Question 1

can didrex show up in amphetamine drug screen?

Accepted Answer

Yes: Benzphetamine is a "precursor" to both methamphetamine and amphetamine, i.e. As the body breaks it down, it becomes amphetamine and methamphetamine before being eliminated.  One study* showed that administration of Benzphetamine resulted in measurable amounts of amphetamine and methamphetamine in the urine.

Question 2

will ritalin (methylphenidate) show up as an amphetamine on a drug screen?

Accepted Answer

No: Drug screens seek drugs of abuse, and false positives are rare because the law requires a positive to be confirmed by another test with a difficult chemical principle. And if the drug is prescribed, i would hope there would be no problem.

Question 3

why do ppl keep telling me that trazodone will show up in my 10 panel drug screen as a false positive? is there any facts to this ? i have a pre-employment 10 panel drug sreen today why is everyone saying i will test false positives for amphetamines?

Accepted Answer

: According to an article (J Anal Toxicol. 2011 Jul;35(6):364-8) The trazodone metabolite meta-chlorophenylpiperazine can cause false-positive urine amphetamine immunoassay result.

Question 4

if i took a vyvanse (lisdexamfetamine) at 7:30 a.m. and submitted a urine drug  screen at 8:45 a.m. the same day, what are the chances it will show up as an amphetamine?

Accepted Answer

Very High: however, if you have a prescription in your name and you are not precluded by court order from taking it there should not be a problem if you showed them your prescription.

Question 5

does celexa and adderall (dextroamphetamine and racemic amphetamine) show up in hair follicle drug screen?

Accepted Answer

Yes.: Detailed testing of hair (not hair follicle) should disclose exposure to these pharmaceuticals. There is however not much clinical value to such testing.

Question 6

is there a med. that has same molicule as meth that shows up on drug screen drug screen pos.?

Accepted Answer

There Are Many: There are many substances that can give a false positive result on routine a routine drug screen for methamphetamine.  Here are some: bupropion, desipramine, any cold remedy obtaining Ephedrine (ephedrine sulfate) or pseudephedrine, and adderall. If one suspects a false positive ask for a true drug test and not just a screen.

Question 7

does pseudoephedrine show on drug screen as meth?

Accepted Answer

No: Pseudoephedrine is used in the making of methamphetamine, but will not show up in any illicit drug screen.

Question 8

how long will literally one hit of meth show up in a lab urine drug screen ?

Accepted Answer

Wrong question.: It is illegal to use methamphetamine, and it is unethical for doctors to tell patients how to pass drug tests. If you can't afford to fail a drug test you can't afford to use methamphetamine. That notwithstanding there isn't a dirtier drug you could choose with greater risks associated with use. Just don't. And don't expect a any ethical doctor to help you do anything but quit. Please get help.

Question 9

what is the probability of a skin patch drug screen returning with a positive result for amphetamines. if the female wearing it is clean completely & has intercourse with a male user. will enough metabolite be absorbed to register & reach the cutoff?

Accepted Answer

: Just having sex with a user should not result in a positive drug test for the female. However, I question the wisdom of the female in being involved with a drug user.

Question 10

doctors, can my drug screen analyzer tell the difference between adderall (dextroamphetamine and racemic amphetamine) and meth or street amphetamines?

Accepted Answer

Yes: a good Drug testing protocol and an experienced Medical Review Officer should determine whether your drug test is truly POSITIVE.
