I wonder if there's cola that is still made with active coca ingredients somewhere in the world. I believe chewing on coca leaves is legal in some parts of South America and cocaine is legal in some european countries... with the recent "boutique soda" craze, it must exist.
It is decriminalized in Portugal but that is not the same as being legal. I'm fairly certain that it is not legal in any European country and I know for a fact that it is in the EU controlled substances list and is not legal in the EU except for a very few and very narrow uses in medicine and pharmacology.
In Peru and Bolivia, coca leaves are sold just about everywhere. A good tasting tea is made from them, and people chew them while hiking on the mountains and so on. The effects are similar to caffeine. I didn't see any coca soft drinks there, though.
Also, according to Wikipedia[1] Coca Sek, a coca leaves based soda is still sold in Colombia, even though is was removed from super markets shelves.
I was living in Colombia when it was launched. It had a big media coverage, so I tried it once just out of curiosity. It tasted really really bad and I didn't notice any side effects after managing to drink just half bottle.
