Window of detection of cocaine-related alkaloids in oral fluid collected with the FloqSwab™ after coca tea consumption.

Coca tea is a popular drink in some countries of South America, where it is presented as a safe energy preparation, based on a limited total content of cocaine of ∼3-5 mg. Tea bags can be bought with no legal considerations in these countries both by locals and tourists, but its consumption can have consequences when consumed overseas. Driving under the influence of cocaine is banned in most of the places in the world and can be documented by oral fluid testing.
