I think the word “euthanasia” should be left out of the whole thing. Legalize state-assisted suicide for everyone of legal age. Make this euthanasia substance available through psychiatric institutions and clinics by prescription only. Anyone who is not clinically depressed may go to the clinic to be evaluated, and if in their sane and non-depressed mind, they wish to go through the process of suicide certification, they may. Also, the drug should not harm the organs, and organ donation should be mandatory. The process should be informed consent, a 5 day waiting period in which you receive counseling, and a fee for handling the (remains of the harvested) body.
The process may be terminated at any time by the counselor or the patient. If the counselor finds the patient non-sane or depressed, the procedure is terminated. If the patient changes his or her mind at any point between application and the actual injection, the procedure is terminated. No family, friends, or anyone else other than the actual individual, through completing this process (which can/would include a living will and situational cancellation clauses), may make this decision in regards to any other human being. Family, friends, and other individuals will not be permitted to participate in the counseling session, or have contact during the counseling period. Children, teens included, are not considered to be eligible for the suicide program.
Once the entire process has been gone through, one is sure, and one has received their “certificate of authorized suicide”, then one may make one’s death plan. One’s death plan is the circumstance under which you wish to administer your injection, or have a certified professional administer your injection. Family members, friends, and other witnesses may not administer the dosage. Death should be permitted at home, at hospice, in hospital, or other public or private location approved for the purpose. (We could have a whole new industry! “Die at Mount Vernon! Follow in the footsteps of Presidents!” It’s already used for weddings, baptisms, and other parties.) Organ harvesting ambulances will be standing by. The injection itself; the state/federal/government counseling; and a basic living will, if desired, is free. The ambulance for the body is free. Everything else can be any way you pay for it to be.
Killing a certified suicide still counts as murder. Legal status of the individual does not change. If they become insane or depressed at a later time, but have a living will or death plan in place, the certification for suicide remains, as long as the living will or the death plan indicate so. If they are diagnosed as depressed or insane without a living will or death plan, then the certification for suicide is revoked, and the process must be restarted from the beginning. Attempting suicide in any form other than this one should be illegal, and require psychiatric attention. Anyone who has ever attempted an illegal suicide (once above the legal age, since we shouldn’t hold children’s foibles against them) should be ineligible for the program. I’m sure I’m missing something important, but this is a good starting point.
