Yeah well, here the problem was, imo, a bad doctor. There would've been plenty ways to give the same effect without compounding the abuse from a single drug.
It's not like you administer propofol for yourself. But the social dynamic between a celebrity that famous and anyone who isn't would ofc be different from regular patients. And propofol doesn't exactly have a large abuser base, which would've made it easier to avoid a fatal dose..
But anyway...
