In Peru, the National Coca Company, a state-run corporation, sells cocaine-infused teas and other medicinal products and also exports leaves to the U.S. for medicinal use.Visitors to the city of Cuzco in Peru, and La Paz in Bolivia are greeted with the offering of coca leaf infusions (prepared in teapots with whole coca leaves) purportedly to help the newly arrived traveler overcome the malaise of high altitude sickness. The effects of drinking coca tea are mild stimulation and mood lift. It has also been promoted as an adjuvant for the treatment of cocaine dependence. One study on coca leaf infusion used with counseling in the treatment of 23 addicted coca-paste smokers in Lima, Peru found that the relapses rate fell from 4.35 times per month on average before coca tea treatment to one during treatment. The duration of abstinence increased from an average of 32 days before treatment to 217.2 days during treatment. This suggests that coca leaf infusion plus counseling may be effective at preventing relapse during cocaine addiction treatment.There is little information on the pharmacological and toxicological effects of consuming coca tea. A chemical analysis by solid-phase extraction and gas chromatography–mass spectrometry (SPE-GC/MS) of Peruvian and Bolivian tea bags indicated the presence of significant amounts of cocaine, the metabolite benzoylecgonine, ecgonine methyl ester and trans-cinnamoylcocaine in coca tea bags and coca tea.
These strains have also shown to be more potent than those previously grown, increasing profits for the drug cartels responsible for the exporting of cocaine. Although production fell temporarily, coca crops rebounded in numerous smaller fields in Colombia, rather than the larger plantations.The cultivation of coca has become an attractive economic decision for many growers due to the combination of several factors, including the lack of other employment alternatives, the lower profitability of alternative crops in official crop substitution programs, the eradication-related damages to non-drug farms, the spread of new strains of the coca plant due to persistent worldwide demand. The latest estimate provided by the U.S. authorities on the annual production of cocaine in Colombia refers to 290 metric tons. As of the end of 2011, the seizure operations of Colombian cocaine carried out in different countries have totaled 351.8 metric tons of cocaine, i.e. 121.3% of Colombias annual production according to the U.S. Department of States estimates. Synthesis
Synthesizing cocaine could eliminate the high visibility and low reliability of offshore sources and international smuggling, replacing them with clandestine domestic laboratories, as are common for illicit methamphetamine, but is rarely done. Natural cocaine remains the lowest cost and highest quality supply of cocaine. Formation of inactive stereoisomers (cocaine has four chiral centres – 1R 2R, 3S, and 5S, two of them dependent, hence eight possible stereoisomers) plus synthetic by-products limits the yield and purity. Trafficking and distribution
Organized criminal gangs operating on a large scale dominate the cocaine trade.
