Herer’s passion for truth led him to research ancient texts, government archives, and scientific studies, culminating in his groundbreaking book The Emperor Wears No Clothes, first self-published in 1985. The book documented hemp’s historical importance in agriculture, industry, and medicine — and revealed how political and corporate interests fueled its global prohibition. Over time, it became the “Bible of the hemp movement,” inspiring activists, scientists, and policymakers around the world to rethink the narrative around cannabis.
Jack Herer was born on June 18, 1939, in New York City, and grew up in a traditional, patriotic American family. Like many of his generation, he served in the U.S. Army during the Korean War era, working as a military police officer. After his service, he settled in California, working in various trades
In the early 1970s, Jack became increasingly involved in cannabis culture and advocacy. He opened his first head shop, a gathering place for free thinkers, artists, and activists. These spaces exposed him to a community of people who questioned mainstream narratives and fought for personal freedoms.
In 1985, after more than a decade of research, Jack self-published his groundbreaking book, The Emperor Wears No Clothes. The book compiled government documents, historical accounts, and scientific studies proving hemp’s enormous industrial and ecological potential.
Herer’s influence grew far beyond his writing. He traveled across the United States, speaking at rallies, festivals, universities, and political events. His charisma and authenticity drew massive crowds and new supporters to the movement. He founded Help End Marijuana Prohibition (HEMP), a grassroots organization dedicated to education and legislative change
In 2000, Jack suffered a major heart attack and stroke, which slowed his physical activity but not his passion. Even in recovery, he continued to write, speak, and inspire others to continue his mission. Nearly a decade later, in 2009, after giving an impassioned speech at the Hempstalk Festival in Portland
Jack Herer’s legacy continues to thrive in every part of the cannabis world. His book remains in print, still referenced in academic and activist circles worldwide. In tribute, the Jack Herer cannabis strain a legendary, sativa-dominant hybrid was created and named in his honor, symbolizing creativity, clarity, and strength
