I am in my 50's & am a retired law enforcement officer (policeman, correction officer and probation officer). I first smoked cannabis in high school but stopped when I got into law enforcement. Both my wife and I use cannabis for medicinal treatment of arthritis, type II diabetes, fibromyalgia, and lupus. I just purchased (probably too soon) a Coldfinger apparatus for extracting the TCH/CBD. I just received it today so I am studying real hard as to properly operate the device which I purchased from Eden Labs. My hoped are to make my own cannabis oil rub on joints and to cook with. I have already learned how to make cannabis butter. And I was curious if anyone could tell me what to do with the water that is left over after the butter making process? It is useful for anything? Any THC in the water vs. the butter? Any info would be appreciated. Thanks.
