Thanks for the reply Stinkyattic, but I am not interested in an espresso machine for making cannabis coffee.(for that I add green dragon made w/Amareto to my coffee) I was wondering if there isn't a way to utilize the power of the steam to extract concentrates from the herb. That was why I inquired about using weaker vodka (more water) to steam the cannabis. I am chemistry ignorant, but considering the results of water/steam shot though coffee beans just thought there might be some potential here and wondered if anyone else had tried any experiments along this line. Just trying to expand my knowledge of science.
