Not sure what your point is, there is drug smuggling in pretty much any country in the world (except maybe North Korea), this can not be 100% stopped. By now it is common knowledge that western european ports are the drug hubs of the EU[1].
The whole border surveillance system went down in order for drug shipments (and who knows what else) to go through. The problem is obvious, you just need to acknowledge it.
There's a difference between 1) insufficient border protection and 2) corrupt border security.
