Does it? The amount of active ingrdient in your normal coca leaf (which is all tea is) is miniscule - you need hundreds of pounds to make a gram of cocaine. You could suck back 100 bags of tea and soak them all you want and not even come close to getting "high" - you'd just be awake - coffee or regular caffeine-containing tea is more dangerous than that stuff.
"you need hundreds of pounds to make a gram of cocaine"
I think it's actually 125 grams of leaf makes one gram of cocaine. And a cup of coca tea is like 8% of a dose of cocaine, though it gets absorbed about twice as slow. So it's actually really not that much different than doing cocaine, in that the difference in dosage is only an order of magnitude, although somehow the difference is enough to make the tea completely safe and harmless as long as it isn't abused.
