[The French system of evaluation of dependence: establishment in a legal system].

The French system of evaluation of dependence has been defined in the French Public Health Code by decree 99-249 of 31 March 1999. It was created by health authorities 10 years earlier and concerns dependence and abuse, which were previously just submitted to control under the designation of non-conforming use and misuse. The consultative function of the narcotics and psychotropics commission has been reinforced and its mission extended to include evaluation. Cooperation with different actors has been organized. This is based on the complexity of the methods of evaluation and the impact of decisions concerning control and/or information. The same principles organize the cooperation of this system at the European and international levels.
