i was wondering if mdma shows up (for a normal pre-emp job test) because i know amphetamines (adderall, meth) show up and mdma is methylenedioxymethamphetame. On the other hand, i have heard that it doesn't but i don't know b/c that guy who told me that is half my weight and he drank a couple gallons of water. I will not do that b/c everytime i tried just drinking 1 gallon i puked it up. Plus it's very unpleasant.
depends on how much you take and the extent of the time period, BUT 2-3 days max is how long itll stay in the system.
