I know that Adderall is an amphetamine but he categories listed on the test are THC, Opiates, Oxycodone, Methamphetamine, and MDMA. Also, how long AFTER use does it take for it to show up in my urine? (ex. say i took one RIGHT now, will my next piss come up positive?)Many thanks to everybody who answers, but please give an educated answer, not just a guess.
