IntroductionNovel psychoactive drugs (NPS) has rapidly increase in the last years in the drug market as a recreational use. Fenethylline is a theophylline, an amphetamine-like drug, having stimulant effects similar to those of other amphetamine-type derivatives. Fenethylline was used as medicament for hyperactivity disorders in children, narcolepsy and depression, but it has also been used as a drug of abuse under the common name of ‘captagon’. The purpose of this report is to review the clinical evidence for the potential of abuse of fenethylline. We propose a case report and literature review.MethodWe conducted a systematic review of the literature with the principal database (PubMed, Enbase, PsychInfo) and we present a case report.ResultsThe effects of fenethylline is characterized by euphoria, derealization, autopsychic and somatopsychic depersonalization, hallucination, agitation and decrease of pain perception.Discussion and conclusionThe primary drug market for fenethyline (as captagon) has traditionally been countries located on the Arabian Peninsula but also North Africa since 2013. To our knowledge, there is no report on the recreational use of fenethylline in literature. The clinical features of fenethylline intoxication were also similar to effects from other amphetamine-like drugs. In our case report, dissociative symptoms are the core of fenethylline intoxication. Further research is warranted to replicate our clinical and qualitative observations and, in general, quantitative studies in large samples followed-up over time are needed. Methodological limitations, clinical implications and suggestions for future research directions are considered [1,2].Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionNovel psychoactive drugs (NPS) have rapidly increase in the last years in the drug market as a recreational use. A new group of toxic phenethylamine derivates named NBOMe of 2 C class present have emerged recently, are frequently bought using the internet and have similar effects to other hallucinogenic drugs; however, they may pose larger risks, due to the limited knowledge about them, their relatively low price and availability via the internet. The purpose of this report is to review the clinical evidence for the potential of abuse of NBOMe compounds. We propose a case report and literature review.MethodWe conducted a systematic review of the literature with the principal database (PubMed, Enbase, PsychInfo) and we present a case report.ResultsThe effects of 25C-NBOMe is characterized by hallucination, violent agitation, rhabdomyolysis and kydney injury.Discussion and conclusionEffects from 25C-NBOMe in our case report were similar to previous individual case reports in literature. The clinical features were also similar to effects from other analogues in the class (25I-NBOMe, 25B-NBOMe). In our case, violent agitation (signs of serotonergic stimulation), rhabdomyolysis and kidney injury were observed. Further research is warranted to replicate our clinical and qualitative observations and, in general, quantitative studies in large samples followed up over time are needed. Methodological limitations, clinical implications and suggestions for future research directions are considered.Disclosure of interestThe authors have not supplied their declaration of competing interest.
