    We report a case of intoxication by the synthetic cannabinoid MAM-2201 ([1-(5-fluoropentyl)-1H-indol-3-yl](4-methyl-1-naphthalenyl)-methanone). A 31-year-old man smoked about 300mg of a herbal blend. He experienced an acute transient psychotic state with agitation, aggression, anxiety, and vomiting associated with a sympathomimetic syndrome. MAM-2201 was detected and quantified in a plasma sample using liquid chromatography-tandem mass spectrometry (LC-MS-MS). The level was 49ng/ml 1h after smoking. The use of other drugs was analytically excluded. The presence of MAM-2201 was confirmed in the herbal blend using gas chromatography-mass spectrometry (GC-MS) and LC-high resolution MS. This is the first description of an analytically confirmed intoxication and of the determination of MAM-2201 in human blood plasma
