    Duration of Detectable Methamphetamine and Amphetamine Excretion in Urine after Controlled Oral Administration of Methamphetamine to Humans

    From the abstract:

    The object of this study was to characterize the urinary excretion of MAMP and its major active metabolite, AMP, in humans after controlled oral administration. Urine concentration data were evaluated to determine detection windows and confirmation rates based on current and proposed confirmation cutoffs and cutoffs based on MAMP requirements alone.
