How can methamphetamine show up in your system if i don't smoke meth?

Answer 1

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.
