A member asked:

Would vyvanse (lisdexamfetamine) and adderall xr have the same result on a drug test? is there any way a test could differentiate between the two?

Same result: Adderall is the active ingredient in Vyvanse (lisdexamfetamine). Mixed amphetamine salts show up on SAMHSA urine screens.
