 Peggy Caserta claimed in her book, "Going Down With Janis" (1973), that she and Joplin had decided mutually in April 1970 to stay away from each other to avoid enabling each other's drug use.Caserta, a former Delta Air Lines stewardess and owner of one of the first clothing boutiques in the Haight Ashbury, said in the book that by September 1970, she was smuggling cannabis throughout California and had checked into the Landmark Motor Hotel because it attracted drug users.For approximately the first two weeks of Joplin's stay at the Landmark, she did not know Caserta was in Los Angeles.
