Lottery I definately know what you mean. I was at one time a scrub tech at Barnes and Jewish Hospital in St. Louis. Guess what I was doing there?
I worked in the ENT Operating Room assisting in the surgeries to remove those cancers. The one like ODT had done, did a bunch of those procedures. Big incision side of face and neck, remove tongue, larynx, lymph nodes, jaw, teeth, yup all gone, big hole in the throat so they could breath, having food pumped into their stomachs by a tube, because you can't eat or chew by mouth. Forgot to mention the skin grafts and the flaps of tissue from your forearm or calf so they can close the hole in your face.
I would leave the hospital get in the car and throw a fatty in. Not once did I ever think that I would be one of those people. Shit, they were scumbags, alcoholics, homeless. I never told myself they chewed tobacco.
I have worked with a few Dr's who dip, chew, or smoke tobacco. After all they are human too.
