Regulatory action by government authorities seeks to monitor and legislate on production, trafficking and consumption by the population. This approach implies a constant updating of information, namely regarding the existence of New Psychoactive Substances, analytical methods for the identification of products and detection procedures in biological samples, in order to assess the clinical effect of the substances on the individual, both at a physical and psychoactive level. In this presentation, these themes will be addressed, with emphasis on the applied analytical methodologies, the challenges associated with the Medico-Legal interpretation of the results obtained and the transposition to a legislation that needs to be both dynamic and up-to-date.engNPSForensic Toxicologyconference object
