving innovation in medicinal, recreational, and industrial sectors.
You can walk into a store, pick up a Jack Herer strain, grab some hemp-derived lotion, and know you’re part of a lineage that began with a man selling books from a van.

hemp and the environment
Jack Herer saw hemp as more than just a crop. To him, it was a tool for saving the planet.
That might sound like a tall order, but he wasn’t wrong. Hemp production offers huge environmental advantages:
- sustainability: hemp grows fast, requires little water, and restores soil health.
- renewability: it can replace cotton, which demands massive pesticide use.
- versatility: from fiber to fuel, hemp can produce paper, cloth, biodegradable plastics, and even building materials.
- carbon capture: it absorbs CO₂ at record rates, making it a natural ally against climate change.
Long before “eco-friendly” was a buzzword, his environmental advocacy helped inspire the next wave of sustainable agriculture and green economy thinkers.
The Farm Bill and hemp legalization
Fast forward to 2018, and the Farm Bill finally caught up with Jack Herer’s dream.
For the first time in over 80 years, hemp production became legal again in the United States. The bill opened the door for farmers, researchers, and entrepreneurs to explore hemp’s potential as a sustainable industrial crop.
It was a historic moment, and unfortunately, one that Herer didn’t live to see, but one that his work absolutely helped make possible. Without decades of activism, research, and relentless truth-telling, the Farm Bill might still be stuck in committee.
Today, The Hemp and Cannabis Foundation continues to honor that mission, promoting education and policy reform while supporting both cannabis legalization and hemp innovation.

jack herer’s legacy lives on
More than a decade after his death, Jack Herer’s legacy still shapes every part of cannabis culture.
His face appears on murals, his words on protest signs, his name on products, and his ideas in every debate about sustainability and freedom.
The Jack Herer strain remains one of the most celebrated sativas in the world—a fitting tribute to a man who believed that the plant could set us free.
His book, The Emperor Wears No Clothes, continues to sell, inspire, and convert skeptics. His organization still educates. His message still resonates; he changed how the world saw cannabis.
cannabis culture and community
Jack Herer helped shape today’s cannabis community. His work created connections between people who might never have met otherwise: environmentalists, veterans, artists, farmers, entrepreneurs, scientists, and everyday cannabis enthusiasts can share a dream for a fairer, freer world. Herer’s influence can be felt in the way people gather, share, and celebrate the plant.
Modern cannabis culture values sustainability, education, and equity, and stands directly on Herer’s shoulders.
final thoughts
Jack Herer believed that hemp could help heal the planet, cannabis could help heal the people, and truth could help heal society.
He was loud, stubborn, and endlessly passionate—and it’s a good thing he was. Without him, the modern cannabis movement might look very different.
During a speech at the Hempstalk Festival in Oregon, he said, “You’ve got to be out of your mind not to smoke dope. It is the best thing the world has ever had.”
Truer words have never been spoken.
His life, his writing, and his work continue to remind us that one person, one book, and one plant can change everything.
Here’s to Jack Herer, who proved the emperor indeed wore no clothes, and all it took was his dedication to show the world the truth.
