Will meth show up as adderall in drug test?
YES, Adderall and other stimulants based on amphetamine will
cause a UA or a swab to show up as "hot" for amphetamines.
Remember, standard drug tests do not test for the drug itself,
they test for the metabolites of the drug, i.e. what your body
turns the drug into. Since Adderall is a mixture of four different
salts of amphetamine, your liver metabolizes these salts into the
exact same chemicals that meth metabolizes to.
Hope this help you out.
