@Hlitner Thanks for your info. We don't take any narcotics but do take a controlled drug. My last cruise last year I tried finding out info from the countries we were going to and found some info was non existent. Even emailed the embassies and did not get a response from most. Spain, for one, did not respond. When I emailed again I got a response making it seem easy to send in paperwork and any questions don't hesitate to ask. I had a question and emailed back but never heard back from them. Ugh. That is probably one reason why some people take their chances.
The biggest thing for me is what happens in the worst case scenario if you are taken from the ship to a hospital in a country that does not allow your medication.
