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

Answer 1

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.

Answer 2

No, both will show up as positive for "d" (Dextro) Amphetamine.

Methamphetamine is available in two forms: "d" and "l." These compounds are stereoisomers (chemical mirror images). They have the same chemical formula and similar chemical properties. The "d" form is a prescription stimulant and appetite suppressant. The "l" form is available over-the-counter as the active ingredient of the Vick's inhaler and is a metabolite of certain prescription medications. Both "d" and "l" test positive by both immunoassay and most GC/MS assays. In order to help determine whether a methamphetamine positive may be due to an illicit source, it is helpful to determine the percentage of "d" isomer. For example, following an individual's use of Vick's Vapor Inhaler, the expected result would be 100% "l" methamphetamine. However, there is a possibility that trace amounts of "d" isomer may be present in the quantitative analysis. Laboratory guidelines have been established to allow for trace presence of the "d" isomer. If the laboratory report indicates more than 80% "l" methamphetamine, the results are consistent with Vick's Vapor Inhaler use. If the laboratory reports more than 20% "d" methamphetamine present, the result indicates the use of "d" methamphetamine other than the inhaler. Illegally produced methamphetamine and amphetamine may contain mixtures of "d" and "l" isomers. LabCorp recommends use of a medical review officer (MRO) to review all non-negative test results.

Answer 3

No. Both will show up as amphetamines in drug screens.

Answer 4

There is really no difference between the two on a drug screen; both will show up as an amphetamine.

Answer 5

Yes; Vyvanse is a prodrug for dextroamphetamine. In a drug test, you will test positive for amphetamine use.
