My new doctor cancelled the refills on the prescription my old doctor gave me. Is this legal?

Yes, it is legal. As a patient, you don't decide which prescriptions you need. Your doctor does that. Otherwise, you could have multiple prescriptions from multiple doctors, and they're on to that scam. There's a term for it: Doctor shopping.

Yes. He obviously feels that it should not be refilled. That is his right - he's the doctor.

Not only legal, but STANDARD practice.

Yes.

yes cause he is your new doctor

Sually they have an expiration.

Of course

He is the one who is allegedly supervising your treatment.

Yep, totally.

You're not legally entitled to drugs. If your new doctor thinks the prescription is not in your best interest, he/she can cancel them. And if you go in there jonesing for a hit of that drug, guess what, they made the right call, because you're an addict.

Yes
