Dunno, but it got to be there are some border check. It seem I could bring tons of heroin to EU very easy.
Oh yeah? I seriously hope you try lol.
Get an actual metric tonne of heroin across the continent of Europe, and post your results from an international prison.

I'm sure you realize how easy it is to just type words about how easy it would've been for them to prevent this if they just did border checks? What are border checks? Checking to see if the borders are still letting people through like they're supposed to be? Have you heard about the refugee crisis in Europe? Do they just close the borders and let the millions who AREN'T going to strap on suicide vests in downtown Paris just be told to go home?
Or do you seriously think they have the time and resources to stop and frisk every single person who gets off an airplane, drives across in their car, or is stuck in a refugee camp just outside of a city? Come on man, these things just aren't plausible when you consider how many people they have would have to deal with every second if they don't want anyone sitting around in a country for years without being able to legally or afford get a job, license, car, house.
