Let the hive mind of Engadget get that for you.
"I'm looking for a pair of quality headphones that aren't seemingly made of glass. I'm an avid BMXer which causes me to frequently bash on any type of technology that joins me for my daily riding. I've been through the higher quality headsets in the Skullcandy line as these are supposed to be built for "abuse," which is laughable. I cant wear earbuds or canal buds, as my large ears seem to have a repelling property upon anything that sits in them. Wired or Bluetooth doesn't really matter, but I need something that can hold up to taking a few hits every now and again. I'm trying to keep 'em under $150. Thanks!"
In a hospital--with proper equipment, and with an anesthesiologist monitoring the situation--Propofol can be safe. But it's intended to be used only once: to keep the patient asleep during an uncomfortable or painful procedure.
According to a story I read in the UK press, Jackson used an IV drip of Propofol to sleep: nearly every single night. It was only a matter of time before it killed him.
Usually, abusers of Propofol are medical professionals (because only they have access to it). MJ however had the resources to hire personal physicians.
Sadly it's not unusual for starstruck doctors--eager to become part of a celebrity's entourage--to become enablers of addiction. MJ's doctor ought to lose his license. Whether he's criminally negligible? The courts will have to decide.
Despite Propofol abuse being fairly rare, studies have been done on it. Among those who feel drawn to use it over and over again, most have had childhood trauma. These are people who've suffered with nightmares and flashbacks all their lives. They're desperate for sleep, and oblivion.
Carrying such a load of emotional pain, these folks are at high risk for self-destructive behavior. If they didn't turn to Propofol, it'd be something else.
Jackson bears some responsibility (we know he begged doctors for it). But a responsible doctor would not have agreed to give him the drug...certainly not repeatedly.
