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.

Currently taking Vyvanse (lisdexamfetamine) and since it has amphetamines in it, I am concerned I would come out as positive for meth in a drug test. Is this possible?
