People try to defend positive cocaine test results by claiming they drink herbal tea or visit a dentist who uses procaine as an anesthetic. Although a positive cocaine test result as confirmed urinary benzoylecgonine may result from drinking coca tea, the import of such tea in the United States is illegal. Nevertheless, there are few reports in the literature describing the presence of cocaine in certain herbal teas. Procaine does not contain cocaine and use of procaine cannot result in positive test results. Although some reports describe the presence of cocaine and other drugs of abuse in paper currencies of the United States and other countries, handling such paper money cannot produce a positive drug test in the urine.
