> Do you think MDMA just breaks down completely devoid of methamphetamine as a metabolite?
AFAICT, that is correct; why do you think it doesn't? Name-based intuition?
Every reference, paper, etc., I can find of MDMA metabolites does not identify N-methylamphetamine (“methamphetamine”) as a metabolite of MDMA, and every identified metabolite retains the two oxygens of the methylenedioxy unit (whether it retains the whole unit or not) that distinguishes MDMA from methamphetamine.
