I find similar little ziplock baggies in the beadwork section of our local hobby store...Hobby Lobby.

When I have to carry small supplies of prescription drugs I ask my pharmacist to print a second label, and I attach that to the baggie. I have not researched the actual laws, but the pharmacist assure me (FWIW) that the law actually refers to the "originally labeled" container...not exactly the container per se. This (second) original label serves the required purpose since it specifies the drug, the patient, the doctor, the pharmacy script #, etc. Clearly I'm legally entitled to be in possession of those drugs.

Again, FWIW, my larger FAK has several drugs so labeled... including morphine sulphate. It has "passed" TSA and police inspection without comment. But the drugs aren't stuffed in a pocket or luggage: they're clearly and obviously part of the meds section of a larger kit.

Certainly I am NOT entitled to dispense these drugs to anyone else. I figure that if I have to do so I'd probably welcome whomever came to arrest me because my party would be having an emergency. Take us to jail... Stop by the hospital.
