He does not. I feel that if someone has the right to defend their life, there's no way you can say they have no right to control their death, especially if they have degenerative disease, or there's a disease with no hope of recovery and they feel they are instead a burden to not only their family but to society.
Spending months on end on a ventilator, IMHO, is not a way to die. Getting pumped with morphine after 6 back-to-back heart attacks, a brain aneurysm, and developing a systemic infection, IMHO, is not the way to die.
Therefor I do support it. I do not have the amount of clinical experience Dr. Paul does, but after spending a good amount of time in the back of am ambulance and doing many rounds in the ED department of a major hospital... I definitely think it's something many don't understand until they see a patient begging for "mercy."
