Adsorption of MDMA in vitro. Serum containing 3,4-methylenedioxymethamphetamine (MDMA-FCS, 1 μg/ml) was circulated from a reservoir at a flow rate of 170 ml/min (a). MDMA-FCS samples were taken from the circuit before (pre, red) and after (post, blue) the adsorber device at 0, 5, 10, 15, 30, and 60 min, and MDMA was quantified by HPLC (b). Dashed line indicates calculated half-life
