When did I say my father was in MA? I live in MA. He doesn't. And I didn't say he prescribed anything for me. I said that when he retired, his state board provided him with a limited license that allows him to write prescriptions for family members only. At no time did I claim that he wrote any prescriptions for me, or any family member. I said that he COULD. That he was legally permitted to. That the state did not tell him he was prohibited from writing scripts for his family (as you insisted that was the case); that rather, the state ONLY allows him to write for family members now that he has retired.
You were insisting that a doctor is prohibited from writing any kind of script for a family member, and I told you you were wrong. Which you are. At best you've shown that maybe your wife could not have written you certain medications in one state. You have not shown either of your other contentions (that a doctor CANNOT write scripts for family members, or that a doctor cannot write prescriptions outside his/her own specialty) is correct.
You clearly still do not understand that nowhere are you going to find laws that give permission for an optional action. In the absence of a law prohibiting an action, the action is legal. So I don't have to show you any laws saying it's permissible - you have to show the laws that say it's not.
