Terminally ill does not mean “might die.” It means, legally, that the illness has no real chance of being cured by known treatments.

So, something like late-stage cancer or ALS.

Also, I think you misunderstand how these laws work. It does not give the patient the right to compel a doctor prescribe them any treatment they want.

It gives the patient a right to try experimental drugs that have not been authorized by the FDA. That’s pretty much it. It doesn’t guarantee them access to the drug, only that they’re allowed to try it if they can find it.

You have the right to try an experimental drug, but you still have to find a legally-authorized party to be willing to give it to you.
