Comment on: An Insight Into Z-Drug Abuse and Dependence: An Examination of Reports to the European Medicines Agency Database of Suspected Adverse Drug Reactions

After the publication of an article discussing the methodological options to detect the diversion potential of prescription drugs, this letter presents the multidimensional functioning of the French Addictovigilance System. This system aims at monitoring all substances with abuse potential, relying on a network of experts specialized in clinical and fundamental pharmacology. For more than 25 years, we have created collaborations with partners at the interface with field data related to substance use and the potential related disorders. When relevant depending on the context, these data sources are explored and crossed to analyze the abuse potential of one given substance. This organizational approach is useful to detect early Addictovigilance warning signals and to take appropriate measures. Generalizing such a multidimensional approach outside France appears an appealing option to move towards more effective Addictovigilance systems at the international level.
