Kurt Cobain Murder Theory Flaws: The Overdose


Tom Grant and murder theorists contend that Kurt Cobain’s blood levels of morphine were so high when he died he could not have pulled the trigger of his Remington Model 11 20 gauge shotgun because he was unconscious from a heroin overdose with blood levels of 1.52 milligrams of morphine per liter.

Tom Grant writes:

Cobain’s heroin, (morphine), blood level was 1.52 mgs per liter. This would require a minimum injection of 225 mgs of heroin, three times a lethal dose, even for a hardcore heroin addict. The drug Diazepam, was also found in Cobain’s blood system.

The problem is that the reality of drug tolerance renders the theory impossible to prove without knowing exactly what his tolerance level was, which is exactly what the toxicologists have said. Addicts routinely inject huge quantities of heroin and experience no more than typical highs, while nurses at methadone clinics have been known to die from stealing a sip well under 30 mg, the (low) starting dose for an addict; while there are people on hundreds of milligrams of methadone per day. I’ve read of a case of a patient exceeding 800 mg of methadone daily. I doubt there even is a tolerance ceiling to opiates, just increasing side effects. So, one man’s poison is another’s painkiller.

Even when you do overdose, you can often fight to maintain consciousness and stay awake, at least for a while. But most deaths from so-called “heroin overdoses” aren’t caused by heroin at all. They’re usually caused by a combination of drugs, especially alcohol, which is such a toxic poison that it can kill you if you mix it with just about anything.

Did anyone at the Seattle Police Department look for possible signs that Kurt was unconscious before death? The telltale bluish-white skin and blue lips? Who knows if those signs would be observable three days after death, or noticed at all by ignorant, inept SPD investigators (who can be seen contaminating the crime scene in newly released photos), or even noticed by the doctor who performed the autopsy, who was an ex-concert promoter and friend of Courtney Love’s, and who probably didn’t conduct a very meticulous investigation. And if Kurt was given a hot shot, as Grant seems to allege, who placed his works, spoon, syringe, etc. back in the cigar box? Would a murderer do that? At the risk of leaving fingerprints? Unfortunately, the idiots at SPD probably didn’t bother checking any of the paraphernalia for prints. They didn’t even check the shotgun until the following month, and it had already been contaminated by the cop who handled it at the crime scene.

Basically, when you screw up an investigation, you invite conspiracy theories. But the idea of an instant, fatal overdose is far-fetched to say the least.

  1. Although I am by no means an expert on heroin (learning every day) I completely agree with your post and it’s something I keep telling people. Tolerance is an important factor that everyone seems to ignore. Add to that we don’t know when Kurt took the heroin. I hate that the SPD messed this up so badly. It’s innocent people like Frances and Cali that suffer the most.

    • Absolutely. Before I quit I could do about 100 dollars of scramble in a half hour without passing out. Keep in mind here in Baltimore the dope is scrambled with fetanyl, morphine or sometimes valium if it’s a shit batch. But the scramble is usually better than raw imo. Anyway, 2 full needles(I refuse to use slang, since only cops seem to use it ie “wheres your jammy” “that spike better not prick me” or “your fucking dead if your skag shooter is in your pocket”) and maybe a half shot depending on how much water you use. Ive seen guys shoot more and barely nod, so pressing a triggers shouldn’t be a problem. My personal theory (my uncle went out the same way) is he may have attempted to over dose and had the gun as a backup. Once he realized he wasn’t going out he pulled the trigger.


  2. Did you ever hear anything about him meeting up with Robert Downey Jr. the week before he died? I heard something about this before and the article was implying that Robert Downey Jr. might have sold him some bad drugs intentionally after he had a fling with Courtney Love..


    • No. It’s true he would take whatever he could get while travelling but Kurt was hanging out with junky friends at a restaurant in Seattle after he left Exodus (the L.A. rehab) and before he died. He was so high he couldn’t write the dinner check without help, but he was not OD’ing. So whether or not he scored before leaving L.A., he was publicly high on heroin and alive in Seattle before the end. His dealer was in Seattle anyway and he’d just left the rehab and hopped a plane home. It’s an amusing rumor, though. I’ve never heard it before.


  3. Heroin and methadone are not the same thing. Orally ingesting methadone does not produce the same effects as intravenously injecting heroin. Also, x milligrams of methadone does not equal x milligrams of heroin. To say that you have read of a patient exceeding 800 milligrams of methadone daily, just isn’t relevant. Not trying to be a jerk, but wanted to point this out.


    • I have also injected enough heroin at once to kill dozens of opioid naive individuals. All full agonist opioids create tolerance. Cross tolerance does apply to methadone and diamorphine. The sky is the limit with an opioid tolerance. Eventually you develop a tolerance to an amount that could kill dozens of opiate naive humans. It’s a simple fact. And the more heroin you can afford, the larger your tolerance is likely to be.
