Determination of cathinones and other stimulant, psychedelic, and dissociative designer drugs in real hair samples.

The detection of new psychoactive substances (NPS) in hair proved to provide insight into their current diffusion among the population and the social characteristics of these synthetic drugs' users. Therefore, a UHPLC-MS/MS method was developed in order to determine 31 stimulant and psychedelic substituted phenethylamines, and dissociative drugs in hair samples. The method proved to be simple, fast, specific, and sensitive.
