Caffinated Green Dragon?

Has anyone tried adding caffeine to Green Dragon? What where your results?

Id imagine one approach could be simply running some of the alcohol through a coffee filter with ground coffee beans in it, then drop in the bud and shake/wait. Basically make something like coffee vodka and infuse some THC.

I wonder if absorbing too much of the coffee may interfere with the alcohol's ability to absorb the THC. I wonder if the caffeine could allow the body to uptake more THC when consumed.

Might taste like hell

Well, since coffee seems to be extracted into water, which is polar, and THC is extracted into butter/oil/alcohol, which is non-polar, I would imagine the coffee would be extracted into the water portion of the vodka and the THC into the alcohol portion. So it shouldn't affect the potency.
dunno bout the taste though, but then again i've never made any kind of coffee vodka, THC or not

i would try with guarana if i knew where to get it. not sure i would enjoy the flavor of the coffeepot (TM), but then again i enjoy the flavor of anything made with herb. especially the inside-out weed-cheeseburger
