Jack Herer has been played on NTS in shows including Touching Bass w/ Errol & Alex Rita, featured first on 30 September 2023. Songs played include Take Too Long.

Jack Herer(b. 1939) is the author of The Emperor Wears No Clothes (ISBN 0-9524560-0-1) (several editions since c.1985), a book which has been used in efforts to decriminalize cannabis.

A former Goldwater Republican, Herer is now a pro-marijuana and hemp activist. He has written two books, the aforementioned The Emperor Wears No Clothes and Grass. There has also been a documentary made about his life. He believes that the hemp plant should be decriminalized because it has been shown to be a renewable source of fuel, food, and medicine, and can be grown in virtually any part of the world, and that the U.S. government deliberately hides the proof of this. He has devoted his life to the support of cannabis, hemp and marijuana.

Jack Herer is also the name given to a specific strain of cannabis that is considered by Herer to be among the world's finest.

Herer ran for United States President twice, in 1988 (1,949 votes) and 1992 (3,875 votes) as the Grassroots Party candidate.

In July 2000, Herer suffered a minor heart attack and stroke, resulting in difficulties speaking and moving the right side of his body. As of May 2004, Herer has mostly recovered, claiming Cannabis Sativa was responsible for much of his recovery.
