Abstract: New psychoactive substances of phenethylamines are the third synthetic drugs in the world, which have the dual effects of excitement and hallucination. The structure of this type of substance is unpredictable, and a series of compounds such as 2C, amphetamines, DOX, NBOMe, and FLY have been derived through structural modification. They are far more harmful than traditional drugs and seriously threaten individual health and public safety. With the continuous changes in the structure of new psychoactive substances of phenethylamines, more and more attention has been paid to the metabolism of these substances. The application of various in vivo and in vitro metabolism models and liquid chromatography-high resolution mass spectrometry has gradually clarified the metabolic process of new psychoactive substances of phenethylamines in human body, which has greatly enriched the metabolic data of these substances. The biotransformation reactions involved mainly include oxidative deamination, O-demethylation, N-acetylation, hydroxylation and so on. This article reviews the structure, classification and related metabolic models, metabolite analysis methods, and metabolites identification of new psychoactive substances of phenethylamines, in order to provide basic data for the abuse monitoring of these substances.
