I know this is a late response, but I just had to reply. I took Adderall for about a year when I was 18 and I literally could not stop picking at my face. I would sit in front of the mirror for hours and pick at every pore until my whole face would be bleeding and scabbed. In my mind, I was striving for perfection by getting rid of any blackheads, but in reality, I was scarring my face for years to come. I think that being a young woman and obsessing over appearance has a lot to do with it. But I also believe that the Adderall played a major role in it. I was taking too much and would be so awake and impatient that I would sometimes pick at my face because there were no other tasks or activities that were as seemingly instantly gratifying. I would talk to your daughter and make sure that she is taking her prescribed dose, or maybe allow her to see a therapist or counselor once a week or so to get to the real root of her problems. Ever since I lowered my dose and then, eventually, stopped taking the Adderall, I have much more control and can stop myself when I begin to pick.

Best of luck.
