Will adderall and Vyvanse show up the same in a drug test?

Yes they will, but they will show up as the same thing...amphetamine.

It depends on the type of test. It will test as an amphetamine on a base level test but an professional panel test can distinguish the difference because Vyvance only uses the D-amphetamine. Adderall uses four different types of amphetamines. So they can test by the presence or lack there of to determine. Virtually all drugs leave a unique footprint behind.
