my sis who is a pill popping, junk food junkie has had a large amount of surgery to fix what she has broken, and she remain non-compliant with medical care. The MDs have all told her that they are going to find her "dead in bed' if she doesnt wake up and start making better choices. To me, its the same as putting a gun to her head, but it just allows her to do it in slow motion and cause a great deal of suffering to others along the way.

The only thing I can see as a "passive" suicide is if you make arrangements with an MD ahead of time to continue to pump the pain meds at you, even if it hampers your ability to breathe, and hastens your death.
