Is health care a right or a privilege?

Today I had one of the saddest calls of my time here at cvfd. I was dispatched to a cardiac arrest. when I arrived I found this 18 year old kid lying on the floor in his room. My heart was already pounding from yelling directions to my third (new student on the volunteer) "grab the lucas, load the stretcher with the suction, lets go" I dropped to my knees and checked his pulse, and I started chest compressions. Before when I had preformed cpr it was always on 40-80 year old. But it was all for nothing, will one of the firefighters was starting to manage his airway but discovered the kid had rigor mortis. He had been dead for too long he was beyond help. Yesterday had been his 18th birthday. His room was filled with empty rum/beer bottles and there was a bag weed, I am not sure how he died but this wasnt a one time event, Actually last week my dept. had responded to this same kid crashing a car into a house completely drunk. No matter what he did or had done with his life it was just a horrible experience, I am not sure which was worse, leaving his cold body on the cement floor or walking past his mother outside the house.
The whole experience brought me back to a debate I had earlier with my friend about whether health care is a right or a privilege. It seems self evident to me that health care should be a right for everyone. But when people deliberately throw away there life repeatedly what do you do. Do you get so many chances? Or is addiction just as much a disease as cancer and just requires treatment through lapses and remissions. But there is an undeniable element of choice in these cases. So where is the line? Is there one?
