So Oregon can permit assisted suicide, and it can permit these drugs in other applications, but it can't permit these drugs to be used for assisted suicide.
But the feds aren't prohibiting assisted suicide, because you said they can't do that. They are merely prohibiting an unintended and unapproved use of a drug, and that use just happens to be assisted suicide, but it's not the assisted suicide that's being prohibited, it's exactly HOW they are assisting suicide that's being prohibited.
And if they don't assist suicide just right, interstate commerce will be impeded, so this is not just the business of the state of Oregon, but it's a federal matter.
Have I got it right?
Correct.

Correct.

Using controlled substances in a manner for which they are not approved affect the safety and welfare of citizens. It would be both necessary and proper for Congress to legislate this activity if they so chose.
