Squirrel on 'Shrooms- Double Vision

I do not know what is going on with the squirrel population at my house. I saw a squirrel with a monster mushroom yesterday afternoon and Molly and I walked right up on him before he ever ran off. He made sure he took the mushroom with him and scampered up and tree with the mushroom in his mouth. The mushroom is either very tasty or the squirrel is addicted to the hallucinogenic already. I know that they have done studies where various animals have become addicted to alcohol and nicotine and other drugs but I have never heard of a squirrel on mushrooms.
