Im grenzüberschreitenden Warenverkehr (v.a. Reiseverkehr o. Postverkehr) liegt die Aufmerksamkeit bei der Kontrolle von Tieren oder Pflanzen auf der Einfuhr von exotischen Exemplaren, die dem Washingtoner Artenschutzübereinkommen CITES (Convention on the International Trade in Endangered...

Narcotic drugs are smuggled from the Americas to Europe and many parts of the World. While opium, cannabis, hashish or other drugs are mainly coming out of Asia or Africa and are channelled and smuggled to Europe mostly on a land passage (or very short maritime routes), cocaine is mostly...
