The top of the thread says "Ritalin good to snort?" Your answer, sir, is no. Smoke weed guy if at the least if you have to take it eat it dude like normal. Less bodily harm = having a better time later in your life.
Oxy's actually provides a rush when snorted as it can pass the BBB (blood brain barrier) in the nose. Amphetamine... not so sure i've never woke up in the morning and chopped up a line and said "DAMN I CAN'T WAIT TO GET FOCUSED!"
