Corey Haim died of natural causes

Corey Haim died of natural causes.

A coroner’s report into the cause of death has ruled the Canadian actor passed away from respiratory distress - not a drugs overdose, as previously believed.

While the report found traces of drugs in his system, it found none in a high enough capacity to contribute toward his death.

Upon hearing the results of the autopsy, Corey’s mother Judy told RadarOnline.com: “It’s a positive thing. I really can’t say more than that, but yes, it’s a good thing. I feel vindicated.”

The report also noted the ‘Lost Boys’ actor was suffering from the condition hypertrophic cardiomyopathy - meaning the muscle in his heart thickened, making it hard for blood to flow, and the arteries which supplied blood to Corey’s heart were also hardened.

At the time of death the 38-year-old actor’s heart was nearly twice the weight of a normal heart and some vessels were as much as 75 per cent blocked, according to the coroner’s report.

Corey passed away on March 10 at the California home he was sharing with his mother.

In other documents released by the Los Angeles County Coroner’s Office, Judy admitted to flushing several bottles of medication, including muscle relaxer Carisoprodol, down the toilet after Corey’s death. Police officers’ later discovery of these empty bottles, led to speculation Corey had taken an overdose.

The report stated: “She emptied the other bottles into the toilet 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.”

She also told police Corey may have used the illegal drug marijuana in the days before his death.

Corey had made no secret of his battles with drug abuse and in 2000 confessed to taking large quantities of the sedative Valium every day.

It appeared to be a battle he had won and in 2004 he claimed he had overcome his substance abuse problems, saying: "I'm clean, sober, humble and happy."
