sure, snort away, but good fucking luck having it do anything. concerta IS ritalin, a pretty high dosage for one pill, i think something like 35mg. but it is a time release ritalin. and i have disected it every which way and couldn't find a way to get high off snorting it. it is really weird, with seperate sections inside the pill. if i remember correctly part of it is a dry grey material, than another part is yellow and not as dry, and a small part is white. i have crushed up each part and snorted them seperately and together in every combination and it didn't do anything. don't know why though.
eating eat will do something, probably not much, but will last for a long time. perfectly safe to drink alcohol with.
peace, outkast
