Had a buddy that had a mice problem in his cabin in the woods. He made some real potent canna coconut oil after a good harvest. He left the random leftovers from the process in a metal bowl on the floor overnight to see if anything would happen to the mice. In the morning there were two dead mice floating in the weed water / coconut residue. Clearly overdosed. He tried a ton of things to get rid of the mice and weed worked in eight hours.
