Dr. Regina McQuillan:

A very important point that goes beyond the prescription of drugs is that Dignitas requires a letter from a doctor stating that a patient has a serious illness. That is a much more fundamental and worrying way in which doctors are involved. One could argue that in the case of a judicial execution the person who prescribes the drugs is not the executioner. However, in centres such as those run by Dignitas in Switzerland, health care involvement is required in respect of a diagnosis being made. It is a very serious risk to health care that one is required to make diagnoses to facilitate assisted suicide or euthanasia.
