We report on a 16-year-old body builder who suffered from an acute ischemic stroke. In the urine, cannabis metabolites as well as metabolites of the oral androgenic-anabolic steroid methandrostenolone were detected, both known to be associated with stroke events. This report highlights the role of cannabis and steroid abuse that induce strokes in the absence of arteriopathy, cardioembolism or thrombophilia. Owing to new upcoming socio-behavioral aspects of late childhood and early adolescent life, this formally rare abuse of cannabis and/or anabolic steroids as well as their associations with strokes becomes more current than ever.
