Exactly. In order for a patient to be able to even request physician assisted suicide, they have to have been diagnosed with a terminal illness, have had a diagnosis from 3 different doctors stating that they will live no longer than 6 months, and that the 6 months they will be alive will be excrutiatingly painful. Likewise, the request for PAS must be submitted 3 separate times prior to granting the request, to insure that the patient is not acting on a whim. If the request is granted, the physician can only prescribe the necessary medication. The patient must be capable of taking this medication by their own hand. They must also undergo an extensive psychological examination showing that they are fully aware of what they are requesting.
In fact, most patients who even request PAS end up dying from their illness before the process of request can be completed.
