Ritalin can be crushed and snorted for a high (I am told) that is indistinguishable from that of cocaine.
Adderall is basically dexedrine. Ritalin is another amphetamine. Speed - plain and simple. Back in the day - they were called “diet pills”, yellowjackets, black beauties, etc...
I once pulled an all nighter before finals with Nodoze and coffee. Even if I’d wanted speed - I never had the kid of cash required - I preferred to throw away my money at the Pub.
