Generate text that refutes this claim: Coca chewing is not equivalent to the consumption of hard drugs. It is no more harmful than drinking coffee.  The coca leaf, in its natural state, is not even a narcotic, even though the 1961 Single Convention on Narcotic Drugs considers the natural leaf to be so. However it only truly becomes a narcotic when the paste or the concentrate is extracted from the leaf to form cocaine. [1] The simple coca leaf, by contrast, only has very mild effects when chewed and is different from cocaine. In 1995 the World Health Organisation found that the “use of coca leaves appears to have no negative health effects and has positive therapeutic, sacred and social functions for indigenous Andean populations.” [2] It may even be useful in combating obesity, and there is no evidence that coca use is addictive. At worst, it is comparable to caffeine in terms of its effect on its consumer. [3] Therefore there are no significant health reasons behind this ban on the cultivation of coca leaves for their chewed consumption in its traditional form.

Compulsive Coca chewing may compromise oral health. The wider cultivation of coca plants may make cocaine itself more readily available, and cocaine has clear health risks to its consumption. This debate must be seen in terms of the wider health risks and problems that actually occur if cultivation is legalized, not just a narrow understanding of the health risks in a theoretical vacuum.
