Belushi achieved national fame for his work on Saturday Night Live, which he joined as an original cast member in 1975. Belushi was also known for his drug usage, and it eventually cost him his life. On March 5, 1982 Belushi, age 33, was found at his room at Bungalow #3 of the Chateau Marmont on Sunset Boulevard in Los Angeles, California. The cause of death was a speedball, an injection of cocaine and heroin. On the night of his death, he was accompanied by friends Robin Williams and Robert De Niro (at the height of their own drug exploits). . .
