Crush that shit into a fine powder and bomb it. Believe me it hits harder when parachuted, I use to snort adderall daily as a teenager. Then I realized it is more effective bombed. But if you want to get fancy and get the most bang for your buck, rectal is the supreme ROA for adderall. It's not difficult to do: Crush the pill(s) in a bevel-bottomed shotglass.
Add 7-9ml of warm water into a 10ml oral syringe (the remaining space will be taken up by the pills' binders, depending on how many you use).
Draw up solution, paying special attention to the liquid portion of it, as amphetamine is highly soluble in water. Residual binders left in the bottom are unlikely to provide additional benefit, but get 'em if you can.
Lubricate syringe
Insert'n'squirt
Remain on left side for between 5 and 15 minutes.
