There are many OTC medications that can give a false positive on the more common urine tests for drugs.

Yes most def. there are tons of things that can cause a false positive
or a negative if you use a drug test.

Look up Detection of Cocaine in Urine / Toxicology Lab Reports.

Impurrfect

I've been told, by someone who performed lab tests, that sudafed and several other OTC meds can cause false positives for METH, particularly if it contains pseudophedrine.

I've not heard of anything that causes a positive for cocaine, other than what cynical mentioned.

Hugs and prayers!
