No. A drug test is a colored strip dipped in the urine. The person administrating the test has to let the strip sit in the cup or urine for about 15-30 seconds to ensure an accurate result. If the strip had a certain code, or color on it, then it will show either positive or negative. Either way it takes relatively the same length of time.

You must have taken something similar - here's a good link showing some substances that can cause false positive drug test results.


You are on methadone and your drug test said you were positive for codeine you don't take codeine just vicodin I'm having trouble making them believe you what can you do?

The results show positive for codeine because methadone is in the same family. Show them your prescription for the methadone and tell them that this drug is in the same family and will show positive.


Can Celexa show a false positive for cocaine in urine testing?

No. Not even in an alternate universe where citalopram IS cocaine. It just won't happen. People who take (or "used to" take) drugs and are faced with a drug test that shows positive results are almost certainly lying if they say "No, I did not take X drug" when X drug shows positive on the test. False positives on urine tests RARELY happen. We're talking about science here, people.

Time it takes to get results of drug test?

Some drug tests are almost instant. Tests for residue on skin for marijuana, cocaine, meth, and several other drugs can be done in real time. Results for drug tests that employers specify can usually be completed in a day. Results for criminal drug tests can take much longer. Toxicology done by the coroner, where so many drug abusers wind up, usually takes 2 or 3 weeks.

Does risperidone produce false positive in drug tests?

Risperidone itself is not known to produce false positives in drug tests. However, certain types of drug tests may not differentiate between risperidone and other substances, potentially leading to a false positive result. It is important to inform the testing facility of any medications you are taking to avoid such confusion.


Can Aderal drug cause a positive reading for cocaine on a drug test?

No, Adderal shows as Amphetamene & Cocaine shows as Cocaine. A specific drug test done for Cocaine only reacts to the specific drug Cocaine. If you are being tested for ALL drugs, then whichever drug consumed, or both, will show in the test results.
