if they are in a little plastic capsule in tiny little balls, take them both orally like 10 minutes apart... if they're just the coated straight form of adderall, crush em up and snort them in small lines

they'll last much longer when taken orally but they will hit you much harder snorting them. snorting them also leaves me with a terrible terrible comedown and taking htem orally does not, but that's just me
