Help can codeine sulfate and hydrocodone show up as the same in a simple drug test?

Help can codeine sulfate and hydrocodone show up as the same in a simple drug test?

Yes: Drugs tests look for 2 essential chemicals when they look for opiates - Codeine and morphine, which are similar compounds and they are both converted into each other. Hydrocodone is metabolized into Codeine which is then transformed by acetylation to morphine. These are the final common pathway products for most, but not all, opiates. Oxycodone produces relatively little, is has separate test. ...Read more

Can tylenol with codeine show as coke in a drug test my sister in law to a drug test, she was taking tylenol with codeine, the test came out positive for cocaine, can this happen?

Can tylenol with codeine show as coke in a drug test my sister in law to a drug test, she was taking tylenol with codeine, the test came out positive for cocaine, can this happen?

Cocaine is cocaine: If Cocaine is positive on a confirmatory urine drug screen (e.g.Lc/ms), 99.99% it is cocaine. Specificity for both screening & confirmatory urine tests for Cocaine is very high, thanks to its unique molecular structure. Even similar substances in the -caine class such as lidocaie, marcaine, etc. Do not cause a false positive Cocaine on a urine drug screen. ...Read more

What are some medicine that might come out positive as meth on a drug test medicine i take prometh/codeine, prednisone, advair, hydroxzine. False positive for meth

What are some medicine that might come out positive as meth on a drug test medicine i take prometh/codeine, prednisone, advair, hydroxzine. False positive for meth

None of the above: There are many false positives for all amphetamines, but not specifically methamphetamine. Proper drug testing goes beyond the screening test - if that is positive definitive testing should be done, which will eliminate essentially all false positives. Every cold medication around can give a positive amphetamine, but not a positive for methamphetamine. You need to demand the definitive test. ...Read more

Fioricet with codeine on drug test, will I pass?

No: it contains, obviously, codeine which will show up as an opiate (and is also metabolized into morphine). It also contains a barbiturate, bultalbital, which will also show up as positive. I would worry more about using drugs when you are subject to drug testing, and the level of severity of your drug problem, as you do about getting caught. ...Read more
