Lamar Odom's best friend, Jamie Sangouthai, did not OD, however he did die from a flesh-eating disease caused by dirty needles.

The 37 died of necrotizing fasciitis, which is a bacterial skin infection, and chronic intravenous narcotism, which is IV drug abuse, according to the L.A. County Coroner.

The Assistant Coroner Ed Winter says that Sangouthai did got to the hospital for the infected arm, but the disease spread quickly.

Sangouthai, who frequently appeared with Lamar and Khloe Kardashian on Khloe & Lamar died Sunday at a hospital in Los Angeles.

A source told Us Weekly, "Lamar is beside himself. This is the worst tragedy."

Sangouthai's friends from Christ the King High School have set up a GoFundMe page to help his family bring Sangouthai's body home to New York to be buried.
