Uh, having methamphetamine in your system! But other sources say the following can also cause false positive results: Desoxyephedrine, Desoxyn, Methedrine, Vicks Inhaler (non-prescription drug), Selegiline, Benzphetamine and Famprofazon, Dexedrine, Benzedrine, Adderal.
I'm guessing no
About the same as anyone else, but at 350 lbs you should just get a prescription for desoxyn and it won't matter if you test dirty.
no
methamphetamine is sold as a prescription drug under the name Desoxyn, so needless to say prescription meth would test the same as street meth
She would most likely test positive for methamphetamine and amphetamine. One of the breakdown products of methamphetamine is regular amphetamine, so a positive result for methamphetamine is basically needed to discriminate a positive amphetamine as due to ingestion of meth vs ingestion of amphetamine. So basically, your sister's test should be positive for methamphetamine also if she did crystal meth.
Methamphetamine can be detected in a drug test even if one does not smoke/abuse meth. One way this is possible is that methamphetamine was ingested in another way, such as orally in the form of prescription pills (Desoxyn is a prescription form of methamphetamine hydrochloride). Certain decongestant inhalers also contain an isomer of methamphetamine. Though this compound lacks the abuse potential of its enantiomer (non-superimposable mirror-image molecule), it may still show up as 'meth' on a drug test. Finally, other medications can also cause false positives for methamphetamine on certain tests. If one test gives a positive result, more advanced tests can be used to distinguish between positive results and false positives. If one has used the aforementioned products which contain methamphetamine, this should be brought to the attention of the test administrator.
Yes! Since Meth is made from it, if you take enough of it, you can eventually test positive for methampethamines. You can also test positive for meth if you take a lot of Sudafed and other cold medicines.
No, Allegra allergy medication should not cause a positive result for methamphetamine in a drug test. Allegra contains fexofenadine, which is an antihistamine and does not typically cross-react with drug tests for methamphetamine.
dosoxyn and yvanse will both show positive in the drug test for methamphetamine
No, it is a glucocorticoid steroidal antiinflammatory medication that should not test positive for methamphetamine, nor should it metabolize to any substances that yield a false positive for methamphetamine.
Desoxyn and adderall, maybe Vyvanse, and other ADHD medications
