OCC meaning in Airport Code ?

Coca is any of the four cultivated plants in the family Erythroxylaceae, native to western South America. Coca is known worldwide for its psychoactive alkaloid, cocaine.

The plant is grown as a cash crop in Argentine Northwest, Bolivia, Colombia, Ecuador, and Peru, even in areas where its cultivation is unlawful. There are some reports that the plant is being cultivated in the south of Mexico as an alternative to smuggling its recreational product cocaine.It also plays a role in many traditional Andean cultures as well as the Sierra Nevada de Santa Marta (see Traditional uses).

The cocaine alkaloid content of dry Erythroxylum coca var. coca leaves was measured ranging from 0.23 % to 0.96 %. The Coca tribe of Jalisco and Nayarit, Mexico, use it as a stimulant. Coca-Cola used coca leaf extract in its products from 1885 until about 1903, and started using decocainized leaf extract ever since. Extraction of cocaine from coca requires several solvents and a chemical process known as an acid-base extraction, which can fairly easily extract the alkaloids from the plant.
