All I did was use some dried leaf and mixed it with coffee then pour the water in like regular coffee. I poured it through several times till it was like a strong expresso. Make sure you use and old coffee maker you will use just for this, because the regular coffee made in it after did not taste as good. You could also use a pot and a fine filter to do the same thing. The oils in the coffee take in the THC. It is a mellow buzz from what I remember.
