Daniel hit a wall trying to travel with his Vyvanse prescription — and it turns out the problem isn't just Japan's strict drug laws. It's that every piece of the puzzle exists, but nobody's connected them. In this episode, we unpack what an international health card would actually require: global prescription records, real-time drug legality databases, doctor verification, and insurance interoperability. We explore why the CDC Yellow Book is just a PDF, why the EHIC is only a billing shortcut, and why the liability, privacy, and incentive problems may be bigger than the technical ones.
