Blood these days (is in early stages) of being lab manufactured. Got family that are firmly in the blood "industry".
Blood is also different to organs because organs are in lower supply than blood reserves (which can actually get transported across the globe - unlike organs which have a lower half life).
The way I see it, if you've abused your body or are not willing to share your organs with others why should you benefit from a healthy organ that's donated.
I'd go furthur and cut off medical services to those that don't take treatment seriously.
@ASSASSIN (given his hospital visits and surgeries can probably back me up here), but the number of people you see outside (for example) Blacktown Hospital on a chemo machine or other drip, near the carpark, puffing down cigarettes is astounding. Now sorry, but if you arent' going to take your treatment and recovery seriously, disconnect the IV lines, send their arse home, and give the bed to someone who will take it seriously.
I was visiting Blacktown for over a month almost daily earlier this year and you'd often see 5 odd at any time smoking away.

What will be interesting is they are currently in first stages of growing organs on other animals and just recently transplanted (I'd have to look it up), but from memory it was a heart grown on a pig, into a monkey.

Can I throw another situation your way for thought
@Sleeky?
Lets say the person is NOT an organ donor. They get a new heart transplanted and then weeks later they die from an unrelated issue (lets say car crash). The transplanted heart they got is still viable (as are their lungs). However because of red tape nad opting out, theres not only a healthy heart from a donor, but other organs now left to rot.

@CroydonDog Re the money side of things, rather than money for organs, why not offer $500 off a funeral or something (government rebate) if the person is a donor, and $1000 off if it's a cremation.
