[Drug trafficking and international law].

The production, the commerce and the use of drugs and other substances are ruled by several conventions of international law, that, at first, have had as object the production and the commerce of drugs for lawful purposes, and the measures required to prevent and to repress, at certain conditions, abuses and unlawful traffics. Just more recently, following some solicitations noticed by the International Community, and according to the concept of "well-balanced approach" described in the text, the measures introduced in this way were supported by a more incisive international movement, fit for the repression of unlawful traffics of drugs and to the adoption of suitable measures of prevention, also to avoid, at national level, sanitary, social and economical implications of the criminal phenomenon.
