Don't Get Stoned

I sketched out what appear to be some random stones/rocks. I got the image in my head earlier today while I was pondering the many reasons behind a person's substance abuse and all of the slang/vernacular that goes along with it. I wasn't thinking about anyone in particular. One of the phrases people like to throw around is "Are you stoned or something?" The first time I heard that phrase was in some movie and then later all throughout high school. I've always wondered why people associate an inanimate stone with an altered state of consciousness. Hmmm.
