how long does adhd medication stay in your urine?

Answer 1

This depends on many factors:
how long have you been taking it
which medication you are taking (there are many!)
what dosage are you taking
how many doses a day

If you are taking this legally, with a prescription, you have nothing to fear. Take the prescription bottle with you to the testing.

If you are taking it illegally to get high, you are probably cooked since you would need a minimum of a month to test clean for most of the medications.
