No.  Think about it for a minute, not from the view of the person killing themselves but from the view of the doctor.  Over 50% of people who see death outside of war have suicidal thoughts.  So if you put a doctor, especially an ER doctor or nurse, who see death already on a day to day basis, in the position of having to kill you or someone else, how would they feel.  The physician's job is to preserve life not end it.  If you start having physicians kill people, it will demoralize them when the one thing they stand (preserving life) is the one thing that they are stabbing in the back.  If physician assisted suicide is legalized, physicians will be influenced by the deaths that they see but also the deaths that they cause.  This will tip them over the edge towards suicide.  Eventually, doctors will be killing doctors who killed doctors who helped people kill themselves.  Had those people not gotten the doctor to help them commit suicide, said doctors would not be going to see other doctors to commit suicide in the first place.  Additionally, the suicidal tendencies typically do not emerge for up to 10-15 years.  The states like oregon that have allowed PAS will not see this result for up to 10 years from now and by the time that they see the result, it will be too late to stop it.
