I've been on a rather astounding Adderall binge lately whereby I put fairly large doses (though sometimes upwards of 60mg at a time) into my nose. This post was partially inspired by a short spurt of paranoia earlier after managing to cram 12 20mg IR's up there over the course of about 8 hours. Disregarding how awesome that felt, it made me curious as to what I should limit myself to over a given period of time, say 12 hours. 'Cause although being young and healthy (for the most part) keeps me optimistic, I would in no way want to risk permanent health effects simply due to my abundance of money and outstanding Adderall hookup.
