Coca plant tea boiled down to a syrup from the coca leaf, the same leaf cocain is made from, is one of the two flavorings in Coca Cola the other being African kola root. At one time far back Coca Cola was something of a spike with a very small amount of processed cocain from the coca leaf added. Today Coca Cola  for a flavoring uses only the common South America tea called mate or mata which is simply coca leaves put in a pan of boiling water and boiled into a pleasant tea. Contrary to what you get on the web mate tea in coca cola for a flavoring is not decocainized it is simply a mild tea sold in restaurants all over South America. Agriculturally coca plant grows prolifically down in the Cochabamba area of Bolivia. Occasional excerpts from Bolivia newspapers commercial sections while in Bolivia give the number of coca leaf bales shipped to Coca Cola here and there for its flavoring. It is an agricultural product in Bolivia for Coca Cola, medicine. And it is a crop like alfafa (can you imagine regulating alfafa) with no way to stop its sale to illegal Cocain producers for advanced processing into Cocain for drug use to get high. Cocain can be a very dangerous drug. The drug test whether someone has been on cocain does not differentiate between mate tea, coca cola or cocain. Absolutely you will test positive for all three for cocain. Actually the test is for coca leaf as common as alfafa agriculturally in some parts of South America. There is no way not to get a positive cocain reading and never will be from drinking a bottle of coca cola. Thus coca leaf is very much the popular coca cola, a much needed medicine, and not needed Cocain. Cochabamba Bolivia is the capitol of coca leaf. I have been at the mercado there with its numerous huge bins of coca leaf, as many types as there are corn. A seventh heaven for connoisseurs of coca leaf for the finest restaurants. I like to buy a package and chew it. Most like to boil it to a tea for meals or socialization. I do not know how to differentiate as to what should be favorite as the type of coca leaf for sale in the bins in the Cochabamba mercado. I have thought what would happen if I mixed them and brought them for chewing and tea in a duffle bag through Miami customs reporting coca as an agricultural product. That would raise eyebrows. I think it is legal. That would seem a lot of coca but you would still need a lot more coca leaf to make significant quantities of cocain in a processed formula. Cocain is expensive. I have no idea what that processed to Cocain formula is. Everyone is better staying ignorant.  The GLOBAL COMMISSION ON DRUG POLICY says world control of drugs has failed and broaches the issue of legalization of drugs to get high on (see Al Jazeera June 2, 2011). I have no opinion one way or the other on marajuana which probably approximates alcohol in its dangers (do we want two of them). On Cocain the answer is unequivocally no to legalization of Cocain. When the Mexico ferrocarril train sometimes called the Burro ran through the back area of Chiapas down to Tapachula on the Guatemala border I used it to get to Guatemala. They grow no better marajuana there than here in the Mohawk Valley near my home which God almost seems to have made for growing marajuana. But the New York State Thruway runs all the way through the center of the Mohawk Valley. Visitors exit and look over the countryside. "Isn't that a pot plot over there. I believe it is". Whereas back land Chiapas is not exposed to these visitors. Thus marajuana commerce goes on as an ordinary hum drum agricultural business. The Government of Mexico could offer rewards for the turning in of pot plots. However the Zetas are very active down in that area and always looking for new profit businesses. Just a few weeks ago in Guatemala they beheaded a group of 32 men women children and babies. Thus this leaves this out. Thus Mexico is doing what it can do and at the same time not spending too much money on what it can not really do anything about. The best idea was with the Mexico president, De La Madrid and Ronald Regan, going to education as the best preventative on both alchohol and marajuana those two curses. Much government money of U.S. and Mexico spent on seisure of marajuana is a basic waste. Education is highly profitable and a great cost saving. Both are equally dangerous. As to cocain it must be seized by law enforcement. It can not be allowed to get through.
