Thre is no way to tell when or if you will blow a hole in your mucosal lining...but as long as you snort a drug like that...u r running that risk
I concur with worried - the mucosal lining is very easily damaged. And there's not much between that lining and the cartilage in your nose. It doesn't take much to do some serious, long-lasting damage.
In the absence of any available information about snorting Adderall, I would tend to the side of being very cautious.
