No absolutely not they are not even in the same class of drugs.
sudafed can give u a false positive for meth be careful
No; Vyvanse is the prodrug of dextroamphetamine. Methamphetamine is considered more neurotoxic than dextroamphetamine.
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.
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.
dosoxyn and yvanse will both show positive in the drug test for methamphetamine
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,it give positive test
No. Their metabolites look nothing like methamphetamine.
No, Benadryl (diphenhydramine) will not give a false positive for methamphetamine. However, Benadryl may cause a false positive for methadone in simple immunoassay tests, though more advanced tests can resolve a disputed result.
