Although the actor’s name had been linked to an ongoing illegal drug ring, Corey Haim’s death was not a result of any substances.

The Los Angeles County Coroner officially announced today that the Lost Boy star died on March 10 due to natural causes.

The 38-year-old, who had had troubles with addiction, passed away as a result of pneumonia complicated by an enlarged heart, bad lungs and narrowed blood vessels. While there were traces of marijuana and other medications in his system, they had “no significant contributing factors” in his death.

According to the autopsy report, Haim’s mother admitted getting rid of prescription medications in the home after his death “because she didn’t want anyone else to get hold of the medication and she didn’t know the police would be responding to her residence.”
