Adderall. New all time low? Or no big deal?

I'm not really the "druggie" type. I smoke weed daily before bed, sometimes for recreation, and drink occasionally (about once a month). But the past few days I've been using adderall xr 30 mg to stay awake and do homework/school. I didnt go to bed last night due to it, and I've been forced to again tonight, or I wont graduate! I'm not really sure what to think of my actions, is it pable since its for school? Or is this a new all time low for me?
