No it doesn't.
No. And thats even when we know that it can seriously harm some people, because of a chemical it creates as it is digested that a few people cannot process. It doesn't, however, cause cancer.
Me neither... squash FTW.
And yes.. they did, its where the "Coca" bit in the name comes from.
Not quite. The 'Coca' part of the name comes from one of the ingredients, coca leaf, which is indeed also what cocaine is derived from. However to produce cocaine you have to process it. Coca Cola used to have what amounted to 'trace' elements of cocaine in it - they used the same leaves that cocaine was made from, but they didn't intentionally add cocaine to it. They later used the leaves that had already been used, leaving trace elements of cocaine in it again. Now they use extract.
It was originally sold as a medicine, funnily enough, since to this day people still claim it cures headaches.
