Abstract
Relations between drugs and international trade are a long story, we could think of the 19th century and the important consumption of opium in Europe, as can be seen for example in the film From Hell. Opium was obviously not produced in Europe for climatic reasons and essentially came from Asia. Drugs have long been trans-national goods. Nowadays drugs still are a major issue in the society but consumption and production structures have evolved and are still evolving. Drug trade is linked to borders, money circulation and easy traveling. All these areas also concern globalization. A simple definition of "drugs" could be: psycho-active substances. Nevertheless it is more complex because some products are legal in some countries and not in others. On the one hand, tobacco and alcohol are legal psycho-active substances in most countries.
