A member asked:

If i fail a ua for amphetamines because i've been taking vyvanse (lisdexamfetamine) without a perscription, will they be able to conform i was only using vyvanse (lisdexamfetamine)?

A doctor has provided 1 answer

Probably not: Drug screens show up generic amphetamines. It will just show up as amphetamine on drug screen. Please do not take amphetamines with a prescription. It could be very dangerous.

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?

A member asked:

Why would I be unaffected by amphetamines despite not having a history of usage or abuse? Vyvanse (lisdexamfetamine) or IR adderall does nothing for focus problems.
