A member asked:
Is there any type of drug test out there that can determine if someone took adderall vs. vyvanse (lisdexamfetamine)? or will they all just tell you amphetamine?
12 doctors weighed in across 3 answers
Not from what I hear: Perhaps someone knows otherwise - but I've never heard that they can discriminate between amphetamines. Good luck.

No: Adderall is a mixture of 4 different forms of amphetamine. Vyvanse (lisdexamfetamine) is just dexedrine sullfate. It will not be possible to distinguish them.
