NO WAY, those are horrible to snort....it's impossible to get it to a powder consistency...just get that plastic thing off of them and chop it with a knife into 4 or 5 pieces and try to grind that...get it as ground up and processed as you can...it will work but you have to break up the many layers of time release...plus you probably have a super tolerance to those things, taking them for 7 years, wowsers...ask your doctor about switching you to adderall maybe, just say the concerta isn't doing its job anymore
