ADD meds are among the few pills I saw are alright to snort, it gives an extra rush. You have the break the little balls up very well though and go over it with a razor the best you can. When you snort them they wont last as long, its stronger and you don't need as many pills. If they are Ritalin SR the drug is released into your body slowly (Sustained Release), breaking the little balls in the capsule up will break the sustain-release mechanism as well. You could also just crush and take orally, start with 30-50mg if you're going to do this.
