You can use full fat milk. Boil it up in a pot, add your weed, the fat content in the milk will allow the thc to bond with it. Granted the milk does go a light green color. Once you add the coffee it will go a normal coffee color. I've canna milk lots of times, I do it the way I've stated, let it cool then stick it in the fridge. I add nesquik to it and drink it as milk shake or put it on my corn flakes. Once I read this post I tried it with coffee, obviously just using milk instead of water added the instant coffee abduction sugar (we call it a milky coffee in Scotland) can't say I was really high. Just had a i don't give a shit I'm to relaxed attitude all day! Lol
