I've been prescribed concerta 54mg for about a year now, and I know aboutall the layers and abuse potential. Now I've been switched to generic concerta(didn't even know this was legal in the US) and I'm wondering how exactly this pill works, as in its mechanisms, effectiveness, abuse potential/risks, ect. For instance if I crushe the pill I get a mostly white powder. Is this white powder safe to snort or do anything else with perhaps? Are there any defense mechanisms I should know about if I were to abuse this? I can't find and information on it.
