De que murio realmente Michael Jackson?

Rumor has it that Michael Jackson may have overdosed on Demerol, an opioid pain medication similar to heroin. Demerol is synthetic (man-made) and is stronger than heroin, but it works the same way.

I have two questions. One is the timeline. I've read reports that MJ's breathing slowed very soon after he took the medication. This is all unconfirmed rumor at this point, but if any of it is true, there is the possibility that MJ didn't have to die.

Opiate overdoses lead the victim to stop breathing, but it doesn't cause cardiac arrest -- at least not until the victim has been not breathing for so long that his heart stops. If caught in time, simple mouth to mouth can keep a victim of opiate overdose alive long enough for paramedics to arrive and administer the antidote, a medication known as naloxone.

My second question has to do with Jackson's private doctor. The 911 call recording mentioned the doctor was with MJ. If this turns out to be related to Demerol, why didn't the doctor have naloxone available?

One thing to keep in mind: naloxone doesn't help after cardiac arrest. Once the victim loses a pulse, naloxone won't fix anything.

As with any celebrity death, there are bound to be lots of questions about Jackson's sudden death -- and his use of Demerol.
