so i'm about to try out adderall, which from everything i've read is pretty much speed, and i was wondering which one, XR or IR, has the better effects? i was planning on snorting it, so i thought that XR might be better because of the little balls that you can just crush up into powder. but, i heard that it takes a while to set in and that IR is stronger and fast reacting, but the the only problem is its a tablet, i don't know, thoughts and opinions please, thanks a lot.
