I don't think he OD'd in the same way one would OD if they were smuggling a narcotic. He probably died from the very act of having almost two pounds of things that aren't digestable - which includes the condoms and a large amount of hash, which is not meant to be eaten. The article said he died from Septicaemia, which is bacteria, and liver failure.

The article was published by The Voice of Tazmania. Coincidently, I changed my avatar photo to a Tasmanian Devil yesterday, before reading about him.
