Abstract(s)
O mercado das Novas Substâncias Psicoativas (NSP) tem vindo a desenvolver-se
rapidamente, sendo caraterizado por uma grande variedade de substâncias baratas, potentes
e facilmente modificáveis. Estas substâncias podem ser compradas online, ser
transportadas através da União Europeia (UE) e entregues aos consumidores por correio ou
serviços especializados de encomendas, criando novos desafios para sua deteção e
monitorização. Em Portugal, o consumo das NSP tem aumentado nos últimos anos. Estas
substâncias não são detetadas através dos habituais testes de identificação e despiste de
drogas, não se encontrando disponíveis testes específicos, direcionados exclusivamente
para as NSP e para as drogas sintéticas, dificultando bastante a ação policial. Foi efetuada
uma análise às potencialidades da espetroscopia de Raman, tendo ficado demonstrado
objetivamente que é uma técnica viável e credível para a identificação presuntiva deste tipo
de substâncias. Face à legislação atual, a despistagem de NSP e de drogas sintéticas através
da técnica de Raman pode ser considerada válida, uma vez que a legislação não especifica
ou determina qual o tipo de teste a utilizar nos despistes. Contudo, a prova pericial é
sempre a que resulta do exame laboratorial realizado a estas substâncias.
The market for New Psychoactive Substances (NPS) is developing rapidly and is characterized by a wide variety of cheap, potent and easily modifiable substances. These substances can be bought online, transported across the European Union (EU) and delivered to consumers by mail or specialized parcel services, creating new challenges for their detection and monitoring. In Portugal, the consumption of NPS has increased in recent years. These substances are not detected through the usual drug identification and screening tests and no specific tests exclusively targeting NPS and synthetic drugs are available, making police action very difficult. An analysis of the potential of Raman spectroscopy was carried out, and it was objectively demonstrated that it is a viable and credible technique for the presumptive identification of this type of substances. Under the current legislation, the screening for NPS and synthetic drugs using Raman spectroscopy can be considered valid, since the legislation does not specify or determine which type of test should be used in the screening. However, the expert evidence is always that which results from the laboratory examination performed on these substances.
