i think snorting that sticky clumpy powder is a pain in the ass... concerta itself is a pain in the ass to use recreationally or even productively, but obviously it can be done. the way i found best to use them is to put all the methylphenidate containing material into a cup of coffee, prepared however you wish to drink it, and drink that pretty quickly... i normally continue to drink coffee and do whatever is planned (normally a tedious task like cleaning my room); it is reasonably effective, but obtaining a better form of speed is much more reliable.
