Coca tea is really nice, like green tea, but a milder stimulant effect & nicer taste. Can start to catch a bit of a buzz after about 10 cups, with no jitteryness like I'd get from caffeine. It seems expensive for what it is online & I wouldn't want customs to seize it, I just got a box of Zurit tea bags when a friend brought some back from Peru years ago. I'd drink it all the time if it was cheap & legal here.
I'm not a fan of cocaine, but coca tea is different, it's very mild & has a little relaxing effect too.
