My client is a 48 year old man with dementia & schizophrenia. Test showed his lungs are scared from tuberculosis. He sneaks around and smokes cigarette butts he finds on the ground. He normally does not smoke, but about once or twice a month I catch him smoking butts. I'm not sure how to handle this. His doctors have told him he is not to smoke, but he does it anyway. Any advise would be greatly appreciated.
