Date of Death: October 4, 1970
Age at Death: 27
Toxicology Details: The official cause of death was an overdose of heroin, possibly combined with the effects of alcohol.
Notes: From the book "Hippie" by Barry Miles:
"Janis returned to room 105 at the Landmard Motel, where she and some of her musician's were staying, at about 1 a.m. Earlier that day her connection had delivered $50 worth of heroin to her. But her dealer himself was not an addict and whenever he received a new consignment, he usually had a "tester" check it for him to see how pure it was before stepping on it accordingly. But his tester was away. He sent it out anyway. The smack turned out to be between 50% and 80% pure - eight times stronger than people were used to. Eight people would die from using that batch over the weekend; Janis was one of them."
Janis had provided $1,500 dollars in her will for a funeral party, where The Grateful Dead performed for 200 of her friends.
