As cannabis consumers become younger and younger, fewer of them know that Jack Herer is not just a popular strain. This name has a much greater significance than it might seem at first glance. In this article, you will learn who Jack Herer is and why such a popular strain is named after him.

Who is Jack Herer?

While most cannabis consumers know the popular Jack Herer strain, few know the history associated with this name. Jack Herer was an advocate for cannabis reform and legalization and became famous for his activity towards decriminalization and legalization. Herer also sought to expand hemp for industrial purposes and claimed that this plant could be used as a renewable source of medicine, food, fuel, and fiber. Herer also believed that cannabis could be grown in any area of the world and used for medicinal purposes.

Jack Herer's Life

Jack Herer was born on June 18, 1939, in Brooklyn, New York. At seventeen, he enlisted in the American army and was a strong supporter of the Vietnam War at an early age. Throughout most of the sixties, he condemned those who opposed war conflicts, going so far as to label them "un-American". By twenty, Herer was already married with three children.

In the summer of 1969, at the age of 30, Jack Herer first encountered cannabis. After falling in love with this plant and its effects, he quit his job and opened a cannabis shop in Venice Beach, then a hub of art and hippie culture. Jack Herer decided to channel his newly discovered cannabis passion. In the 70s, he became a significant representative of the cannabis legalization movement. Herer spent considerable time in the Library of Congress, studying decades of research on cannabis benefits and fiber use. He used this information while writing his book The Emperor Wears No Clothes, published in 1985, which became a turning point in his cannabis industry activist career.

After more than ten years of research and fact-gathering, Jack Herer published his legendary book The Emperor Wears No Clothes, exploring the true reasons behind cannabis criminalization in the USA. His book quickly became famous as the "holy grail" or "bible" of cannabis knowledge. It is still considered a classic and mandatory reading for anyone interested in cannabis.
