Response: Re: Myocardial Infarction Associated with Adderall XR and Alcohol Use in a Young Man

To the Editor: Thank you for the comment. The drug screening test cited in the article is the standard 9-panel urine screening test. It doesn’t distinguish between amphetamine and methamphetamine and reports as methamphetamine. There is, however, a more specialized test that can detect only methamphetamine. To my knowledge, methamphetamine is not one of intermediate metabolites of either amphetamine or dextroamphetamine.
