Found this post after having the same question. Would fat in the water give the thc something to bond to? Or could one use a cheap vodka that is at least 50% water to steam the herb in?. I know that the alcohol would probably burn off first but what would become of the weed/water? Could it be brewed with coffee and have an effect. There is "oil" in coffee. Would that be enough fat/lipid material for the thc to bond to? Just trying to expand my knowledge of science. Any help or educated guesses on the topic would be appreciated.
