With reference to Jim Morrison, despite the Doctor saying it was a "Heart failure", the suspicion has always been a overdose of some illegal Drug both Cocaine & Heroin have been mentioned in various recountings by different individuals. Still nothing was substantiated, so the Death of Morrison will always be an enigma.

But judging by his past behaviour it is more than likely that it was Drug related, if not the actual cause it was certainly instrumental in his demise.
