base. The amount of coca alkaloid in the raw leaves is small, however. A cup of coca tea prepared from one gram of coca leaves (the typical contents of a tea bag) contains approximately 4.2 mg of organic coca alkaloid. (In comparison, a typical dose (a "line") of cocaine contains between 20 and 30 milligrams.) Owing to the presence of these alkaloids, coca tea is a mild stimulant; its consumption may be compared to consumption of a moderately strong cup of coffee or tea. The coca alkaloid content of coca tea is such that the consumption of one cup of coca tea can cause a positive result on a drug test for cocaine, however. Similar to

in coffee, coca tea can be decocainized. Just as decaffeinated coffee retains a small quantity of caffeine, decocainized coca tea will still contain a small quantity of organic coca alkaloids.
