Indirect euthanasia methods include an individual taking the final step to killing her or himself.  Mostly it is when the patient gives the physician the right to kill them when there are too ill to kill them selves.  This type of euthanasia is legal in certain states of the United States of America.

The direct euthanasia method is when someone else does the final step of death, such as a physician or a nurse, by administering a lethal drug by injection, such as in the Morrison case.

Voluntary euthanasia with full knowledge of the patient and the physician that the victim wants to die once he or she are not capable to perform euthanasia them selves, like Sue Rodriguez who had Lou Gehrig’s disease.

Non-voluntary euthanasia without the full knowledge, the patient wants to die but does not know when the physician will inject him with drugs to till him.
