How long Concerta urine?

never u mind Addition to "never you mind." "Never you mind" is a good answer if the person asking the question is looking to cover the use of unprescribed Concerta - i.e., drug abuse, the unlawful use of a controlled substance you do not want the DEA (or your employer, your coach, your local law enforcement, your fill-in-the-blank) to discover. But, unfortunately, there is a legitimate need for the information requested. I am spending hours evaluating a similar question - how long must a mid-teen be off a 45 mg/day prescription to pass an in-competition drug test by the US Anti-Doping Agency. Concerta is approved for out-of-competition use by the USADA. It appears to be approved for regular season, but not playoff or championship use, by the NCAA. But it is banned for in-competition use by the USADA and for NCAA post-season competitions. So how long before a drug-testing competition does a mid-teen (or other person) go off prescription meds, which their medical provider has determined are needed to facilitate "normal" functioning, to avoid disqualification? I have found answers ranging from 1 to 90 days, depending on testing protocals and other factors. I have even sent an email to the USADA asking if it is aware of resources we can look at. I hope somebody smarter than me provides a better answer to this question, even though its use by drug-abusers is easy to foresee.
