At age 82my husband was diagnosed with a form of dementia, and was given permission to smoke 1-2 cigarettes a day. He rarely adheres to this and accuses son and I of stealing them. Though he only smokes outside or in the garage, I am finding burn holes from falling ashes on patio furniture and now one inside on the sofa cover. This really scares me, as I occasionally lie down to rest and doze off. I have been startled by the smell of smoke coming from the living room. He insists he only lights up inside and then walks outside. Everything has been such a struggle as he descends into this new world of confusion. Should I mention this to his doctor?
