its from both..i take adderall rectally at all times. it kicks in within 3-5 mins, and hits me pretty hard like bricks, it still gives u all the positive effects of taking it orally, and for me, i feel plugging adderall makes the high last so much longer..after redosing and plugging, within 60seconds i get an intense hot flash followed by extreme euphoria..its amazing, but orally works awesome too. i learned that taking benzos for an adderall comedown is a total waste, #1 because once the benzos wear off i go back to the crash and feeling miserable, i rather take a trazadone or seroquel when im crashing and let it knock my lights out, instead of taking a benzo and going to sleep right after..also since my body is so hpyertensive i need like 2-3x more benzos then my body normally needs to calm down.
