Amphetamine Abuse

For two years I took an average of 140 mg of Adderall a day, about four days a week. Over the last six months of this, my nose bleeds every time I took it, even if I take it orally, not blowing it. Does anyone know why this might be happening? And are there any long term effects of this kind of abuse of amphetamines, even if I'm doing without medical crisis? Thank you all. :)

with amphetamines make you mad, but you think your hahaha quite normal, until you give it and after a long period, you realize that crazy after all.
