I had a few bottles of agwa sent to my house. Too sweet for me (since I'm a whisky guy) and didn't really give me a stimulant type buzz. I doubt there is any cocaine in it.. they most likely use decocainized leaves.
I have ordered leaves many times however, and chewing the quid with baking soda is not disgusting and quite enjoyable. Your mouth goes numb and you get a nice coffee like buzz without jitters and shitty comedown. Highly recommended. Making it into tea is a waste, you need a lot.
I did make a very powerful extract tea once though. It took a whole day, i used about 300 grams of leaves, added some baking soda and like a liter or more of water.. let it slow simmer all day.. then filtered, reduced the liquid to a more manageable volume.. and drank.
It was disgusting but HOLY SHIT did it get me high. Literally like i just blew a phat line.. no joke. It was kind of crazy. I was FUCKED UP!
