The CSA obviously limits the prescription of drugs in lethal quantities. One state's vote to allow assisted suicide does not overturn a federal law. This isn't a novel principle. In the California cannabis case, the Reno Justice Department fought for the federal law. He said California's marijuana initiative is irrelevant.
Federal law supersedes state law.
Because Oregon Democratic Sen. Ron Wyden put pressure on Democratic Atty. Gen. Janet Reno. This directly applies to the alienation of life itself by assisted suicide. You applauded Lincoln's interpretation of the Declaration then on the alienation of liberty but have disregarded its application to the current issue of the alienation of life itself.
