I mentioned this in a reply below, but I'm an American who lived in Croatia for a little over a year. I lived there with a few other Americans. I'm not sure if any of this is true, but we were told Croatia has very strict anti-drug laws. We were told that if we were caught with any amount of drugs whatsoever we would be instantly deported, no questions asked. I wasn't sure if it was a "you better not do it" exaggeration warning or it was truth. Either way, once a police officer stopped a few other Americans I was living with on the street out of the blue and flat out asked them if they were carrying any drugs. I wasn't with them at the time, I only heard the story when they got home. They were obvious foreigners because they were speaking English to each other while walking down the street. I believe the officer also checked everyone's IDs and the papers we had to carry that showed we registered our address with the local police. Yes, as foreigners staying in Croatia we had to register with the local police.
