its for add, its the shit!! i tried to get some but ended up with concerta, which made me feel like a crazy person. i always got some from other add kids for exams...id mysteriously know shit that i didnt know before! it creates a nice sense of calm, and you can focus really good...it would be perfect for a quilter or something, it makes you creative and lasts for a good while. i always got really friendly when i took it too.
take that shit away from her though and have a talk, cause in my experience only drug addicts (well not addicts, but users) get a hold of pills they arent prescribed to...good luck
