Yes, there are substances that can cause a false positive on a field drug test. Some common substances include over-the-counter medications, certain foods, and other legal substances. These false positives occur because the field tests are not always specific for identifying particular drugs and may react to similar compounds. A confirmatory test in a lab is usually needed to accurately determine the presence of drugs.

Will allegra-D make a urine test positive for opiates?
It is very unlikely for one drug to cause a false positive on a drug screen for any other substance. Drug screens test for metabolites of specific drugs. All drug tests have a rating based on specificity and sensitivity. The higher the sensitivity, the lower the specificity. Basically it is only possible to have a false positive by using another drug that is very chemically similar to the positive test. It is more likely for Allegra-D to cause a positive result for methamphetamine than any other commonly screened drugs of abuse.
Can a police officer charge some one for the smell of drugs but have not done a search of drugs on the premises?
No I don't think soAdded: They may not make any criminal charge based solely on a smell.HOWEVER, the distinctive odor of many drugs DOES give the officer reasonable suspicion, and even probable cause, to believe that an illegal substance may be present and he may then legally conduct a search without a warrant for the drugs or contraband.
