pretty sure if something appeared then yes
Diabetes alone will not cause a positive drug screen.
No.
ARF (acute renal failure) can NOT cause a positive for cocaine on a drug test.
No, Vicodin will not test positive for cocaine. Vicoden (containing hydrocodone) will test positive for a narcotic. Hydrocodone and cocaine produce different metabolytes, which is what the drug test actually reacts to. A metabolyte is what the drug turns into after your body uses it. Each drug produces different metabolytes.
No.
I have not done cocaine in over 3 weeks and it still showed up in a drug test
Maybe
Yes
No, there is only one drug with a valid use that can give a false positive for cocaine. Cocaine-hydrochloride topical solution. It is used by eye and throat surgeons as an anesthetic.
No, endocet will show positive for opiates.
As long as you didn't use any cocaine it will not show up on your drug test.
cocaine is an opiate... sudaphed can produce positive results for amphetamines(cocaine is NOT an opiate (it is derived from the coca plant not opium), but I do believe sudafed would only produce a false positive for amphetamines)
