FYI:   In July 2000,Jack Herer suffered a minor heart attack and a major stroke, resulting in difficulties speaking and moving the right side of his body.[7] 

Herer mostly recovered, and claimed in May 2004 that treatment with the Amanita muscaria, a psychoactive mushroom, was the “secret”.[8]

On September 12, 2009 Herer suffered another heart attack while backstage at the Hempstalk Festival in Portland, Oregon.[9]

He was discharged to another facility on October 13, 2009. Paul Stanford of The Hemp and Cannabis Foundation said “He is waking up and gazing 

appropriately when someone is talking… but he is not really communicating in any way.”[10] He passed aged 70 on April 15, 2010 in

Eugene, Oregon, from complications related to the September 2009 heart attack.[11][12].
