Drinking coca tea could lead to a false-positive result for cocaine. The tea is popular in South America and is made from the leaves of the coca plant, the same source from which cocaine is derived. In a 2006 study, five people drank coca tea before undergoing a drug test.

The researchers concluded that "healthcare professionals should consider a history of coca tea ingestion when interpreting urine toxicology results."
